Unicorn Electronics has most of the TTL but alas

for a lot of the chips. Now might be time to order spares.

Agreed. BG Micro has some of the parts, too.

I agree about ordering spares. I'll try to remember to throw some on
my next orders for the future, since I have a number of PDP-8s to
maintain (I haven't checked, but I expect that most of the same ICs
from the -8/L ALU are also present in the KK8E).
