I've never really felt a need nor desire to run a multitasking OS while
analyzing diskettes. The best way to multitask is multiple machines.
YEs, but the only useable OSes for PCs happen to be multitasking...
And I have little enough space here that I really don't want to have to
set up another machine just to image disks. If I did that, it certainly
wouldn't be a PC, and wouldn't have a 765 as the disk controller.
I grew up with the WD controllers, and found the
8272/765 a real
disapointment after those :-)
WD is certainly a better match for what WE like to
do. But the 765 works
reasonably reliably, and is prob'ly just fine for what SOME people want to
do.
The WD controllers are no worse for doing what most people want than the
765. It's therefore a pity IBM picked the 'wrong one' for the first PC.
Actually, I think I have a PC-not-quite-comptible here with a 2793 in it (!).
