Strangely enough, trying out ADTPro with it on both Windows and OSX,
this little IIc was able to transfer disks back and forth flawlessly

timing inaccuracies over time? Or was the problem only with more
hardware-ish devices like modems and printers?

I found exactly the same thing with my original IIc.

I think the devices most affected were 1200bps modems.

I have double checked the numbers and provided the device at the other
end of the link is not clocked faster than the standard, the IIc clock
being 3% slow is within the tolerance of the Async serial format to
adapt to.
