I'll assume for now (until I take it a part and look at a schematic) that the empty socket I can see is where the missing ROM would go. Did R/S use different ECB ROMs in the Coco2's. I've located a couple and would like to be a little more educated on it prior to attempting this...
Depends on the CoCo 2.
If it has an empty 24 pin socket, it'll take a 68764-type eprom. One of
us here could probably sell you one. I think I have some extras.
If it has a 28 pin socket, that's a little more complicated. you have to
replace the 2764-type ROM with a 27128 eprom and solder a bunch of
jumpers on the board.
