IBM PS/55 Z – ATX Motherboard

So, this ended up being a bigger hack than expected... but I'm happy with the result! I picked up this unit from eBay and hoped to use it as-is, but the motherboard wasn't healthy and Microchannel anything is impossible to find. I therefore replaced the guts with a DX2/66 motherboard! It all worked perfectly and I was happily playing games... but then I found a P166 at the markets and felt it was time for an upgrade.

Power Supplies

I picked up a Pico-ATX adapter on eBay rated at '120w' and had very little success with it. I could get it to boot without any cards... but as soon as I added anything on the ISA bus, let alone actual drives, I had zero action. Seems that it's just not up for the current required. I was also feeding it power from the internal 12v on the IBM's motherboard and this may have been overloading a single 12v rail.

It also needed a floppy connector... seems that these are for mini-atx boards where floppies are a distant memory...

Thinking that it just needed more amperes... I mounted a new 12v supply inside the monitor housing...

I grafted this onto the power rail to the front switch of the machine... it was rated at 110-240v, so there were no issues with step-downs...

This then meant the front power led was no longer lighting up, as the internal power supply had no current draw... I had to then use a resistor and put it on the 5v output of the new supply.

But... it still just didn't work... the actual Pico-ATX unit just wasn't up to the challenge of the old P166 motherboard! I then purchased the '160w' version off eBay, but it was EXACTLY THE SAME unit?

Slightly-larger ATX supply

I happened to be near an old PC shop in the city where I'd previously sourced a 'smaller' ATX power supply. Turns out they still had stock! I wasn't overly sure if it'd fit, but I was happy to have a spare in stock regardless. To my happiness, it fit perfectly!

I mounted it under the lid, as per the previous power supply, and ran the 110v in (flicking the voltage selector switch!) from the main power supply. The ATX cable was then fed straight down the back into the motherboard 'compartment'. It booted and the machine was back to normal... this time with W98SE and more horses!

B&O BeoVision MX 7000 RGB SCART

It all started by finding this beast on the footpath. I saw that it had two scart inputs and had to have it. I built an RGB cable for my MSX a long time back but have always been disappointed by its performance via a scart-to-HDMI converter. So, I set about testing and hooking it all up. Of course, it didn't have a remote, so I had to use an Arduino to translate another remote into the appropriate codes.

With access to all the menus, I started toying with values, but the picture from the MSX was still broken!

What can be configured?

Via the front main menu? Nothing. Via the service menu? A lot more. With my model, I had to pull off the back case and short the service pin header (I'd actually really like to just install a pushbutton switch onto that!)

Once off, and with the TV on TV mode, use something metal to short those two pins in the middle that say Service Mode. You'll then get the following message on the TV...

Last error was a pf? Sure was... I just pulled the plug... total power failure! Here's the other error descriptions...

Code	Description
No	no error registered
PF	Power Fail
00 till FF	Error address on the I2C bus
DF	Data failure (maybe EEPROM 6IC6 on the cpu board defect)
4E	1/38IC6 Tuner & IF port expander
84	1/38IC2 A2 Stereo decoder
40	31IC7 NICAM stereo decoder
42	41IC5 D/A converter for cut-off and drive
22	37IC2 Teletext decoder
8C	13IC2 Deflection controller
82	14IC1 Audio Controller
86	14IC9 Video Controller (14IC9 means Board 14 Chip IC9)

Anyway, using the arrow keys, you'll be able to configure the following settings. There's an awesome thread post here on BeoWorld from Die Bogener explaining all sorts of troubleshooting for the TV!

Code	My Default Value	Description
Rdr	50	Red drive
Gdr	45	Green drive
Rcu	28	Red cut off balance
Gcu	29	Green cut off balance
BRI	03	Brilliance Preset
COL	03	Color Preset
Hfq	37	Horizontal frequency
Hph	35	Horizontal phase
Ham	22	Horizontal amplitude
Vam	29	Vertical amplitude
Vsc	32	Vertical S-correction
Vsh	30	Vertical shift for centering
Vli	18	Vertical linearity
EWc	05	EastWest corner
EWp	1	EW parabola
EWt	41	EW tilt

With all these settings being adjusted (and then reverted) to no avail... I started to wonder if it wasn't a Japan vs. Australia thing... NTSC vs. PAL? Does the RGB signal have a 50hz/60hz rate or other 'remnants' from the units output? Is it Australia's fault for successfully implementing only one standard? (For once!)

Does RGB care about NTSC or PAL?

Wherever you read, you'll find hot debates over RGB and how the signal differs from a PAL or NTSC console. From what I understand, it's a NO. Any TV with SCART that is RGB capable will take an RGB signal from any device. Do correct me on this, thought!

Can My TV Decode NTSC?

Here's the service manual which points out the following difference between the PAL and PAL/SECAM versions...

Yeah, that's not just PAL/SECAM... it's PAL/SECAM/NTSC! But wait... the MSX works over Composite? Which has to be NTSC-J Composite? What gives?

Maybe it's my RGB Cable?

There's a good bit of information at this post regarding RGB cable issues and required voltages. Supposedly the SYNC signal on the SCART plug can just be fed Composite video, but it needs to be within tolerance. This also goes for the switching which declares what video format is expected on the SCART plug. So, after reading more on Sync for SCART , Sync Strippers and types of Sync from random consoles.. I ended up slightly more confused, but decided to rebuild my cable.

Thankfully, my junk box had a beautiful SCART-to-SCART cable... I didn't know these existed, but it makes total sense that they do. It's wired as a 'crossover' as the output from one machine needs to be fed to the input from another. I'll never be outputting via a SCART plug, so I decided this hefty cable would shield me nicely from interference and provide a great base for a proper RGB cable for the MSX.

With the SCART pinout in one hand and the Japanese MSX RGB pinout, I set out to rebuild the cable... I hooked up the minimal wires: R,G,B and Sync + all their required grounds. This got me nowhere. So I then hooked up Ys to the 'output select' and I received a mis-coloured picture!

I quickly slapped spacebar... the fish are the screensaver for multemente on MSX...

Oh right, I've swapped G and B around... wait... it's reading the RGB channels? But wait... if I then switch the TV to DVD... bang... wrong format!? Wait... this has worked all the time? I hadn't noticed the clearer picture... I'd just thought it was pulling composite over SCART... instead it was actually displaying the correct picture. For some reason, the TV is expecting a different format on V.Aux and that's where it's screwing up. RGB WORKS!

It turns out that, if you have your SCART-connected device turned ON, then the TV tries to switch to its input, even if you've selected the wrong input? Seems to be a bug? Or a problem with my TV configuration? The TV was configured as follows...

I set out to test: PS1 in AV1 and MSX in AV2. The PSX worked perfectly when the MSX was off and the TV was set to 'DVD' (which was the setting of AV1)...

But as soon as I turned on both consoles, the MSX would trigger the AV1 channel to distort. Switching to V.AUX (or AV2, where the MSX was plugged in) worked! So, all this time... everything was working, I just didn't understand (still don't!) how the inputs work on the MX 7000. All I know is that you should only have one input powered up at one time! So, here's some RGB goodness...

SCART cable quality!

This has all occurred because I saw the quality of the original SCART cable and thought it was composite! Here is the old cable plugged back in again. Note that it's just 8-core wire, no shielding... so the quality sorta makes sense...

Compared to the shots above, you can see the distortion. But I admit, it's really hard to take a proper photo of a CRT! So.. it was nice to build a real cable.. although, dealing with the gauge of wire was a little tough. It seriously had a mind of its own!

Both units need an overhaul

Whilst doing all this research, I found notes on both items for overhauls! Seems that an urgent capacitor replacement should be carried out on any Japanese MSX with a specific daughterboard. Also, the BeoVision MX Service Guide indicates a whole bunch of capacitors that could be life-expired!

B&O BeoVision MX 7000 Homebrew Remote

After picking this TV up off the footpath, I found it to be a little tedious without a remote. A quick google saw that it needs a specific B&O remote and not just any universal contraption. From here, I managed to use my PC's serial port and WinLIRC to control the TV, albeit rudimentally. The MSX, whilst over SCART, wasn't displaying a proper picture, so I knew I needed a proper remote to flick through the settings quickly.

Arduino as a remote translator

I found a neat little Arduino Remote at Jaycar and decided on the spot that I'd use an Arduino to translate its buttons to those of the TV. This would require an IR Receiver and an IR Transmitter. I know the B&O tranmission needs to be fast, but the receiver can be anything off-the-shelf as long as it works with this remote below!

Thanks to Sparkfun's great IR tutorial, the build of the actual circuit was very simple. Two modules and a resistor! Make sure you point them in different directions so as to prevent one remote from interfering with the other.

Ken Shirrif's IRRemote Library is the only code library needed to get up and running. I then started searching for help on timings... It turns out that someone else has already requested this functionality but there's no confirmed results. Fortunately, there's a few good hints towards the bottom regarding transmission signal timing. Supposedly the library can be tuned to just output the data at the right frequency... so... let's try! We do get another hint here about setting the right timing, but with a warning that the timing might not be 100%. It seems that the unit can deal with a 10khz difference.

Anyway... I was going to go long-winded with a simple chunk of code to just send a power-on, then a chunk to receive the data from the cheap remote, then a bridge to bring it all together... but instead, here's the answer.

You'll note that I have a V.Aux button configured up there. Turns out that I couldn't set both SCART plugs to DVD and cycle through... one would default to V.AUX automatically when trying to set the first to DVD. I therefore had to be able to press the button. The base configuration didn't have this coded! Ah! Found the button here. I have a suspicion there's a host of other buttons to map... Maybe I should go and buy a remote.

Meanwhile, turns out that this thread is the source of the correct configuration. Doesn't seem to have all the buttons though!

With all this done, attempting to get to the service menu with MENU,1,1,GO doesn't work. I do get the software version with MENU,0,0,GO... So I may be locked out. Regardless... I wasn't able to fix the issue I actually wanted to: the MSX still hates RGB. Loves Composite though!

B&O BeoVision MX 7000 TV

So this is nothing short of weird... After having to walk half-way across Melbourne to get home (thanks to the train lines being shut for upgrades), I find this unit sitting out the front of my apartment building. The weird part is this: I swear this is the exact same TV I saw in a 'vintage shop' in Geelong around a year ago. Geelong is a long way away... and for this ridiculously heavy unit to appear in front of my apartment... in dirty-but-OK condition, is totally surprising.

Of course, this is Melbourne and just maybe there's a lot of rich people with expensive+vintage TV sets just sitting around...

Does it work?

I threw caution to the wind and found a protected power board to plug it in to. A quick visual inspection before hitting the switch and click... we have a red stand-by light! A quick search of the front panel found a power button bottom-right and, tapping this, the unit came to life!

No remote control

Not a deal-breaker... or so I first thought. Turns out B&O decided to use a non-standard IR frequency and standard universal remotes just won't work. LIRC was fun back in the day, so I installed WinLIRC and tried to load up the easy-to-find Beo4 Configuration. Before even trying to hack together a transmitter, I was hit with errors trying to load the configuration.

Not very helpful at all! I hacked around with configuration file and found that it didn't seem to like the area between the raw_codes begin and end. Darn... maybe it's an archaic Windows version... so I installed Mint on the old Intellistation Z and tried again...

After booting into Linux Mint, I installed lirc with sudo apt install lirc. No issues here, so I downloaded and copied the Beo4 configuration to /etc/lirc/lircd.conf. A quick sudo service lirc restart and syslog tells me:

steven@intelli ~/Downloads $ sudo cp Beo4 /etc/lirc/lircd.conf

Oh! Right! Here's the actual error! WinLIRC just 'failed', whereas I get proper verbose logging in Linux. Turns out the configuration file is just no good. I ended up browsing back to the lirc page, in a vain attempt to find a forum or mailing list to whinge to... but then... I found the real remote repo! Scrolling down... lo'n'behold is the Beo4 LIRC Configuration File with happy 'compatible' ticks. Opening it, I can see it's a completely different file!

And that's as far as I got on Linux... For the life of me it wasn't worth the effort trying to work out how to use /dev/ttyS0. It seems that the kernel hogs it and you have to setserial and stuff... so I just re-booted back into windows... on a machine closer to the TV...

Just because Windows is easier and I'm lazy, I plugged the file into WinLIRC... It worked! We're set... time for some actual hardware to get the IR transmitting.

Transmitting signals...

I found some IR sensors that I had lying around... they're TCRT5000s and I only need the transmitting half. That's the half with the bevelled side (when you're looking at it) and the anode is up top. A 220ohm resistor was tied in-line to prevent excess serial current draw.

The contraption was pointed at the TV, but no amount of clicking would work to turn the TV on. I was about to give up, but decided that the transmit power could be an issue and held the IR LED 5cm from the receiver. Presto! Power-On worked!

I plugged the MSX into the SCART plug and got the following... more research to be done! I also need a better mechanism for pressing remote buttons if I'm going to go through the menu and adjust settings.

What about Arduino?

Having a whole computer to control a TV isn't optimal... so...Arduino time! Well.. it will be in the future... after I read this, this, this, this and this. The goal will be to build a controller with enough buttons to re-configure the input... hopefully... to get the MSX to display!

UPDATE: Arduino Remote works like a charm!

Sony Playstation

I suddenly realised that I actually did have a device to plug into this monstrosity. The original Sony Playstation gathering dust under my coffee table has Composite out! Of course, the TV does not have Composite in... so I had to improvise with a Composite-to-SCART adapter.

Yey! Abe's Odyssey!

Sony HITBIT HB-F1XD Floppy Drive

Hello again Mr HIT BIT. I bought this unit a while back and never got around to testing the floppy drive...

As you can see from the image below, there was a sticker attached that said the Floppy drive was problematic. (フロッピーディスクは動作しません)

This didn't worry me too much, as I intended to use the cartridge slot more than the floppy drive. Regardless, I wanted to eventually test it out. I actually even bought a random second-hand disk from a second-hand shop in Japan whilst purchasing the main unit.

Based on the sticker... the first goal was to inspect the drive!

Pulling the unit apart

In full Sony-style, there's 6 screws (with arrows pointing to them!) on the underneath of the unit that need to be undone. Once they're out, flip the unit back on its base and remove the cover left-to-right. The floppy disk eject button is seated through a hole in the top half of the case, so be careful when removing!

Once off, there's a shield on top of the floppy drive to remove. This has one screw top-right. Undo the screw and then use a flat-head screwdriver to prize off the clips along the back of the floppy drive. After this, there are then three screws that hold down the bracket that the drive is attached to. With these out, you can then perform a back-flip with the drive and expose the wiring. It turns out it's a 34-pin data cable and standard floppy drive power cable!? But with only the 5v wiring.

The drive itself

Things got interesting from here... after removing the top case (more clips, use a flat-head screwdriver), I noticed that there didn't seem to be a drive-belt at all. All articles online indicated that these drives had belts and are known to perish over time. I started pulling the drive apart further and found out that Sony actually chose to split the drive motor across the base PCB!? Talk about a nice way to save space... and not have to need a belt!

Talk about mesmerising... those copper coils are beautiful! But dang... I'd gone and bought a belt and everything... if this still isn't working, as per the sticker, then I'm really in trouble!

Testing the drive

I put it as-back-together-as-needed to test the drive and turned it all on. I put the disk in, but all was very quiet. My MegaFlashROM loaded into Nextor and I hit the number '2' key to switch to the second drive.

What? It works? MENU.BAS sounds like a good place to start...

Ok, here we go... is this a demo disk? "Tanaka Yatsuu Shin"? I'll need a bit of help translating this... regardless, "CG" sounds like fun!

4 Images? Here they are in order...

I had it all working nicely, but the machine was half apart... so I screwed it all back together.

Floppy Drive Issues

Once back together, the drive refused to read. Taking it apart bit-by-bit, it started reading again once the drive shell was off... but this wasn't reliable either...

Gosh-darn... it's time to dig further into this drive... It seems I can wire in a PC drive.. but first I'll open the whole unit up again and give it a proper clean. It felt like it was having issues understanding that the disk was in the drive... I'll start there and determine what sensors are used and if they're functioning correctly... but that's all in the new year!

Digital 54-22703-01 Motherboard – L2 Cache

After making this motherboard fit into the IBM PS55/z, I realised I hadn't decked it out fully. I'd mentioned cache in the first post, and finally got around to ordering some. The goal was to speed up the poor old 486 as it wasn't running as fast as I would've expected it to. Of course, this was also all very subjected as it'd be pretty impossible to actually remember how fast my first PC actually ran!

Usually, parts like this can be pilfered from other items laying on the shelves in my apartment, but this motherboard needed specific 'TAG' RAM, as well as the standard 32KBx8 static RAM chips. I had to go hunting...

Required components

Back to Pafe 45 of the User Manual for this motherboard and we find that we need eight 32 KB x 8 cache SRAM chips and three 16 KB x 4 cache tag SRAM chips to max it out. Straight to eBay and I found a seller in Israel with the correct parts. I incorrectly ordered two sets of TAG RAM chips and only half the required static RAM chips... whoops... fortunately I could pilfer those off another board!

The TAG RAM chips are labelled MCM6290BP25 RIQAB9131.

As per usual... always be careful when inserting ICs. Make sure their legs are aligned with the sockets and don't press until it's safe... otherwise this happens!

With everything in, we just need to adjust the jumpers...

Set all four jumpers (J3,J4,J6,J7) to 2-3... and then boot!

Yosh!

Test Software

Go here and download anything that starts with Cache. I then tested them all out...

They all showed that any data size under 256kb proved quick response times. The rest started spiking as more operations were required. The CCT386 application had awesome graphs.

Now to work out if the games actually operate faster...

Microchannel Sounds Cards (aka Hen’s Teeth)

I was interested in these when the IBM PS/55z was on its way as I wanted to deck the machine out with sound. Turns out that MCA is a rare breed and actually-interesting cards are impossible to come by.

Imagine my surprise when I saw an MCA ChipChat Sound Card (with wavetable addon!) appear on eBay. It started at AUD$50 and I was interested... just because it had to be an investment to sell later?

Here's the description...

This a ChipChat Sound-32 Card for a IBM PS/2 Microchannel computer.
It comes with original box and contents. Including reference disk and driver disk.
Drivers are for DOS, Win (3.1, 95, NT), OS/2 (2.x, Warp)

And a few pictures:

So yeah, nothing special... not even a mention if it works? Anyway... the 7 days were nearly over and it had gotten up to AUD$141. I was a little disjointed, but yeah... it's a relic! I mean, it's beautiful.. but... I wasn't expecting the outcome:

I'm very happy that someone, who I hope REALLY REALLY wanted it, got a very nice piece of computing history!

Testing EGA/CGA Cards

I'd picked these up a while back but never thought I'd get to test them. I don't have any monitors that support the old standard and haven't actually seen any available on eBay for a long time. I was quite surprised when I realised that the GBS-8200 that I picked up for my MSX would work to convert the frequencies! I'd only ever expected to use it for the MSX RGB signal.

V7 VEGA 8-BIT VGA

This card (thanks, stason.org!) has the ability to output both EGA/CGA and VGA! It's 8-Bit ISA and it a little worse-for-wear...

This seems to be quite an advanced card of its era. Happily outputting to the monitor you happen to have and allowing for future upgrades! It also even seems to have the VGA auxiliary header?

VIDEO SEVEN V7 VEGA EGA

This card (thanks again to stason.org!) is a little older. It has a header for a light-pen and suppsoedly two composite video inputs!?

GBS-8200

I had purchased the bare-bones board and never tried it. Thanks to my new desktop power supply, getting it going was really very easy. The board comes with a standard DC jack, but also a pin header for the input voltage. Instead of using a crappy wall-wart, I instead powered it on the supply, having the additional benefit of knowing the current requirement!

Ian Stedman thoroughly reviewed this board. His outcome was that there were a few issues, but a strong power supply is not needed. It turns out that my testing below shows that it hardly needs 5v at 400mA!

You can see where I've soldered on to for the EGA/CGA input. It's the bottom-right 5-pin header and I couldn't find an acceptable plug. In the end, a quick bit of tinning worked. There's 4 wires: R,G,B, Sync and Ground. The EGA Pinout on Wikipedia (CGA is nearly identical) shows that there are two sync lines, but we only have one on the GBS-8200! As mentioned above, we'll use the bottom-left connector on the board.

Combining HSync and VSync

We'll need to combine the Horizontal and Vertical Sync outputs from the EGA signal as the GBS-8200 requires a single Composite Sync signal. To do this, we can use an XOR or OR gate. Ian is our saviour once again and has provided a circuit to combine the signals.

Build the circuit as he's described. I actually found that either XOR or OR worked fine with the GBS-8200!

I probably should've tested some games...

Hercules?

No such love. Same connector, but a very different video signal. Turns out it's actually a digital TTL signal that this unit cannot process. If you really want yo convert it then you'll need to buy a GBS8219.

Is that a printer port? Space saving tech! I don't have any plans to pay for a Hercules monitor or an 8219, so this is going straight on eBay.
