I believe this
was the chip used in late-model Commodore PETs (after
they designed out the earlier 6550 chips); maybe someone wants to
confirm this for the list.
Not sure. I think there was a redesign of the static PET, but I thought
it used 2114s (same geometry as the 6550s). There might be schematics
on funet.
I have a later model 2001-16N with the plastic case and I
believe it uses 8 - 4116's for it's 16k of RAM. I've got the eight
sockets and eight additional 4116's to upgrade it to 32k but have
never gotten around to doing it.
