A timely question as several of us seem to be working on this model
currently. [Thanks to Julian, Tim, Don, Al, Henk, and all others
that have contributed to my own success...] Others will no doubt
correct my errors but...
I believe for the configuration above one H744 (position 2) IS
required. I believe a H745 (position 1) IS also required. A second
H744 (position 3) does NOT appear to be required based on your
configuration above. I'm not clear whether or not a H754 is required
in position 4. My take is that regulator is used primarily for core
memory (+20, -5), though I could be wrong.
Note that there are other regulators that can be used in place of the H744.
