Thanks to comments from Tony, Julian and Henk, I think I now understand
how this thing works.
I'm not _quite_ ready to power up the CPU so I haven't confirmed the AUX
ON/OFF front panel switches functionality, but based on the responses,
it seems clear what I should expect.
I have, however, confirmed the functionality of the Local On and Remote
On settings on the 874 itself, and can confirm that the 3-conductor link
between the two 874's is doing it's job properly.
In response to Julian's interest, here's the configuration of this
- KDF11-BA processor
-- 512MB (MSV11-PL)
-- x2 4-line serial muxes (DZV11)
-- a single line (DLV11)
-- Controllers for the drives (RLV12 & RXV21)
- x3 RL02 w/ a handfull of diskpacks
- RX02 dual-drive
- x2 VT100
- x2 VT102
As I mentioned in the original post, this is all housed in a dual-wide
40" roll-away cabinet (frankly, I have no idea what it's model
designation is) with two side-panels/uprights and a connecting 'panel'
And, I've got an ASR33 on hand that I might hook up later, for grins.
I've got RT11 on the disks right now, and though my eventual goal is to
get RSTS running (thanks, Julian, for the offered assistance!), I'm
actually going to spend some time with the RT11 first, getting familiar
with that, also for grins.
Again, thanks to all for the heads up on how this power gear works.
