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

Good to hear, Sean. Is there any sort of list for wanted TMS chips (or other microcontrollers)? You might find some interesting items on this page:

I don't know that I have any more TMS chips. I do have a few old handhelds, like Mattel Auto Race, which is a really early electronic game. Here is an interesting interview with the programmer:

hap, I know that the Mathemagician had overlays for various games. I'm not sure exactly how it worked, though.

Incog had some overlays. I haven't seen him on here lately, but I'll try to get in touch to see if he can re-upload them.

As for Speak & Spell hardware. I should be able to get the CPU core in MESS working to support TMC0270. But I think improving the speech chip emulation is not in my alley of expertise, more for Lord Nightmare and maybe couriersud.

I typed in the Speak & Math ROM from patent 4946391, both the HEX codes and the source code (I can be nearly certain the type-in is correct by verifying it with a quick assembler tool i wrote)

ranger_lennier yes I know about the overlays, scans should be useful for MAME Artwork.

'wanted' TMS1000 chips, hmmmmm. Personally I'm glad with the TI-30, already decapped. If I look around online, "Master Merlin" and "Split Second" by Parker Brothers sound like fun. As well as TI's "Little Professor".

I've been told that Mattel Auto Race has a Rockwell PPS4. Same for Missile Attack (which was decapped by Sean?? - any idea how to interpret the ROM?)

Cool, thanks! I will let you know in this topic when APF Mathemagician emulation is finished (should be very soon if I don't encounter problems)

Wow, that's really complete collection. Thanks for sharing!

I don't know about the ROM layout for Auto Race, but the interview says it only has 511 bytes of ROM. Does anyone know of a smaller game than that?

Paul Robson sent me the Battle Star Galactica Space Alert game- it has a Rockwell B6001, which is a modified calculator chip. I made a pretty nice die shot from it, but we could never find any documentation on the processor, so we didn't know where to start on the ROM dump or how to interpret it if we did. He even contacted the original programmer, but didn't get much info. There is a Rockwell patent (US4339134) with code for a calculator/blackjack game that probably uses a similar processor.

BSG:SA also only has a 512-byte ROM. My understanding of the 511-byte size is that the processor uses an LFSR like the TMS-1x00 chips, but doesn't have the extra circuitry to handle the all 1's state, so one byte can't be accessed. The Sharp SM51x processors are similar. TI must have had a patent on accessing the extra byte.

I frankensteined a working S&S from the two that I got, using the PCB with the older chips. It definitely has the "no module bug". I pulled all the chips from the other PCB. I was hoping they'd have some further ID numbers on the bottom, but they do not. A couple of them do have different die revisions than the other chips- the "newer" ones are TMC0271NL NBS 7910, TMC0351NL NBU 7906, TMC0352NL DAU 7901, TMC0281NL D 7906. The "older" ones are TMC0271NL DBS 7832, TMC0351NL DBU 7832, TMC0352NL DAU 7832, TMC0281NL D 7832.

I'll dump the ROMs, then decap the 4 chips from the broken board.

here's the APF Mathemagician driver: http://git.redump.net/mame/tree/src/mess/drivers/mathmagi.c

tandy12 is next, hmm

That was fast, hap!

Does anyone know what the Blackjack game was released as, or if it even was released?
