I took the plunge, and ordered an EPROM UV eraser (little box with a UV lamp
and timer) and a cheap EPROM/EEPROM programmer off of eBay tonight. I'm trying
to source some cheap AM27C020 EPROM chips for the SS2 so I can have backups in
case I screw up. The original EPROM with the 2.4 version of the firmware isn't
much use to me, but it IS better than having a totally dead machine.
2.9, here we come! :-)
