Hrm, does he still have that set up? Maybe it can be used to dump tms7041's as well.

I wonder what the 1 in 7041 means though; an additional feature, a special instruction, or protection of the internal rom?

I've added the tms7041 cpu to the exl100 and exeltel drivers plus placeholders for the undumped tms7041 roms.
