From what I can see it appears to be a TI professional computer, But it is a development version. Is there a history of any of these? Sold or in a collection? I have not opened it up or attempted to power on yet.

What the rest of it look like? Any other markings on it?From what I can see it appears to be a TI professional computer, But it is a development version. Is there a history of any of these? Sold or in a collection? I have not opened it up or attempted to power on yet.
That was our first computer and I still have it. Haven't seen development version before.From what I can see it appears to be a TI professional computer, But it is a development version.

That is not the monitor that I got with it. I will take more pictures when I get home.That was our first computer and I still have it. Haven't seen development version before.

Mine had RIFA caps in the power supply that did the expected smoke screen. Its an MS-DOS computer but not that compatible with IBM PC. Uses monitor with higher horizontal frequency. I think around 17 khz. The monitor behind it doesn't look like either the monochrome or color monitor TI sold.
There are no other markings on it, The only information on it is that it belonged to an engineer that worked at TIWhat the rest of it look like? Any other markings on it?

Pegasus was the internal name for the computer. The motherboard is labeled PEGASUS MOTHERBOARD in production machines.So, unless more is known about this "Pegasus Engineering" designation, it may or may not be special.
I'd be interested to know what software is installed on that disk. I've been looking for the TIPC DNIO package (I think this was also known as Business System Communications or similar.) The disk should be dumped and the image archived, regardless.I'd try a slow warm up on a variac, sniff for smoke. It's likely to just work. If it's a prototype running unlicensed DOS you have a rare find. Post yr findings.
Cool. Was it IBM out-marketed TI, or was it not TI?My dad, Richard Tarrant, was an engineer on the 'Pegasus' project, the internal code name for the TI PC. They had a group in Richardson, some were veterans of the 99/4A., etc. (Dad designed the disk expansion unit for the 99/4A.) One fun story from the Pegasus project was their meeting with a young Bill Gates to license DOS. Pegasus could have been the first PC.. but IBM out-marketed TI.
