Perhaps all is not lost.  I'd have to go and look at my 1542CF, but I
believe that I discovered that it uses either the Intel 82077 or the
National PC8477 chip.

That being the case, if you're handy, you can simply replace the Intel
chip with the National one.  They're pretty much pin-compatible (the NSC
one requires a couple fewer external components).

There are many other SCSI controllers that have decent FDCs.  I've had
good luck with Ultrastor and Future Domain cards, for example.
