Subject: Reading from the Serial ULA

The serial ULA has one (apparently) write-only register.  As I'd kind of
expect, reading from this register returns zero.

However, if I turn the cassette motor on (which effectively sets bit 7
of this register) and then read the register again, I get the value zero,
but the cassette motor is turned back off.

Can anyone explain this bizarre behaviour ?

James.
