Hey Bill, good to see you here. Like most others, I have a Data I/O 29B for most of the older chips. I also have a Data I/O 19 which is capable of doing 1702As, but I only have half of the adapter and doubt I'll ever find the rest of it. I have an Szerlip S100 setup which will do the 1702As if necessary. For newer stuff, I use a GQ Willem model from MCUMall that is fully USB powered and has worked really well for me. If you don't already have a Data I/O unit, I have an offer for you - I have a couple portable units (I _think_ they're Model 60 but they're not immediately at hand so that may be the wrong number) that have failed with RAM errors. Whatever the number, they are essentially 29Bs with multichip adapters. Nice and light, and built into a clamshell case. If you really feel like fixing something, I'll send them both to you for the cost of postage - fix them both, send one back to me and keep the other - best, Jack

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?
