I don't recall ever running a Tarbell single or double density
controller in a system with a 4mhz cpu.
Exception to that was running it in a Tarbell CPU equipped system
I always had an Imsai backplane for what that is worth.
I also had a Northstar system which I merged the BIOS with the Tarbell
controller, so I could dub 8" to 5 1/4" HS floppies, and never had much
problem with that.
All of my Tarbell hardware was tuned up by Dick Culberson or Don for
what that is worth.
Both have passed away, and are not around to help with this discussion.
