Ben, if you need a low cost EPROM programmer just go get yourself a junk PC
(practically free) and for $20 on Ebay Buy-It-Now (or less if you are
patient), get a Willem Programmer.
Here is a link:

Decent EPROM programmers are so cheap now as to be hardly an issue.
These are super simple to use and practically disposable. They are
amazingly durable and useful.
They won't work with first generation EPROMs but anything 2716 or later is
good. 2816s should be no problem.
Good luck with your project.
