This is very interesting. The Winder 1 I based the modification
instruction on is a late 1979 vintage, with a serial number in
the 179 thousands. I do not remember how close that is to the time
of change from Winder 1 to Winder 2.
I have just checked the circuit in my Winder 2 (age unknown, serial
number in the 373 thousands) and that is an entirely different
design.
Obviously Olympus has been tinkering with the design, probably
to improve the reliability and/or lower the cost. Now I wonder
how may Winder 1 variants there are out there?
Anyway, it is clearly time for me to update my web site.

Lars
