Hi James,

Have a peek at the ZX97lite which is a stripped down version.

http://www.xs4all.nl/~rodneyk/zx97_e.html

I worked with Rodney Knaap to adapt the ZX97 to fit on a single sided PCB.
Additional memory and I/O are connected via a flex cable on the expansion bus.
I also have several designs, including a 6 chip version, of the EZ80
controller (no video, blank slate OS, 24 I/O, 32K nonvolatile memory) which is
programmed via a PC printer port. When loaded with modified ZX81 rom code,
control programs written in ZX Basic will execute on power up.

regards

wilf
