Does anyone have the "Unibug" ROM that was supplied with the TI
TM990/189 University Board? This was an educational and evaluation
board for the TMS9980 microprocessor, an 8-bit-bus version of the TMS9900.
It's not hard to find images of the "University BASIC" ROMs on the net.
Those ROMs replaced the Unibug ROM.
Thanks,
Eric

I have a 990/189 with a single TMS4732 4KB ROM installed. Is there an
obvious way to know if that's the one you want? I could probably dump it's
contents without too much trouble.

If it displays "CPU READY" after power-up, it's the right one.
In addition to the image, it would be useful to know what the markings
on the chip are, or to have a photo in which they can be seen.
If you have the optional serial port on the board, you could dump the
ROM over the serial port without removing it from the board.
Thanks!

Another fun thing you can add to this kit (if you can find it) is the Erying Research
color graphics board. its the same graphics chip in the 99/4
The TI manual set was great, huge binder and it was a very good course on microprocessors,
I really enjoyed mine!

I have a 9900 eval board a friend did himself, I'll take a look at it.
I would probably have to get it to you, as I don't have copying capability.

Unibug ROM dump sent to Eric offlist. I can send this to anyone else that
wants it before Eric contributes this somewhere public.
