would not be possible that an USB-powered prom programmer would work, but
I'd personally want to stick with something with some legroom. I always
measure my USB supplies and cables' output to separate out the ones that
don't provide enough umph from those that do.
Happy computing
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.
