I feel kind of dumb here. Went to order a GAL22V10 from Jameco and instead ended up with a Cypress PALCE22V10 (see here).
As far as I can tell from the datasheet this should be a drop in replacement for the GAL22V10.
However, it doesn't appear in the list of chips in the software for my programmer (TL86II+). I tried using various similar chip settings and although the programmer apparently can read the chip, it errors out with an overvoltage warning when trying to write.
So my question is...Does anyone know of a way to program a PALCE22V10 with a TL86II+?
