Are you going to mention how we had the polaroid's of the Signetics part
up in the chiplab?  Or the bad job we did of passivation?  The PLA's were
in some way not very boring as they were our last salvation to pull a
problem out of the fire, and our chance to impart any coolness in logic.

Hi all,

I'm writing a short article about the C64 PLA and want to do some more
investigations. No, I do not expect to find something thrilling in one of
the most boring parts of the C64 :)

So if you have broken PLA chips it would be nice if you could contact me.
No matter of which type, from original bipolar PLAs to the MOS version.

Thanks!

Thomas
