Hello,
I also have a Dilog SU723A, but never managed to find any docs for it.
My board is revision D.
It works be very nice to find something.
As the MSCP / TMSCP selection is only a matter of firmware, I wouldn't be
surprised if the MSCP SU726A was the same board with different PROM.

Does the 723 work differently than the 726?
I'd saved the below 726 info from somewhere.
Info re Dilog SU726A
There is, indeed, a serial port. I have
found documentation for other
DiLog boards and on them the serial port
is relatively standard
(unlike the Viking, on which the serial
signals are embedded on the
SCSI connector I think).
The documentation also suggests there
may be two methods to get at
setup from the system console.
The first method (loading 77777 into
<SA> and then jumping to 2000)
hasn't worked so far. I am about to try
booting from 175000 to see if
that works. Otherwise, I will have to
look for the appropriate serial
cable.
The documentation I have for a different
DiLog board gives a Digital
part number BC20N-05 for the serial
cable, and also gives the pin-outs.
Here are the details:
Method 1: You need to know what address
the board is set for. The
board has two consecutive addresses in
the I/O page. In console ODT,
open up the first address and deposit 0.
Open up the second address
and deposit 77777. Start executing at
location 2000, thus:
@17760344/xxxxxx 0<LF>
@17760346/xxxxxx 77777<CR>
@2000g
Method 2: Install jumpers at JP13 and
JP14. Boot from address
175000, thus:
@175000g
In either case you get an "*" prompt.
Type FT to start the setup
program. (You can also specify a device
to boot from by entering a
device name and unit number here.)
Hope this helps the next guy.
