Would you also like the schematics I traced out of the Boschert OL130
SMPSU and a little Boschet 12V linear regulator? They are part of the
Atlantic Research Intervew 3600 that I worked on last year.

I also have the official ICL document for the PERQ 1 power supply
section, which is a Boschert unit. It includes the schematic (most of
it, the -ve resistance board is not included for some reason). I can
try to scan it if there is any interest

Note that many of these units contain 'selected' transistors. That's
one reason for the house numbers. It may well be a 2Nxxxx but one that
has been tested for some parameter. Without knowing what it was tested
for you are going to have 'fun'.
