EEPROM adapter for Tandy Model 102 system rom
With REX main rom support.
Use this version also for late-model 100's that don't have the non-standard main rom pinout. (If you have a Model 100, and the main rm is NOT a LH535618, then use this instead of FlexROM_100)
Use this version also for NEC PC-8201/PC8201A
PCB: OSHPark
BOM: DigiKey
KiCAD schematic and pcb sources: github
Directions all the same as FlexROM_100, except in addition you have to desolder the system rom from the mainboard and install a DIP28-0.6" socket in it's place.
