This is an old thread. I finally got around to taking
a look at both
my DILOG TMSCP SQ3703A REV G and MSCP SQ3706A REV H controllers side
by side. All of the DIP parts in sockets with labels have the same
numbers on them, except for the EPROM.
As a quick test I replaced the EPROM from the TMSCP
the EPROM from the MSCP controller and now it does appear to be
functioning as a TMSCP controller.
I did have to change the CSR
address from the default TMSCP address to the default MSCP address in
the controller configuration menu...
but didn't do anything else and was then able to
boot from a SCSI DISK device.
Very good to hear.
I'll have to dump the EPROM contents (27512) in
case anyone else has a
SQ3703A TMSCP controller they would like to try as an MSCP controller.
I would love a pointer to this when you do it. I still don't own any
S-box hardware but I'd be willing to drill out the rivets and replace
the handle with one that will fit in my BA23 or BA123 (or if I could
find one of those 4-slot S-Boxes that was a DEC comms controller, I do
have one of the S-box CPUs for it that is really a PDP-11/53 board
with different ROMs - that plus an SQ3706 would be a good start to a
