Nice work Mark!

To anyone else ....

I have an eprom programmer that was developed by a local Toronto company
called Exceltronix. It came with a photocopy of the listings for the
Applesoft and Assembler burn routines.  It also came with a decent hand
drawn schematic. Total 16 pages. It uses personality modules (2716, 2732,
2732A and 2764) and it may be possible to figure out new modules for larger
eproms.

I had hoped to modify it to burn 27256 chips and have only gotten around to
downloading the data sheets for all the chips it can currently burn as well
as the 27128 and 27256.

It uses a 6821, dual 8212's, a 78540 and has a 28pin ZIF socket plus misc
bits.

Would there be any interest in my scanning this info in?
