I believe is a 7 track assembly. Or look for one of their complete units MR-30, MR40 etc.
Might be a good starting point for building up
a reader. They are variable speed units also, with a wide range of speeds.
Ok, it looks like the top speed of a complete MR-30 is 38.1 cm/s, or 15 ips. That's
half the speed of a normal TU-58, but maybe it's close enough to get a good signal?
And maybe the mechanism can be driven faster? For $24 shipped, it's worth
experimenting with, and if it works, then that solves most of the mechanical hurdles.
Thanks for the lead!
