How about the 3 inch Mitsumi "Quick Disk"?
No sectors or one
sector, depending on how you look at it. Not a Shugart interface,
but used on early Nintendo boxes, Korg synths, Smith Corona word
processors...
If you can find me a pinout for the drive, I'll tell you...
As long as data is transmitted in the same form as a Shugart-interface
drive -- a pulse every time there's a flux transition -- then there
should be no major issues. Obviously adapters will need to be made up,
but that's not usually a big deal.
Worst case would be wanting to connect an Apple 400k Mac drive up to the
analyser -- you'd need to generate the PWM speed control signals
manually. Adding support for the status readback channel and 4-phase
stepping would be a bit of a pain as well... I'm calling that one
"theoretically possible, but there are better solutions"
