[Coco] Adapting a V9958 64-pin Chip to fit a Solderless Breadboard

Mon Dec 2 23:32:38 EST 2013

Hi, Kip -

I have 10 - 15 of those 64 pin sockets that I picked up for a Z180 
project that never went anywhere. They were hard to find, and as I 
recall, a couple bucks apiece. The sockets are solder tail with no 
manufacturer's name or mark (that I could find).
