That qualifies as a "one off", right? I mean, it's PowerPC, but not Mac.

I just posted a video of mine booting, because I happened to find on YouTube exactly two videos detailing "Windows NT on a PowerPC!"

Both of which are horrendous-quality (think cell-phone or webcam) videos of someone running Windows NT on a Mac, within VirtualPC (or similar.) So I decided to post my video of a PowerPC natively booting Windows NT.

And, yes, that's a PowerCD sitting next to it. The internal optical drive is dead, so I use the PowerCD. The ThinkPad has the HD50 SCSI connector, and my only HD50 cable goes from that to the wide-centronics, so I can't use either of my other portable CD-ROM drives, because one uses high-density SCSI itself (I don't have an HD-to-HD cable,) and the other uses a custom connector, with a custom cable that goes straight to Apple HDI-30 SCSI.

For my next act, I plan on installing OS/2 PowerPC Edition on it. I have a disc, but for some reason it won't boot, when from what I can find, it should be bootable. (Yes, I've verified that the disc is readable in the PowerCD drive.)

Sure, why not!

Will these run PPC Linux distros? That might be slow, but probably more useful than NT or OS/2. Though for novelty, those two operating systems are definitely interesting in their own right.

I wonder if you could get Darwin loaded on that ThinkPad...

Peace,
Drew

Power to the PowerPC!

It will run BSD for certain, I think I read that it will run a Linux as well.

Darwin would be interesting. The problem is that this is an old "PrEP" machine, and everyone had switched to "CHRP" by the time OS X was even a glint in Apple's eye. (aka: well before Apple bought NeXT.) So I really doubt anyone bothered to port Darwin to PrEP.

Yeah, a quick check shows that apparently Darwin only runs on G3 or newer on the PPC side.

Oh, and to answer some questions:

This has a 603e, 100 MHz, and a 640x480 screen; which makes it roughly equivalent to a PowerBook 5300c.

The four OSes that were offered for it by IBM were AIX, Windows NT, OS/2 PowerPC Edition, and Solaris PowerPC. At launch, AIX and Windows NT 3.51 were the only options. Windows NT 4.0 came later. OS/2 PPC and Solaris were only released after the "Power Series" line was discontinued, and both are fairly incomplete.

Both Windows NT and OS/2 are capable of running x86 code via emulation, but in both cases, only 16-bit Windows 3.1-era code. They can both run native 32-bit PowerPC code, but not 32-bit x86. (OS/2 is even capable of 16-bit OS/2 x86 code!)

And from what I can tell, there was no publicly available PPC software for either platform. (Which is really odd, since OS/2 PPC comes with an "Application Sampler" disc; yet it appears that none of the included samples ever saw the final software actually released.)
