C64 EPROMMER
------------

Here's the circuit for an EPROM programmer that I used to use with my
C=64. Although I never had a circuit diagram for it I managed to trace
the PCB and reproduce another working version. The circuits have been
scanned into two GIF files... I hope you can make sense of my scribble!

There is also a disk image of the control software availble in the image
file EPROMMER.D64. If you have a copy of "star Commander" then you can
quickly reconstruct a floppy!

The following EPROMS can be read or blown:
2732   2764   27128   27256.
Programming voltage is selected manually by a switch, as is the type and
pinout (24 or 28pin). You will need to refer to manufacturer's data sheets
for the appropriate EPROMS.


This is not by any means a "finished project". I am merely making the
details available in the hope that someone with the time and enthusiasm can
make use of them and develop the project further.
