Much the same,
but with a TS05 (Cipher F880) 9-track mag-tape drive in
place of the RL02, and a TSU05 controller in one of the Unibus slots.
Ah... I'd forgotten about that configuration, but I don't think it was
very common. A TU80 alongside was somewhat common.
That's the configuration my machine came in (A friend and I bought a pair
of them). TS05 in the top, TSU05 card in the CPU box.
It was a standard DEC configuration, it was mentioned explicitly in one
of the manuals.
There are 2 serial ports (Console and Remote
Diagnostics) built into the
CPU. You can add things like the DZ11 if you want more.
There's room in the I/O bulkheads for a DMF-32 (8 async, 1 sync, 1
printer), and IIRC, it was somewhat common.
My 11/730 came with a BA11 10.5" expansion box (BA11-K IIRC). It
contained a DMF32, and something else which I forget. There was a little
card in the Unibus Out slot of the CPU backplane that linked to the
bulkhead with 3 ribbon cables, That took a flat screened cable with 3
connectors on each end that went to a similar bulkhead on the expansion
rack, then 3 more ribbon cables to the Unibus In slot of the first
backplane in the BA11. Again a standard DEC configuration according to
the manuals I have.
