Homebuilt EPROM programmer?

[bizzybody]

Anyone got any links to plans for a homebuilt EPROM programmer? Especially if it'll work with various types of them.

If ypur interested in PICs go to the EPE web site http://www.epemeag.wimborne.co.uk/ and check out there ftp site there is a programmer that you can make and hook up to your computer.<p>B

I had some spare room on a PCB panel and did a few boards for this simple programmer: http://www.zws.com/products/epromr2/<p>I also wrote a very simple console Windows program to drive it. Unfortunately, it doesn't reliably do 256K parts although for the others it works like a champ. I think there is too much load on some signal on the 256K part as the address shifts over by 1.<p>Still pretty simple to build.
