Quirks
- The motherboard is labeled Firepower Systems, Inc. instead of Motorola.
- When the system was first powered on, it booted enough to give a "no RAM" beep. Later attempts did not give a beep. There are four diagnostic LEDs on the board labeled A, B, C, D. When booting with RAM, light A stays on. When booting with no RAM, light C stays on. When booting with no processor card, no lights stay on. The beep no longer happens. Purple believes this may be due to the capacitors no longer being able to function properly and only managed to work for the initial power-on before becoming useless for further attempts.
- After recapping, we discovered that when COMM 1 is attached to serial at 19200 baud, the system prints "AbcdefgBCD", first the first seven characters, then a pause, then the last three. Sometimes, it gets to "AbcdefgBCDE" after a second pause. Sometimes, there is a garbage character instead of this 'E'. Our hypothesis after this was that the machine doesn't like non-ECC RAM.
- After installing two sticks of EDO ECC 60ns RAM, the machine finally boots.
- The machine cannot be run without a keyboard. It will read garbage off the keyboard port and endlessly try to interpret invalid Forth commands, as seen from the serial console.
- Serial output only goes past "install-console" if no display is connected.
- Apparently the hard disk is using a beta firmware.
dev /pci/scsi@3 .propertiesoutputsv1.00 Beta 7forversion. - The registry files found on disk do not work with any of the available offline Windows NT password manipulation tools available. I had to manually find the encrypted LM hash in the registry, decrypt it, and then brute-force the original password for the Administrator account (which is: computer). See: Old-style Windows NT LM hash recovery
- If you reboot the computer from within Windows NT, when the system reboots into the firmware, it will claim to not detect a keyboard (using COM1 instead) and then hang. The Num Lock key on the keyboard stays on.
- I have not yet been able to successfully boot from the optical drive. My retail Windows NT 4.0 Workstation CD bombs out immediately in Windows Setup about not being able to load the CD-ROM device, and the device it tries to load does not change with the value of
OSLOADPARTITION. Other CDs, like for old versions of PowerPC Linux distros, don't get past the Forth interpreter regardless of how I try tobootthe files on them.
Reconstructing the boot configuration
The hard disk is configured like this:
- Partition 1: 10 MB FAT16 partition. This contains firmware-readable executables.
- Partition 2: Points to an extended partition (partition 5).
- Partition 5: NTFS partition.
Given this configuration, I was able to boot off the hard disk with the following commands:
setenv OSLOADPARTITION multi(0)scsi(0)disk(0)rdisk(0)partition(2) boot disk:,\OS\VENEER.EXE \OS\WINNT40\OSLOADER.EXE
Speculation / History
- The computer originally came from Marquette University. There is an FTP log on the hard disk with many entries for vmsb.csd.mu.edu. Additionally, the registration information in the System Properties dialog says Engineering, Marquette University. It originally had a:
- hostname of
eng142 - domain of
eng.mu.edu - static IP address of
134.48.93.142 - subnet mask of
255.255.255.0 - default gateway of
134.48.93.100 - primary DNS server of
134.48.1.32 - secondary DNS server of
134.48.1.31
- hostname of
- In response to there being an existing commercial third-party PowerPC Windows NT application on disk, Revexia says:
For the PowerPC port of NT? Wtf, I mean like I knew that was possible but I struggle to imagine why anyone would actually want to use a PPC for NT. I can think of a million purpose built NT machines that would just have been easier to use. Wonder if that university just had a bunch of expensive PPCs leftover and a mandate to transition to Windows for integration with other systems. Let us know what you figure out!
Things to archive
The disk image is "motorola.img" on the NAS.
- There is a surviving third-party commercial PowerPC Windows NT application! It is a version of something called ExecSoft Diskeeper.
- Installer for Microsoft Internet Explorer 3.01 for PowerPC
- Various hotfixes specifically for PowerPC (checked with
fileon Linux) - The copies of Veneer, OSLoader, HAL, and the drivers directory (requested by Rairii at: https://haqueers.com/@Rairii/111851384631484546)

History
- 2023-09-09: The computer is purchased at VCF Midwest. The seller states that the computer had been stored in a barn near Racine.
- 2023-09-10: The computer is temporarily transported to my parents' place.
- 2023-09-28: The computer is transported to the new home.
- 2023-12-16: 📈 The clock battery is replaced. Before replacing, it was measuring 2.9 V.
- 2023-12-16: The capacitors on multiple components are identified as bad.
- 2024-01-14: 📈 21 capacitors are replaced (8 on processor card, 13 on motherboard.
- 2024-01-24: 📈 The correct RAM is installed.
