Tony Duell's maxed out 5160 and PDP

...

  My pre-PC systems (mostly Z80 CP/M)
 all support 4 floppies per the original specs.
 But NOOOOOOOOOOOOOO, the PC's "cable twist" ruined that,
 limiting things to 2 floppies and 2 hard drives per controller.  
 Who ever used more than 2 floppies on a PC anyway? Or more than 2 hard
 disks (back then, before PC based servers)? 
Well, I did, obviously...

The reason is that there are totally incompatible disks (you can't put a 
3.5" disk in a 5.25" drive or vice versa and get it to work [1]), and 
having 2 drives of each type is handy for making backups (you do make 
backups, right...)

[1] I put that in because otherwise some smarta**e is going to say that 
if you fold up a 5.25" disk it'll go in the slot of a 3.5" drive.
