[net.micro.pc] PC/AT PROMS and crystal

lotto@talcott.UUCP (Jerry Lotto) (10/16/85)

	Recent rumor mill (PCWeek) stated that the new PROMS being
used in PC/ATs (with the IBM 30mB disk as well new 68 and 99 models)
will make replacement of the crystal difficult or impossible. They go
to state that the PROMS change a timing loop, but offer no other
substantiation of this claim. I believe that the PROM has been modified,
but what evidence is there that this causes the previously mentioned
problems?

	If this is true, I for one would interpret it as a hostile action
by IBM. There is no way that they can convince me that limiting the
capabilities of my machine is for my own good. I am grateful for the
open architechture at least. It would not be the first time I was forced
to kludge around one of their "fixes".
