Subject: EPROM programmer circuits

Since I got several very nice requests for details of my BBC EPROM
programmer, I have taken a little time to trace and diagram the actual
circuit I implemented, and document how it works. I have put a ZIP archive
with PDF documentation, a PostScript circuit diagram, the machine code
program to drive the programmer and the assembler source for the program on:

       ftp://ftp.dcs.ed.ac.uk/pub/ajcd/BBC/eprog.zip

and

       ftp://ftp.tardis.ed.ac.uk/home/ajcd/BBC/eprog.zip

Remember to use binary mode to transfer it! I'll be adding photographs of my
vero-board implementation to my web site soon.
