I will probably have some empty BA213 QBUS housings available free for
shipping. I will know if I want to grab these if I find anyone interested
in them and if I can find a box big enough to hold them as I have little
use for them myself.
I'm interested. I have no Qbus boxes newer than BA23/BA123.
Either of these units might help give your QBUS
Microvax some Q22
breathing room.
Yay!
On a related note, I recall that there was some
ability to convert the
KDJ11 module for this DECserver into a working PDP 11/xx (83+?) with a
PROM swap? Does anyone know more about this and its feasibility?
I traded some BA23 handles to Jon Engdahl for a DECserver CPU board
with BA213 handles. I haven't pulled its handle yet. He did the work
of putting "normal" KDJ11 boot ROMs in it (and moving a jumper or to,
ISTR). It's an 11/53, effectively, based on speed and local RAM (there's
a couple of flavors of it). I don't know much about the board other
than the obvious CPU flavor and RAM, etc. I am not a guru when it comes
to stuff that new. I'm fine with Qbus, but I really know the KDF11 stuff
best.
My goal is a 2.11BSD system, especially since I have more than one
KDA50 (and a couple of RA70s). KA630s just aren't special enough
for me to spend lots of time on; I'd rather fire up the 8200.
