I'm looking to program the old Intel 1702A EPROMS, very popular in the early 1970's. I've looked at the posts of various home-brew programming options, none seem easy to obtain or easy to use, or are more expensive than I want to invest. Then I realized I've got several old vintage EPROM programmers in my junk piles.
I pulled out an old 1975 Intel UPP (Universal PROM Programmer) in real poor shape, but my research is that without an Intel Intellec computer (which I don't have) these would be a bear to interface and use. Then I opened it, and I have "zero" of the personality cards, just the main 4040 board, so that won't work.
Then I pulled out this WALMOR Data Systems, Inc UPC 2600 programmer, about 1985 vintage, and I figured it might do the 1702A's. But I searched for hours, could find no manual or specifications online. I can find a few advertisements in old magazines of it's predecessor (I think the 1100 maybe) but none of the advertisements listed EPROMs programmed. I had nothing to lose, so plugged it in, and tried to enter device numbers, 2716, 2732, but after about 45 seconds it started to freeze up, likely bad electrolytics, and it'll be a project to get it working right.
Before I try to replace the electrolytic capacitors, has anyone ever heard of these WALMAR UPC 2600's (or the prior model 1100) and know if these can program the Intel 1702A?
I do also have a vintage Pro-Log (I think it's the Pro-Log M980) which uses the Intel 4004, but I haven't plugged that in for 20 years, and wouldn't do that without replacing all capacitors, and separately testing the power supply outputs.) I have been thinking maybe I should refurbish that, and I'm certain that does program the 1702A.
So, in short, anyone know anything about the WALMOR programmers?
