I'm proud to say that I have a much older 6567, a 6567R5 from 4382 or so.
Yesterday I accidentally tested it on my VIC-20 (I was going to send a
6560R2-101 to someone), and luckily it survived the treatment.

I didn't know that the 6567R8 was packaged in ceramic as well, but it is
not so surprising, since the 6569R3 (which seems to be the equivalent 6569
revision) was manufactured in both ceramic and plastic.
