If it is enough to grab that one line (after Gerrit's e-mail I got enlightened ;-) than I'd leave the original ROM where it is (especially if not socketed) and tap only on the line either by cutting a trace or unsocketing a pin from PLA. I believe it is better to let also people with soldered-in ROMs do it without unnecessary desoldering. Of course if someone has it socketed and wants to save some milliamps - sure. But I would prefer not to _require_ removing the chip. -- SD! Message was sent through the cbm-hackers mailing listReceived on 2012-06-05 23:00:20
