That is why I am planning on using a small vertical PCB with the  PIC on it,
along with a few transistors & related components to drive the -15v outputs
(?) that it looks like the 4004 used. This verticle PCB would then be
point-to-point soldered into a 16 pin socket.

I'll see if Paul Pierce has the databook first, so that you don't have to go
digging :)
