Hi All, I've been testing an M7869 recently and noticed that my 11/34 would give a BUS ERR whenever it was halted or if I tried to read from the switch register, so I used the "wholly scientific" fingerpoken troubleshooting method and noticed the ROM at U33 (P/N 23345A9) was piping hot. Does anyone have a dump of this ROM that I could use? Regards, -Tom
