Works for me. The larger Eproms like 27128, 27256 and larger
I have loads of from old PCs that were junked. A ready supply
of fast and large (often CMOS) eproms make it easier to do that.
Though I had to mod my Prommer to do parts larger than 27256
the code upgrade was easy.

For that matter, why bother with UV erasers and
UV EPROMs at all?
Sorry to jump in, but I'd like to add my opinion. I have a few
reasons why someone might use UV EPROMs.
If you've got the right equipment, UV EPROMs are cheap, readily
available, highly standardized, predictable, and generally pretty
bulletproof.
