Hmm, I'm inclined to agree with George when he says we should stick to a programmming voltage of 10.5V. This may explain why your PROMs had such a stressful time, Slothie.

However, that's the same programming voltage as the good old Nat Semi DM74S571. If it's not the programming voltage which is different, what is?

Programming pulse length?
