TMS1470 would be 28 pins; that's what was in the Astro.

Any scans of the back of the PCB? Seeing what connects where might help.

I stand corrected- in an interesting coincidence, I got 2 Entex card games today; Electronic Poker and Black Jack / Gin Rummy. They are essentially the same hardware; an 11-digit 8-segment VFD with symbols for the 4 suits around each digit, and a 40-pin TI SDIP. I torched one open and it's a TMS-1400 (probably actually a 1470, since the games have VFDs). I'll post more info later.

Edit: I guess technically the 40-pin VFD version is the TMS1670, but the die is labeled TMS1400.

Entex Jackpot Gin Rummy Black Jack has a TMS-1670 labeled
MPF553
MHL ^ 8027

Entex Electronic Poker has a TMS-1370 labeled
MP2105
MSHL ^ 7940

Both PCBs are marked Gakken.

I also got a TI-1000 with a TMS-1990 labeled
TMC1991NL
ATP 7736

and I cleaned the other TMS-1990 die.

Unfortunately, the 8-pin DIP from Plus One is a COP410, so I don't think I'll be able to see the ROM bits.

ah nice, was wondering what was in those entex card game... games. Surprisingly it's got that much horsepower in there, though they probably need it for the RAM to store the card deck.

Yes, gakken made a few of entex's games. Gakken actually made tons of handheld VFD games for various manufacturers, like those coleco tabletop games- but their name does not show up anywhere on the boards. The pac-man/ ms pac coleco tabletops are made by Gakken too and Gakken even released pac-man as their own game with very minor changes, in the same cabinet.

oh didn't see what you said about plus one. That's really freaky that they have a COP410 in there! I wonder how they tested it? must've tested the dice, packaged them up, and hoped for the best. Does it have enough pads for 20 pins or whatever?

Do you have the pictures? I'd like to compare with the game&watch, which is somewhere between the sm3903 and the sm510.

It seems like he's having trouble registering on bannister forum. He also says that Entex Hip Pocket Baseball is not an MCU.

not MP7553?

TMS13xx/16xx are not emulated yet at all smile It'll be interesting to see what they changed this time.

Quick question: on TMS1990, do you know which pad(as visible on die edge) goes to which pin?

Mark- it looks just like the die on the Funtronics Jacks PCB. I'll post some pics soon. The game is pretty simple, so they may have just tested its functionality, instead of verifying the ROM contents.

OG- I'll post a much better die shot of Top Gun minus the top metal layer.

Hap- I just noticed that I don't have any pinouts for the TMS1600 - and where did we get the pinouts for the TMS1400? Did we just figure them out by PCB wiring and code? Was there info in a patent?

I did a quick compare of that pachinko PCB to the 2 Entex card games but I'm unable to give you an answer yet. I see some similarities to the 1670 and some to the 1370, but I also see differences.
