[Coco] Stand-alone DriveWire devices.

[alsplace at pobox.com]

It dawns on me that there must be some really cheap PIC-type 
programmable device with memory storage and some programmable CPU.  
Some of these gadgets are very cheap.  If there was such a device, it 
might be interesting to make a standalone "DriveWire" hardware unit 
that could just plug into a CoCo's serial port.  Anyone out there 
familiar with the state of the art for BASIC STAMP or PIC type chips?  
It would just need to have a fast serial port and some form of backed 
up memory (flash, battery backed RAM?).

Thoughts?

Also, is there an unofficial HDB-DOS that speaks DriveWire instead of 
SCSI/IDE?
