I would be very cautious installing the 11/73 boards
into an 11/03
backplane.
You won't do any harm on a genuine DEC backplane; the worst that'll happen
is that BDAL18-21 won't be bussed. 11/73S machines were sold in BA11N
boxes, which are very similar to the original 11/03 and 11/23 boxes.
However, be wary of Plessey backplanes; some of these put 24V or AC
voltages onto the "spare" bus lines.
I have numerous BA23 chassis here if you need one but
I would
look locally for a MV2 or 3 to save shipping costs. I usually pick up
MV2's
for $5 to $50 depending on what is in them.
Also look for the BA123's. They were only sold for MV's but they make
good
PDP11 test beds.
MicroPDP-11/83s were sold in BA123 cabinets.
