Program your next EROM in BASIC. Schematic for a 2708 erasable read only 
memory reader and programmer which uses parallel IO ports to set data and 
address. The software to drive the programmer is written in BASIC.

Apoloiges I should have written 'as well as sending money I can also provide 
copies / scans etc.'

Thanks, I've borrowed one of these in the past, and it worked fine with 
single voltage EPROMs (like 2764s) but most 2708s require 3 rails including 
-5V and -12V. Also the Willem has a limited programming voltage (unless you 
add an external PSU).

OK, thanks for that. I've just found on comp.os.cpm that Steve's articles 
are also in his book 'Build your own Z80 computer'. I don't think these 
books will be in our local library, they tend to clear old old books to make 
way for new ones. I would welcome offers from anyone with the book versions 
also.

John
