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. http://blog.kevtris.org/blogfiles/Handhelds/LED%20and%20Sound%20Only%20Games/Castle%20Tactix/

Tactix pinout: My browser cache reminded me it's already online: http://www.seanriddle.com/tactix.txtkevtris: uPD557 has 2KB internal ROM, your file is 1KB. Was the 2nd half filled with 00s?

Yes, modifications to the microinstructions PLA are more common on TMS1000(SR16) and TMS0970. Touch & Tell looks like it changed much more. Here's some just from the 1st page of the patent, I think it's a bit too much to be able to construct a correct PLA. Maybe you can decap one if you find a one cheap?
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: www.seanriddle.com/cd8012instpla.jpgwww.seanriddle.com/cd8012opla.jpg

The microinstructions differ a lot from default indeed, I think it's the same one as the one in patent. see: http://pastebin.com/9UH9QhEM

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  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)
