[Coco] Attempting to upgrade a CoCo2

[Arthur Flexser]

Nope, you'd need a 68766 EPROM for a 24-pin socket, hard to find
nowadays.  You might need to get an adapter socket to accommodate a
28-pin 27128 (assuming you are putting both Color Basic and Extended
Basic into a single 16K EPROM, as some CoCo 2 models require;  a 2764
would do for Extended Basic by itself.)
