http://bitsavers.org/pdf/dec/disc/rk05 Oh, nice. Only missing the
actual exerciser.... ;-)
Just build one from the schematics ;o)
I looked over the schematics, and I can't figure out how the signals
on the cable from the RK05
to the exerciser line up with the signals from the real RK05.
I made a little table of the signals in A & B side and I can't get
them to line up with those
on the exerciser. I must be missing something. All the other
functions of the exerciser
make sense, as does the internal writing. It's just the "bus" wiring
which seems missing.
The schematics show a 4 slow backplane with 2 sides for each slot. It
shows a few connections
between them, but nothing about all of the signals from the cable.
I'd be happy to share my
text file with anyone who wants it.
If one were going to re-create one of those exercisers, it seems like
some information is
missing. Maybe someone has one? I suspect there is a lot of wire
wrap from slot 1 to
the other slots, but I can't see anything in the schematics to
indicate what pins.
I thought at a minimum it might be fun to do some schematic capture :-)
