Devices of interest are Atmel 28C64 or equivalent, and Lattice 22V10 in PLCC28 packages (I am aware I will need an adaptor and have sourced one already). The cheaper/nastier the better! My budget is non-existent in the bad way, so I'm hoping there's a Chinese one that's "good enough". Failing that, at least let me know if there are any to avoid.
I might be able to get a Dataman S4 from work on extended loan, but I'm not sure if it knows how to program GALs, and nobody else seems to know either as it hasn't been used in a very long time.
