For yucks, I asked for a quote on some schematics from "3prime-solutions.com"
that were listed on their web site (11/84 and HSC50 schems..)
MP-01426-00......USD$2805
MP-01955-01......USD$1356
MP-02011-01......USD$1617
I was once quoted over \pounds 1000 for the printset (schematic) for the
861 power controller (relay box, essentially). I can assure you I
laughed for a lot longer than it would have taken me to draw it out from
the device!
