[Coco] Disk Controllers

[Robert Gault]

Adapting a 28-pin EPROM to a 24-pin Disk ROM socket is simple but a tight fit in 
some cases. I've done it with a low profile socket stuck into the controller 
socket with the EPROM plugged into the top of the stack.

Take a low profile socket and bend out pin 20. Solder this pin (with a wire) to 
pin 22. Solder together pins 26, 27, & 28 connecting these pins to pin 1 (with a 
wire). Solder a wire to pin 2 and plug the other end of the wire into pin 20 of 
the controller socket.
Now plug the adapter into the controller socket so that pins 1,2,27, & 28 don't 
go into the controller socket but pins 3-26 do insert. Now you can plug your 
EPROM into the adapter.

Good for a 27C128 EPROM.
