There is no complete PCB or
schematic available. If you intend to build the project , you will
have to design it yourself. Still, all the data for the EPROM programmer
is available here, and combining it with a Z80 system should not be
difficult. Actually, it is better to have 2 or 3 separate PCBs (Z80
system,EPROM programmer, glue logic) and leave the EPROM programmer
as it is.
a schematic similar to the one we used for our project
(156 Kb) back ups of the PCB we designed. We used TraxMaker
2 from for PCB design. The finished PCBs(7&8) are erroneous.
If you intend to use these PCBs start from 2.pcb. The PCB is 2 layers
but all the tracks on the top layer are straight and can be replaced
with wire bridges to lower the cost.

Supports Intel HEX and Motorola S1 files but it cannot be used to
program RAM (programming algorithm seems to be different).

but it is possible to make it a single layer pcb by omitting the top
layer, changing it here and there a bit and adding a few more wire
