I don't use one now, but I used to have a USB-powered programmer and it worked okay for GALs and 27Cxxxx UV EPROMs as well as EEPROMs. However, if I were using older parts, I'm not so sure. The interesting thing is that upon opening the thing up, you could see pads for a wall-wart barrel jack (unpopulated). So who knows, perhaps Bill's USB programmer is similarly equipped. I still use an older Xeltek Superpro for most things. It does the job. --Chuck
