Wow. Quite a history. Mine were from Borden in downtown Columbus. The
guy that helped me get them, used to use them in the late 1970s. His company
(and my one-time employer) was the place I've mentioned several times that
made DEC<->IBM sync serial connectivity products. For anyone that ever would
have worked with them, they were known as COLA and COLE (COLumbus CPU "A" and
COLumbus CPU "E"), part of a once larger setup. They are identically
configured with the remote-diag console, 4Kw of MOS in one BA-11 in an
attached memory cabinet (H-960), SI9900, several Fuji Eagles and a couple of
TU-77-sized tape drives. *Those* were a bitch to move. Fortunately for me,
it was all in town - $100 in moving expenses. Maybe I'll be able to get one
back together and powered up by Spring. I'm still fiddling with my set of
PDP-8/Ls that all appear to have dirty backplanes.
