Home Page Forums MAME MAME TMS-09xx/1xxx thread (was New Dumps)

Well I'm finally here! Sean, did you ever get the TMS1xxx chips to dump electrically? I don't know if I heard if you did or not.

If we can get a better die shot, I might be able to poke around on the TMS1400 to see if I can figure out how to electrically dump it vs. the blowtorch and typing method.

I successfully used the die shot for the NEC D650 to figure out how to electrically dump it, which is how I got the D552/3 dumps for emulating 4 different VFD games.

Turns out a similar method worked on the HD38800/HD38820/HD38750. I actually found factory test code in these parts which I then used to properly dump every bank including the "pattern ROM".
