My Cipher F8 series 9-track died and preliminary analysis seems to point to an EPROM on its way out. (CPU crashes on first interrupt from a CTC that appears to be serving as a clock tick generator. Hard to tell without schematics...) Since I didn't think to make a backup while they were working, would anyone care to send me a dump of working EPROMs? Dan Lanciani ddl@harvard.*
