Old Crow P4700J Restoration
bussboard was my answer to the ailing buss bar setup. I got tired of soldering/unsoldering
the power cables for modules, and put in screw terminals on a circuit board
that has nice, big power traces and lots of power-supply filter caps to
keep the voltages stable. There is one bussboard under each module row,
and a big molex connector to the power supply.
is the good old 8782+8700 keyboard, but where are the telltale blue circuit
boards? Well, they were getting kind of peaked (moisture corrision; the
head unit was better-sealed (and all boards have long since been Krylon'ed
to keep them in good shape) and I decided to replace them. To that end
I replaced the power supply--the old one of which ran hot as it was--and
designed my own.
