Well just because you don't have enough to do please plan on an ISA version as well ;) I think it really is time someone did a super floppy controller bringing together a number of older technology on to one easy to use card (e.g. 8" drive support, copy protection bypass, GCR reading) - all of this was available as separate products in the past... > My friends think it's silly, and they're probably right. =P Hey silly things can lead to great discoveries: https://gizmodo.com/scientists-produce-rigorous-study-of-why-grapes-spark-i-1832660386 -Ali > > On Tue, Feb 19, 2019, 1:18 PM Ali <cct...@ibm51xx.net wrote: > > > > > > > Now that I have my glorious disk toaster (2D model I think, says > "2D" > > > on > > > the drive levers), I want to build a controller for it.
