My IBM PC/AT's F/H disk controller bit the dust; is it possible
to replace it with something better (and usable both under
Xenix and DOS), e.g.
1) A controller that supports 1.44Mb, preferably as A:
(to do so it would have to have on-board POST rom to
replace the AT's default boot sequence, wouldn't it?); *OR*
2) A controller with on-board cache, possibly enabling 1:1
interleave; *OR*
3) A RLL controller that packs more onto my Bell B/86 drive
(actually a Toshiba 86Mb unformatted, ~70 Mb drive), originally
running with IBM's MFM controller.
Is it possible to use a RLL controller with a disk intended for MFM??
I don't know whether that's a feature of the controller only, or of
both controller and disk. Thanks---- Please reply by e-mail to
