I didn't see K1/2/4/8/3 in your 0980 hw descriptions, so, FYI here they are for ti30 and tiprog (probably others too).
// pin 10 k1
// pin 9 k2
// pin 8 k4
// pin 7 k8
// pin 6 k3

TI0980 emulation is pretty much working here. The algorithm to convert the raw dumps to 0980 is still valid, except for this line:
int mypage=page; // TODO/verify
change it to this:
int mypage=(page<8)?(page^7):page;

And by the way, do you have a die pic for that TMS1100 Star Wars game? The dump should be correct, but we don't have the PLAs.
