[Coco] ATX PSUs

[Frank Swygert]

Yep, the Super IDE board. That SuperBoard will really be neat when it comes through also. Not trying to needle you about it, I know it takes a lot of work and time. When you finish with that you can start on some kind of accelerator... someone's working on a FPGA GIME, which is probably the key hurdle remaining that prevents a real CoCo (which means at least partial DECB as well as OS-9) accelerator from being developed. 

Hopefully you're talking about a floppy controller that would work properly with 5.25" 1.2MB and 3.5" 1.44MB drives. I'd expect nothing less from you, actually! As long as it will at least properly read 5.25" SS/DD floppies that would be fantastic! It's hard to get those old drives, but there are still loads of software on the discs. Eventually that will get processed onto newer media and into .dsk or other image files, but in the mean time there's still a need for many to be able to at least read the old disks. Of course any modern floppy controller chip should be able to do just about any floppy drive, including the obsolete variety, though I think some of the newer ones won't do anything less than 720K drives... but that may just be in the more recent PC BIOS, not the controller.

Frank,

Sounds like you are describing the SuperIDE board with HDB-DOS. As it emulates the floppies on a hard disk. Now if you are saying you actually want a floppy drive interface, physically then....have you tried to get 5.25" 360k drives in quantity lately? Uggggghhhhhhh. Nope, we don't design to old technology, think bigger. I'll leave it as that.
