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

sure, send. I will poke around on the MN stuff tonight

Just looked. the 40 pin version of the MN14xx parts definitely have a test pin... the 28 pin version, I don't know. I can't find a datasheet with the pinout for the 28 pin version, just the 40 pin one. the MN1405 is 40 pins, while the 1400 can be 28 or 40.

http://www.semicon.panasonic.co.jp/ds4/MN1400_series__J_discon.pdf shows the 28-pin version of the 1400 (slightly different pinout from the 1402). The 1400 in Perfection has 28-pins; my die shot shows 12 un-bonded pads, so it's easy to figure out the numbering.

Even the 16-pin MN1404 has a TST pin! And it only has 6 outputs (CO0-CO5, which I think are strobes, so normally only one active at a time).

ah nice datasheet. the ones I found had the instruction set and bit mappings so once the ROM is extracted getting it to run should be pretty simple. Not sure how the test pin works, but I wouldn't be too surprised if it's similar to how the 55x/650/HD388xx work.

I uploaded info on the TI Little Professor 1982 that Hap sent:

I need to scan the LCD.

Update on known tsp50cxx chips:
1. Keynote speech synthesizer module that Kevtris has ("2472JXT // CSM10075AN")
2. MB Electronic Talking Battleship(1989)[Oct 92] ("2234673 // BATTLESHIP // CSM10017AN")
3. MB Electronic Talking Battleship(1989)[Apr 96] ("5BATX6T // BATTLESHIP-2 // CSM10259AN")
4. MB Electronic Talking Battleship(1989)[? 98 or 99] ("85AX02T // B-SHIP 1998 // CSM10287AN")
5. MB Dream Phone(1991) ("5507 JKT // DREAM PHONE2 // CSM11120AN")
6. Echo II Speech Synthesizer Card for Apple2 (1989) ("ECHO-2 SEC // LU 9020 // 25954 PHILIPPINES") [note this uses a different, earlier tsp50c01 or 02 or other part(probably 02 given the '25954' number starts with 2) with a slightly different pinout to tsp50c10]
7. MB Omega Virus(1992) ("3253ACT // OMEGA VIRUS // CSM11161AN")
8. Mystery Vtech unit from Dumping Union ("84C91HT // VIDEO TECH // CSM10150AN")
we suspect that MB Mall Madness also uses a tsp50cxx but don't have the chip label yet.
Also from Boardgamegeek forums we know a German voice version of Omega Virus exists as well.

What we know about the tsp50cxx marking numbers:
First line:
First digit is almost certainly the last digit of the manufacturing year. Unclear what the rest is.
Second line: Product name, if present.
Third Line: "CSM", then "10" for tsp50c10 or "11" for tsp50c11, then 3-digit mask code, then 'as a whole series' silicon stepping revision (usually "A") and "N" for plastic package.

Unclear what changed between the 3 revisions of Talking battleship. LN owns one of the '10 92' made boards, Zorix owns a '4 96' made one. Sean owns a 1998 one but the MCU has been decapped already and didn't seem readable optically, so we could use another 1998 one if possible.

There is almost certainly a way to digitally dump these chips, the databook may hold some clues: http://www.ti.com/lit/ml/spss011d/spss011d.pdf

I uploaded info on Tomy Pinball and Mattel Dungeons and Dragons Computer Labyrinth Game: http://www.seanriddle.com/tms1100.html

For lprof82, do you have higher resolution photos of the PLAs? I see the output PLA on the left, with a bit of LCD RAM(?), and main instruction line select + microinstructions on the middle and right.

I'll post some more pics of the lprof82 die.

I corrected a couple of bits on both Tomy Pinball and Mattel D&D, so get the new binary files!

<edit>
There's so much different on the CD4570 die that I uploaded giant pics of the full die before and after removing the top metal layer:

They are both about 26 MB. It's icy here, so my internet connection is slow today, so it might take a while to download them.

Got them, thanks. I'll do the TMS1100 ones first.
