Cmon Paul, we know you enjoy it when Don tortures you....
At least some are in sockets....

God does not have mercy on you, but I am happy to absolve
you should you choose to drive your car over the MARFs...
I won't miss 'em....in fact, other Buchla 200 owners will
probably give you a standing ovation....because theirs will
then be worth more!

> I spotted 2 VERY NASTY ICs form this era: SSS was the worse CMOS vendor in history.

Legend has it they went bankrupt due to the many lawsuits from OEMs.
I too saw their chips go bad at amazing rates.

That's nothing, you should see what happens to the "striper" film caps that
McIntosh used in their tube hi-fi in the early 60s.
