TI-5025 looks curious too, it's like a 0980 but the output PLA differs.

D'oh!

I got the TI-5025 on accident. I won an auction for a TI 5050M, which uses a TMS1100, but was sent the 5025 instead. The 5025 has a VFD and built-in printer.

I'm not sure what game or device that chip is from. We have another intact M32018 masked chip if anyone wants to probe it some...

That's the one that Kevtris sent to the Visual 6502 guys. I transcribed the bits and ran it in my little TMS1000 emulator, but didn't figure out what it did. Could be a game - some of the Microvision carts have 5 digits, and Cosmic Hunter is labeled M34017. Or it could be a microwave oven controller smile I uploaded the ROM dump, but it might have some bit errors. It's harder to check because the only pictures are of the top metal layer. http://www.seanriddle.com/tms1000.html

I feel dumb- I thought SnS was all figured out. I'll see if I can get one for not too much dough.

I didn't see K1/2/4/8/3 in your 0980 hw descriptions, so, FYI here they are for ti30 and tiprog (probably others too).
// pin 10 k1
// pin 9 k2
// pin 8 k4
// pin 7 k8
// pin 6 k3

TI0980 emulation is pretty much working here. The algorithm to convert the raw dumps to 0980 is still valid, except for this line:
int mypage=page; // TODO/verify
change it to this:
int mypage=(page<8)?(page^7):page;

And by the way, do you have a die pic for that TMS1100 Star Wars game? The dump should be correct, but we don't have the PLAs.

Lord Nightmare: mayhaps Speak & Spell mcu core is the same one TI-5025. That one has loads of output PLA terms. **edit**: 32 terms, "0262C, T 0260A" marked on die

see pic on sean's site, on this page http://www.seanriddle.com/ticalcs.html

Great!

TI30, Programmer and Business Analyst I all use the same PCB, so their pinouts should be identical.

So the page "reversal" is different from the other chips, huh? The TMS1000, 1100 and 0970 pages are arranged 0-7 then 15-8.

Can you upload or email me one of the ROM dumps that you have reordered properly?

All I can find is a top metal shot of Star Wars: http://www.seanriddle.com/mp3438a_rough_2k.jpg

I'll see if I've got a full post-acid scan that I can assemble. If not, I'll probably just shoot the instruction and output PLAs.

I'm *guessing* the tms0260 is the immediate predecessor of the speak and spell MCU which is tmc0270 (well, ti numbered the first few masks of each chip by incrementing the last digit i.e. tmc0271 tmc0272, tmc0274 etc, though later chips are tmc0270-xyz)

Got it, thanks! I updated my converter program to match. I found 2 bits in TI Programmer that were obscured by dirt: $3CB from $81 to $A1 and $3EF from $03 to $13.

I decapped the Amaze-A-Tron TMS1100 but the top metal layer is pretty dirty, so I'm going to try to clean it in H2SO4 to get a nicer pic before using Whink to remove the metal.

I uploaded the Star Wars Battle Command instruction and output PLAs: http://www.seanriddle.com/tms1100.html

Ok, Starwars microinstructions are the same as standard TMS1100, just in a slightly different order. (kinda same case as Simon)
