Hey, if I can do it, anyone can. I started with

don't know the right way to handle BGA packages doing manual assembly,
so I steer clear of those.
FWIW, I've got a motherboard here (386 or 486--I don't remember) where a
QFP CPU is mounted on a carrier that plugs into a PGA socket. The thing
was purchased in that configuration.
Back in the 80's, what cpu's were for S100 boards other than Z80's
,8080's
and 8085's?
I've sold a few M68k boards from CompuPro and retain one for my own use.
Such a board was used to make an M68k S100 machine running a port of Sys V
UNIX called TRICEP. I sold Al Kossow such a machine about a year ago.
Al, what's the status of that machine?
I've also found boards with 8088, 8086, 80186, 80286, and something from
National Semiconductor that I forget. I have an advertising flyer for an
80386 CPU board somewhere.
