I had qualms about making that statement -- since I'd run into variants before. I should have said that
I had a 2340 that had 7.5 and 15ips.
I knew I had a picture of a 2340 around here and I thought it would be fun to see what the markings on the speed knob on this particular unit said:
In case it's hard to read, the speeds are:
H and
L
... so I'm guessing that they were,
at the very least, keeping multiple speed set options open.
Oh, and I should also say that I've got
VCO (voltage controlled oscillator) and
VSO (variable speed operation) bouncing back and forth in my head and for a moment I almost started to doubt my notion that a VCO of some kind lies at the heart of of any circuit or module designed to implement VSO for hysteresis synchronous motors.
