That's good to hear. I wasn't going to have any cycles to look at this

Seagate half height 5" is well past its use
by date. These are really
needed for 8" Quantum 20x0 replacements. Q2080's were marginal 15
years ago. I don't think I have any that are left working in my Xerox
8010s.
I'm prototyping an MFM drive eliminator as we speak. It takes quite
a bit more horsepower than a floppy simulator--but modern
microcontrollers are up to the task. The current design is for 5MHz
data clocks (standard MFM); maybe RLL (7.5MHz) later.
