I wanted to reactivate a TI Professional Computer
(TIPC) and all I get
some seconds after powering it on is the message
"** system error ** 0004"
and a beep, lasting for about 2 seconds.
The TIPC is an early, not really compatible clone of the IBM PC 5150. I
wonder if I need to do some reengineering and/or disassembling or if
there is a service manual out there.
I didn't find them in the technical reference but did find a list in the
bios listing. If I read that correctly its interrupt or timers failed.
Should be LED ON OFF OFF.
I had one as part of my vintage computer exhibit.

I had started to put some stuff online. So far I have the disks that we got
from the local TI usergroup.
