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.
