Kevin,

sounds like you're thinking of the 11/83: the TSV05 would be Qbus, as
are 22-bit buses. The 11/84 should be UNIBUS, if I am not mistaken. So
it should be TSU05 then (same drive, different controller). I/D space
and large memory is still right, of course. Nice machine for sure! I
wish I could afford having one sent to Germany!
