The most important things (NC200 and Lapcat support) are in the
README, under `Future developments'.


The X versions should probably unpress all keys when they lose
keyboard focus. Isn't likely to be a huge problem in practice though.


There's a strange bug to do with serial input when running bbcbas,
which I haven't yet been able to figure out - see BUGS section in the
man page.

(I *think* this may be due to bbcbas keeping interrupts off so much
(IIRC). This probably means that, since it'll keep trying to interrupt
every instruction, serial_input_pending() gets called a LOT. Slightly
tricky to fix though.)
