Didn't Topcon stay at the stopdown metering table a little too long?

It got more complicated than I had hoped. The donor camera was a later
model with max ISO of 800 and an f/1.8 lens. The recipient camera was
limited to ISO 400 and had an f/2.8 lens. I can't remember now for sure but
I think I had determined that I was going to need to add a fixed resistor to
the circuit to compensate for the differences. That's when I stopped
working on it and haven't finished it. But I had good intentions. :-)
