I got TI Math Marvel: TMC1986A-NL DAS 8136 PHILIPPINES
I got another Tiger Copy Cat to try to electronically dump the TMS1730's ROM. I can shift bits into the program counter and see them come out O7, but I haven't gotten it to dump the ROM yet. I'm shifting bits in on pin 19, but I expected K1 to be pin 18. So I'm not sure if the K inputs are not in order on the pinout, or if they changed the input line for ROM dumping from K1 to K2. On the TMS1000/TMS1100, you have to drive R10 to get output on O7; since there is no R10 on the TMS1730, I figured they used a different R line, but O7 outputs with no R line driven.
