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

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

Both PCBs are marked Gakken.

I also got a TI-1000 with a TMS-1990 labeled
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.
