I have made several ROM replacement sockets for the masked programmed
Motorola 6800 MIKBUG ROM used in the SWTPC 6800 system. The MCM6830 ROM does
not have a EPROM equivalent. The replacement board has a 74LS20 (to map the
4 enables) and a 2716 EPROM.
The challenge was to find pins that could be soldered into the ROM board
that would plug into the existing socket on the CPU board. I bought several
types of pins and headers from surplus stores and Digi-Key. I have
determined that capacitor leads are the best solution. Many capacitor lead
are made of steel and are much stiffer than resistor leads. The ones I get
from 0.1 uf bypass caps are just the right size for
machine tooled sockets.
I can make a lower profile adapter then if I use header
pins.
I describe the process (with pictures) in the Users Guide on this page.
