If you need to program a 28C16 parallel EEPROM it

pretty simple to build a circuit to do that, at least for something
like the Atmel 28C16 part which only needs a single 5V supply unless
you want to Chip Clear.
That is what is frustrating at the moment, the few designs I have seen
on the web is about 3 chips and a zip socket.But alias the only low cost
one I have seen is from the UK, and the VAT and shipping will kill me.
I may breadboard up one, but I am not sure if I will use 28C16's or
2732A's yet.

PS.
That programmer must have cost a fortune to have 4004 in it.
I had a EPROM programmer once in a Z80/S100 bus cpu kit about 1982
( 2 slots?) but the it was lost in moving years ago. Also it I think was
toasted with a homebrew power supply failure. I have seen alot
of 8080 systems talked about very little on kit computers on the net.
