Stuart Posted May 23, 2012 Share Posted May 23, 2012 Does anyone have, or know anything about, TMS9900 chips with the additional marking "MP9514". It will probably be a ceramic chip with a gold top. I've been contacted by a chap who's after one to repair some equipment. Apparently it's not interchangeable with the standard TMS9900 chip (although its still 64-pin, 0.6" wide). I seem to recall that the MP number relates to a mask number so its probably different internally somehow. Stuart. Quote Link to comment Share on other sites More sharing options...
matthew180 Posted May 23, 2012 Share Posted May 23, 2012 If Google does not turn up something, good luck finding any "offline" info. Someone would have to have the old datasheet or something. I have to imagine sourcing one will be even harder. If the differences were known, it might be possible to modify a standard 9900 to work?
