There are some PDP-11/23 (PLUS) BA-11 boxes on Ebay, but the prices are high 
(IMHO), some are beat up and I don't think the straight 11/23 BA11 can support 
a MV. I'm pretty sure they are 18-bit.  The 11/23 PLUS are 22-bit and might 
work, but I think are Q22/Q22 rather than Q22/CD slots.

I just got a BA123 about 4 months ago after a 2-yr search.

The issue you'll have is that BA23 chassis are just too convenient for those 
with PDP11 boards, and BA123 chassis are large and hard to ship (and rarer than 
their BA23 counterparts)

Good luck,

I am building up a micro vax and need an empty chassis.

Given the number of dec boards on ebay, I assume (hopefully) that there are 
some empty chassis
out there.

Please PM if you know of an option.

tnx
