This may be the set I found. It has a checker and a speed verifier. I
guess I should pull them out and see just what kinds of chips they work
with. I didn't expect them to work with 1M chips, based on how old they
looked, but if thats the case, they may not be usable for the 64k chips I
was hoping to use them with.
