Today I powered up the "new" 11/03-L, with which I have absolutely
no experience. The POWER OK light blinked slowly on and off for a
while and then went out. Now it doesn't come on at all. The top
card in the cage, though, has a row of red LED's and a large green
one, all of which are lit.
Power supply is H7861, cage is BA-11SA.
The cards from top to bottom are:
M8189
11/23b
2 Mb Clearpoint memory card (don't see a model
number)
M8061
RLV12 cartridge disk controller.
M7957
DZV11 serial mux.
M8053
With an M8064 it would be sync controller DMV11
Dilog CQ 1610 card (what is it? Many 2861 PLCC chips in
sockets)
2861 is a serial chip, likely a multiport serial card.
M8029
RXV21 8" floppy interface (RX02)
On thing is for sure it's not an 11/03! the 11/03 CPu is either M7264
or M7270. You have an 11/23B (M8189).
I didn't see a lot of 11/03 manuals on the bitsavers site. Before
I do a lot of searching and headscratching, can one of the -11
gurus tell me what kind of beast I've got here? Or point me to the
appropriate manuals?
For certain you are looking for the wrong thing anyway. If you'd found
11/03 manuals it would not cover much of the hardware listed. The base
system is 11/23B (or 11/23+) and you need to find individual manuals for
the boards as that is likely a hybridized system and not a stock
configuration. By that I mean either someone dumped all the bards they
had in it or it was built as a special purpose system.
