A 66mhz PPC603 BeBox!

Never, in my wildest fantasies, would I have thought I'd be the owner of one of these! Of course, caveats-be-caveats: it was listed as non-working and needing-work. How much work would it actually need?

First thing's first... a proper source of information was required. Thankfully, The BeBox Zone has been recorded by the web.archive in all of its glory!

Which revision?

Prior to receiving the unit, I asked which Revision it was, just so that I could get ahead of any problems. Turns out these machines had quite a lengthy Revision history and, well, I could be in for a lot of pain. For even more information, here's a great page with information on the differening revisions. Also, if I was to receive an earlier revision than v6, here's what happens when you try to upgrade a Rev.05?. Fortunately, the answer came back that it was to be a Revision 6! This meant any BeOS would work on it... as long as the CPUs could hold out.

Video Card?

The author had mentioned that the machine probably needed RAM and a new video card. I started googling and found a lot of conflictcing information... or just information that only pertained to newer x86 BeOS versions. Fortunately, if you go way back, there's a cache of the old Be site here with a list of the valid hardware for the BeBox! The good cards listed are:

• Cirrus Alpine 5434
• STB Systems Nitro PCI 1.5 (5434)
• Cirrus J6NGD543XPCI (5434)
• Number Nine GXE64 (864)
• Diamond Stealth 64 DRAM T PCI (Trio64)
• Expert Color Trio64 PCI

Now, I'm sure that newer/cooler video cards are supported for BeOS, so I'm thinking this page is dated somewhere around BeOS 3.0? It's listed as 1999. I also know that I had a beautiful Diamond Stealth in the junk box last year and sold it. What was I possibly going to use it for?!

So, actually, it seems that BeOS R4.5 was the last known good OS for this model of BeBox. What cards does it support OOTB? There's a hardware compatibility list here, and it's sad to see that's the last version of the page... seems the domain expired not long after! Here's the PPC-specific notes which then points to a Q&A URL for the BeBox that was never captured. But, slapping that into Google brings back the original page... and we complete a loop as it's the same link as the first one above!

Based on list above, I managed to source a Diamond Stealth in PCI format, prior to even receiving the BeBox!

Sound Card?

You don't need to worry about sound as it's all on-board. There's even an internal speaker, just like any good Macintosh.

RAM?

You'll find the requirements here, but the basic idea is 60nz 72-pin non-parity. Parity will work, but the parity function won't be employed. Sizes can be mixed and matched in pairs.

The author mentioned that RAM might be an issue, so I also purchased a few matching-sticks in advance.

Network Card?

There was no mention of an included network card, so I started googlin'. Looks like I'd need an NE2000 compatible ISA card. The other alternative is the DEC 21040/21041 on PCI. You'll find 3Com 3C509 drivers over here. I just don't have one of those cards anymore... yes... I sold one last year also! I really think I'll be able to install an RTL8139 ... but the bebits archive only has a version for Intel.

Reviewing other people's problems...

Just because there was time... and that this is a very vintage machine... and that google returns some quickly-damning results, I fell down the rabbit hole of other user's tales of woe. Not to be discouraged, it's great to read through such articles to understand what I might have been in for?

Pick-up day!

This is all in hind-sight, so I need to come clean. I was visiting Canberra to see my grandfather in hospital. It was the first weekend I was there that I also arranged to pick up this unit, and, call it bittersweet timing, but it was serendipitous that I grabbed this and got to say goodbyes. I can't word this well, but there was extra value added to the unit.

It even came in the original box!? Pretty rotten, but a great momento! Would you believe I never took a pic of the whole unit fresh outta the box? Instead, I delved straight into the issues...

Being away-from-home, a quick inspection was really all that I could do. The whole unit was in amazing condition! The only real physically-obvious issue was the "jack nuts" (as I now find they're called) on the ports on the rear and they were quickly replaced.

I take that back... not so quickly..

And then...

Only needing a little bit of extra effort!

Powering the beast on!

So, I got back to Melbourne and gave it a once-over. All checked out, so I slapped in a power cable and hit the switch on the rear. Fans spun up, HDDs also, but no life. Thanks to the previously-received RAM, I swapped out the existing two SIMMs with another pair. Before long... we had POST!

What? It just works? There was no video output on my shitty little VGA LCD, so I plugged in my nearest Trinitron. Whatttttttt.....

I had no input devices... so I just hit the switch with a STUPID grin on my face.

Upgrading BeOS

I grabbed a 3.2 BeOS BOOT ROM UPGRADE from some random site and wrote it to a floppy... which booted!

From there, I skipped ahead to BeOS 4.5, as I'd bought the box back in 1999 with two other friends from The Software Shop in Phillip, ACT.

The floppy was useless, but holding down spacebar let me get the boot menu...

And yes, the CD was visible, and even booted!

Such a familiar screen! A spare SCSI HDD was inserted to install 4.5 onto. This required the removal of two screws, allowing access to the tray...

Haha... you should've heard the noise when power was applied to that revolting Apple SCSI HDD. It was quickly replaced. Note that this unit also has an IDE bus, so I can easily upgrade to larger disks in the future... and proper burners!

Time to tinker...

Networking...

The OS installed in no time and rebooted to a familiar desktop. The unit came with an RTL8139 ISA card which happily worked as an ISA NE2000?

And I could ping away!

What's next?

DOOM is next. WON, from the experimental folder, failed to find my AFP and SAMBA shares, so I need to find a proper SMB client from somewhere. All links are turning up 404 so far. Sheepshaver also needs to go on there with a captive version of Mac OS 8.5. This page also hints at other software I should install.

NEC PC-9801VX – SCSI Devices

So, I've gotten my PC-9801VX to power-on, boot a floppy disk and then initialise the 486 upgrade... the next step was to get a HDD attached. Luckily, the unit already came with both SASI and SCSI cards, so I just had to choose one and connect things. SCSI was chosen, as I don't even know what SASI is and, perfectly by chance, I'd purchased an external 4.3gb SCSI HDD with the matching HD50 plugs!

Upon searching the usual boxes'o'junk for a cable, I attempted to plug the unit in and, to my surprise, the connector on the SCSI card wasn't actually HD50.

Turns out it's a mini-centronics HPCN50! You can learn all about SCSI connectors over here. It seems this connector type is very popular amongst PC98s. With this new information, I went scouring the web for an adapter. I found one from my usual favourite seller in NSW (RetroShopBox on eBay) and then also another full SCSI cable (HPCN50 to HD50) from the UK... but that was to take a lot longer to arrive.

I adjusted the HDD to SCSI ID 0 and, with everything connected, booted the IPL disk and then MS-DOS 6.20 Disk #1. The installation was painless, thanks to the Gotek, and before long the machine rebooted and failed miserably. This was due to MS-DOS 6.20 trying to start without the 486 Accelerator initialised and so I rebooted and installed that via the Installation disk. Before long, the machine had rebooted into DOSSHELL!

Removable Media

I grabbed my nearest Magneto-Optical drive and chained it onto the SCSI bus. It happened to be set to ID 6 and I just left it as-is and attempted to boot. Before long it threw the following error:

No system files!

To add insult to injury, it just continued to emit a high pitched squeal. Seems it thinks/knows this is a removable drive and expects removable media to be bootable. The disk in there certainly wasn't... I didn't even know what was on it.

Just for fun, I slapped in the IPL disk, installed DOS, installed the accelerator and then voila!, the disk started booting.. But the fun didn't last long. It failed with an error initialising MSDOS.SYS? How does that even fail?

No matter of mucking around got me further... Until I switched the MO's SCSI ID from 6 to 1. I had no idea why, but on ID 1, the MO booted to a command prompt! Unfortunately, once booted, I couldn't get to the internal HDD. The MO was mounted as drive A: and the floppies were mounted straight afterwards. No HDDs to be seen.

I had initially expected this unit to show up as a second HDD, so was a little perplexed as to how to make it act as one. A few emails back and forth from Adachi-san saw me realise that I either had to configure the drive into HDD mode, or force the SCSI controller to treat it like a HDD.

The SCSI controller is a TEXA HA55-BSW and, whilst booting, there's an initialisation screen that shows the devices found on IDs. During this process, there's no hint that it's able to be configured. After a little bit of googling, it turns out it can be configured, but only if you hold down the T and S keys at the same time whilst it's initialising.

Inside the configuration menu, you'll find drive options in the second choice. From here you can tick through the IDs and set the parameters accordingly.

I happened to find that the drive type could be set to MO Small Image and, well, this worked! I now got to the SCSI boot menu instead of just booting directly from the MO.

From here I booted into DOS on the main HDD at SCSI ID 0, but I still could only see that HDD (and other partitions on that SCSI drive), and no other SCSI devices. After a few more emails, it turns out there's a requirement with PC98 SCSI IDs: they need to be consecutive! That explained the issue above with MSDOS.SYS, but not this new one. Adachi-san also passed me a formatter that could format 230mb MOs up to 218mb and I went for it. Actually, it was obvious that the format was wrong as this is how the MO showed in the SCSI boot menu:

Similar to USB keys of nowadays with multiple partitions, this MO has been partitioned+formatted in "removable mode" and therefore shows up corruptly in HD mode. I re-partitioned and re-formatted the drive in the current HD mode with (RMUTL (Now MOUTL) from Adachi-san, received 218mb free and drive C appeared! Yesssss...... We can now copy from MO to HDD.

Thanks to my MO USB drive on my main machine, I could start expanding HDI files onto MOs and tinker...

CD-ROMs

I thought I might have needed the latest CD Drivers from archive.org, but DOS 6.20 just installed NECCDB.SYS and MSCDEX.EXE and my SCSI CD drive was mounted! I could even list the contents of the CD in the drive! Looking more-closely, it's actually an NEC CD-3010A which is somehow covered by the driver installed. Note that upon installation, DOS copies the driver it wants to use to the DOS folder as NECCD.SYS. Just match the sizes to determine which one it's actually using.

The Final SCSI Stack

Somehow I had enough cables, with the correct SCSI connectors, to join all of these together and terminate them!

It all works perfectly and I'm actually really impressed with the tech-level of multiple-booting and boot-menu of my PC-9801VX.

NEC PC-9801VX – PK-X486 CPU Upgrade

So, this PC-9801VX came with the weird sticker on the front indicating that it was powered by a 486 CPU.

It was a pretty random claim seeing as that the base system is built from a 286. How could you possibly upgrade an 8-bit CPU to 32-bit?

A quick inspection (see the over here) saw that the 486 was contained on a daughter board which used a PLCC-socket adapter to hijack the 286 socket!

The upgrade happens to be an IO-DATA PK-X486/87SLS (IOD2Y284), consisting of a Texas Instruments TX486SLC 25mhz CPU coupled with a Cyrix FastMath CX-83387 33mhz 387 Math Coprocessor.

As that this CPU actually replaces the existing 286, it's always been active and operating the system but, regardless of this fact, the system still reports as a 286!

Trying to install DOS 6.20 very quickly throws a "You cannot install DOS 6.20 on a machine with a 286 Processor."

So, a little googling later and it turns out there's a TSR which needs to be loaded. That link indicates the TSR is named PK486.COM, but no amount of googling resulted in such a file. Instead, PK486D.COM showed better results, like this Interrupt Extender for this CPU Upgrade, but that software still didn't include the TSR!

Finally, a little more googling brought up this Japanese forum post indicating that there was an old oldsoft/98.htm page at the IODATA website that had derelique drivers. Of course, this page no longer existed, so web.archive.org to the rescue! Finally, there it is, down the bottom of the page.

Unfortunately, the files are just upgrades and want the original setup disk to hack some bytes. So, next up I started clicking random links on the iodata library site and found this page. It's full of random Win95 stuff, but one file seemed to be valid for a newer upgrade card than I had.

The COM files looked great... so I just renamed and executed... and the CPUCHK.COM even threw out the following result...

But, alas, both TSRs just reported an incorrect CPU when trying to run. Of course, what are the chances they'd even work.

UPDATE:: Adachi-san of Adachi Giken has come to the rescue! You can skip this part.

IF ANYONE HAS ONE OF THESE UPGRADE KITS, CAN THEY PLEASE MAKE AN IMAGE OF THE DISKS FOR THE INTERNET?... there's many sites with people asking for the software and I'd love to try it out! The box looks like this... and the disks seem to come in both 5.25 and 3.5" variants.

The disks are labelled "共通サポートソフト".

Excuse the image quality... they were flogged from a yahoo auction. But here's a better close-up...

I'll have to keep watching the auctions as those Power Up Kit /PK-X486Sシリーズ disks above went for $10.

The disks!

So, the kit comes with two disks: an IPL and an Installation disk. The IPL (or Initial Program Loader) is used to boot the machine into a state where the seconday CPU is active. This is good to use prior to installation of something that needs a 386+ (i.e. DOS 6.20), so boot this disk to the following prompt:

And then swap disks. Once done, hit enter and you'll get to continue as if you booted the second disk you inserted, but on a 486! Of course, after installation, rebooting the machine will set the 286 active again and that's where the Installation disk comes in. Let the machine restart after installing DOS 6.20 and watch it crash and burn. Once it does that, insert the Installation disk and restart the machine...

That screen above scrolls onto the screen in 90s goodness... and then you get the main menu. The options are to Backup something, read the README, install the software or configure cache. Choose the third option, and then your SCSI disk.

From here, choose the partition/installation and go for it!

You'll then be told that everything is complete and that it's time to restart your machine.

With this done, your machine is now a 486! Congrats. Message me if you need the disk images.

Z Scale Layout – Akia 485-Series Traction Tyres

Just for a lesson in complete-failure, I attempted the fitting of traction tyres to an Akia 485-series EMU powered-car. The train couldn't get up gradients and so I thought I'd see how it went with traction tyres from Rokuhan.

Rokuhan provides both 4mm and 5mm tyres, and I purchased a bunch of both sizes as I know I'll need them in the future. The power car in question is a standard 485-series passenger car and the shell comes off once minimal force is applied to separate both walls from the chassis. From here, you then need to remove the top circuit board by inserting a flat-head screwdriver in the 4 holes in the chassis, two on each side.

Once that's off, remove the two weights.

It gets a little tricky from here. The bogies are attached via drive-shafts with lateral pins. The chassis is a single unit, so you actually have to spread the frame to get the bogies out. Make sure to allow space for the drive-shafts when doing this, otherwise you might snap them.

With the bogies out, you can grab a flat-head screwdriver and press down on the clips next to the power pick-ups. Pushing down on these will push the under-frame of the bogie onto the table. Once it's separated enough, you can flip the bogie over and lever the frame off.

With this finally off, you have full access to the wheelsets and you can install traction tyres.

Unfortunately, these wheelsets don't have the grooves for tyres and the trains run erratically once installed.
So don't do it! The end.
