I'd get a Data I/O 29B for the old stuff and a willem for the new stuff. Matches the era of programmer with the era of chips you want to program. There are software patches for the dos Data I/O PROMLINK program that allow it to run on a win XP computer and also a usb to serial converter for computers without a serial port. Others will chime in I'm sure.

I'm new to the list. I collect and repair/restore 8-bit microcomputers from the 1970's. I'm considering picking up one of the Willem EPROM programmers that seem to always be available on ebay for pretty cheap. I've gone through the list archives and see that there was a discussion on this subject several years ago but it didn't really come to any firm conclusion. My main use for this tool would be to program 2716s and 2732s. One of the tables in one of the ebay pages suggests that the device can test 6116 static RAMs which would also be useful. I have two concerns: 1) All of the ebay pages emphasize all of the new chips that these gizmos support. Has the "legacy" chip support been lost? 2) Whenever old programmers in good shape come up for auction, they go for a lot more than the "buy-it-now" on these Willems. Why?
