Mike Douglass solved it by putting an Eprom on the ZPB-A as there is a
spot for a 2708 1K part.
He made up a header to use more common signal voltage parts like
2716/2732 and so on.
With a machine language monitor that allows loading bytes to memory the
process is then easy.
Me I cheated and used a spare 64K memory board that used 2kx8 parts and
put an eprom (2716) in
the F000H space.? Change the CPU boot address jumpers from E800/E900 to
F000h and now
you can talk to it via serial port.
Thanks
That answered several questions that I was wondering about!
