Thanks, you have given me hope. While the model # stickers have worn
off, there is a serial number that seems to be like 703AQ1570, and the
board has a revision K.
I'll report back when I have gone through all the gyrations to test it
on the LSI-11
cheers,
Nigel

A few months ago, thanks to help from several
people here, I converted
an SQ703 TMSCP controller to SQ706 MSCP.

It seems that one of the PALs is maybe setting up the address!
Anybody else tried this?
I never tried it with a Dilog SQ703 and SQ706. The two
that I have
have numerous differences between the boards, which made me skeptical
that just a simple EPROM swap would be the only change necessary.
However with the newer S-handle versions of the Dilog TMSCP SQ3703A
and MSCP SQ3706A boards that I have, they appear identical except for
the EPROMs. On those I did try swapping the EPROMs between the two
boards and that did appear to completely swap them between TMSCP and
MSCP functionality.
