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
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:
Method 2: Install jumpers at JP13 and
JP14. Boot from address
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.
