[Coco] High(Er) speed cassette loading.

[Arthur Flexser]

Yes, 1500 bps was the stock speed of cassette I/O.  In high speed mode,
this would be approximately doubled.  Not quite doubled, I think, due to
the fact that ROM routines were at double speed but the RAM accesses
weren't, in the CoCo 1 high-speed mode.
