I've got a FAST88 too, which "Norton's in" at a big 1.7 at 7.14 MHz.
How's this?  Your clone probably has two clocks, one for the processor,
one for the rest of the system, hence FORMAT & DISKCOPY run fine.
(It's also possible your clone isn't sensitive to clock speed the way
a PC is.) The FAST-88 on the other hand runs the whole system at the
higher clock speed.
