Texas Instruments Portable Professional Computer - Multifunction Board Installation Manual

[hanshuebner]

Hi,

I have a Texas Instruments Portable Professional Computer on my bench for repair and upgrade. Together with the unit, I received a couple of Multifunction Boards (#2245876) with memory and clock (no serial or parallel daughter cards, sadly):



Amazingly, two of the boards still have 3.4V coming out of their batteries.

There is also a memory upgrade daughter board (256K Secondary Multi-Function Kit, #2245895):



Most of the boards have some failed memory chips and I'm looking forward to putting all of them into sockets. I have not found a manual or a driver disk image, however, so I would not know how to test the clock functionality. Also, maybe some jumpers need to be set for the 256k expansion to be recognized, so a manual would be most helpful. Can anyone help me out?

Thank you!
Hans

Not trying to dissuade you, but you do realize TIPC's (including even the portables) weren't IBM compatible, right? They required software specifically written for TIPC's. I owned several of them along with the Business Pros at one point many years ago (I worked for a Siemens facility that had previously been owned by TI). Only one (a desktop TIPC) had been made IBM compatible (a nearly complete motherboard upgrade to a 286). All those machines are long gone (I may have a portable here somewhere), but finding any documentation on them now would take a Herculean effort. You might have a little better luck posting in the TI forum.

@T-R-A I'm really just trying to get the machine into working order as well as possible. It is lacking the graphics option, so many of the demos that are available online are not working on it anyway. What's the TI forum that you're mentioning?
