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.

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.

That is not the monitor that I got with it. I will take more pictures when I get home.

I don't know how TI did their serial numbers, but I've seen serial number on other computers that restart at zero for special production runs. For example, a company might have ordered 100 machines but pre-loaded with a larger hard drive than normal, or special networking equipment, or such. The difference could even just be contractual, not a hardware difference. But the the computer vendor slaps on a special model number or other identifier and numbers the serials 1-100.

So, unless more is known about this "Pegasus Engineering" designation, it may or may not be special.

Pegasus was the internal name for the computer. The motherboard is labeled PEGASUS MOTHERBOARD in production machines.
