I left a note there about using CRCs to do data correction. It is a simpler method for software than normally use.
I posted a link on VCF about using GNU CRC RevEng--a great little utility to aid in determining polynomials and initial conditions for CRCs. Not too different from figuring oddball floppy encodings.
What I'd like to see is a QIC mechanical solution that treats DC carts as a reel-to-teel drive--no tension band worries. I imagine this could be done by motorizing the takeup and supply reels and putting in a driven capstan with suitable RPM control. Head positioning, of course, could be handled the normal way. Perhaps an old top-of-the-line audio cassette transport could be adapted.
