I agree completely about what drivewire has done for the coco! I use
it instead the CF card on my superide and avoid physical floppies whenever
and however possible! They're getting old and their reliability leaves a lot
to be desired these days.
If you're interested in getting a coco3fpga it's already possible. I got
my altera DE1 from Terasic for about $200 with shipping and the coco3fpga software
is available for free download.

That makes it a bit less desirable as a CoCo replacement, but since the CoCo can't connect directly to the internet I suppose another computer will always be necessary to some degree. I think it is still imperative that the computer be able to function without another computer. Emulating floppy and/or hard discs with the SD card slot is probably the best way to do that -- just not currently implemented. Maybe going through Drivewire (since that's built in, I think) to the SD card would be possible? Is there a way to detect when an SD card is present? I'm not familiar enough with SD card electronics to know. Would be nice if Drivewire could be programmed to look to the SD card when present instead of the serial port.

It would have to run a version of DW in order to work, so that would have to be ported/written, but that might be the easiest to implement stand-alone storage. Then one could plug into the SD card box or a regular computer. Or could something like this be programmed into the FPGA on the DE-1 board and use the SD slot already there??
