I posted the ROM pics and visual dump of the TMS1043 that LN saw on ebay: http://www.seanriddle.com/tms1040.html

I also added button info to the JR-55 page.

One of those is Tiger's Tank Attack, also looks like Afterburner is in there too. I can't find the submarine/periscope one, may have been shitcanned.

Ahh, the loose pcb that was mentioned on the shoutbox? It's from http://www.datamath.org/BASIC/TI-1200/TI-1265.htm
Do you have die pics of the instruction and output PLAs?

JR-55 is added, but locks up after initialization routine.

TMS1043 is added and working. Was the R/C osc on the PCB? And do you know the die label?

There was nothing else on the PCB but a power jack. The PCB traces look the same as on Datamath, but there aren't pads for the osc resistor/cap: www.seanriddle.com/tms1043-1.jpg www.seanriddle.com/tms1043-2.jpg

The back of the package had JAPAN - most of the TI chips don't have anything on the back.

The die was labeled 1040A and 1043A. I'll get some die pics up in the next few days.

I guess you could add the extra row of keys and get TI-2550 III.

Yeah, it's in MAME as the more superior TI-2550 III.

I fixed a problem with SM510 ATPL opcode. The programcounter is modified pre-increment. This fixes Gradius score display. The Game & Watch games also don't lock up anymore.

I posted the ROM dump from Cement Factory (ML102): http://www.seanriddle.com/gameandwatch.html

Unfortunately, the bottom right corner of the LCD is broken, and about 1/4 of the segments won't light up. I'll see if I can get pics of the LCD panel under the microscope and see how the broken pins are routed.

Ok, I verified the ROM and it's added to MAME. =)
