[ale] EPROM programmer?

Here's a simple one that uses an Arduino Mega. Microcenter in Gwinnett has
them on sale for $11. It looks like the sketch does the heavy lifting and
timing and uses a serial interface protocol to deliver instructions. The
page has a python script that will drive it. So a Mega, breadboard,
jumpers, and the software on the page should be enough to get you going:


Note that Microcenter now closes at 7PM.

Hope this helps,
