Thank you for your kind reply.
OK from the beginning.
1. The 11/94 is housed in deep box located in a 42inch cabinet. It
uses a KDJ11-E Quad proc. board.
2. Two buses (Q and Uni) are housed in the one box and are linked by
a special interface card.
3. Via a pair of flat cables the CPU is linked to an I/O panel at
the rear of the cabinet.
As well as six nine way D (rs232) and one 25 way D (rs232)
sockets there is a set of dip switches to
set up the console serial line parameters. There is also a two
digit power on self test progress display.
4. On switch on the self test progress display and the LED's on the
edge of the CPU card count down
from 77 to 04 (normal run mode)
5. Dialog mode is entered as set by the dip switches on the I/O
panel. Sometimes it gives the List Boot etc.
Hitting any of the choices just drops you into set up mode.
Setup does work and you can save the changes.
6. The main problems are that if you try to get it to boot it says no
controller to every device except DD
and that says no drive. Secondly I cant get it to go into ODT to
look at the registers.
1. The PROM appears to be genuine DEC. KDJ11-E Monitor V 1.06
2. I have seen it the mode where it offers List etc but only with VT100
