I redid my handhelds directory to categorize things better. So no, it didn't disappear, it just got rearranged a bit.

I also dumped the UPD557LC from "tactix" that sean sent me. So that's now sitting here:

He will be along shortly to post the text file on pinout I suspect.

Tactix pinout: My browser cache reminded me it's already online:
http://www.seanriddle.com/tactix.txt

kevtris: uPD557 has 2KB internal ROM, your file is 1KB. Was the 2nd half filled with 00s?

Thanks, Kevin!

default 1100 -> touch n tell

03: XMA -> TAM
3E: IMAC -> XMA
3C: SAMAN -> DCY
01: ALEM -> YNEA

Winbond? I don't think we emulate any of them in MAME.

I decapped the CD8012 chip from Touch & Tell. I don't have the full die shots yet, but here are the instruction and output PLAs:

The microinstructions differ a lot from default indeed, I think it's the same one as the one in patent.

blah, I must've uploaded the wrong file. I did dump it as 2K and confirmed the code looked good in it. I dumped it as both because originally I didn't know how big it was.

The bin is updated and should now be 2K.

I put almost all of my games back together now over the last 2 days and so far all of them work. Had to fix a few that had corroded battery contacts and such but all of them seem to have lived through it so far.

Hey guys, the saturn SMPC (peripheral controller) is a hitachi unidentified 4-bit cpu with a test pin. Think you can give it your love?

http://www.db-elec.com/home/technical-info/saturn/schematics has the schematics showing the pinout, the fact that it's a 4-bitter is in the saturn docs (and we all know that sega docs are always perfectly correct).

OG.

kevtris, yeah I noticed that the disasm was from a 2KB file, and then converted that one to a rom file wink
Could you measure the MCU OSCs now that the games are working again?

OG: it doesn't match any HMCS40 pinout. Maybe a HMCS400 one, or did Hitachi make more 4-bit MCUs? (I only know the ones from the 1980s)
