Yes. I'm considering putting the mass storage ROM on the I/O slot card
also (similarly to how the sector buffer works), but since that ROM is
hard-addressed, that won't actually free up the ROM slot it would
normally occupy.

Would use MicroSD cards.  One newly-designed module in the I/O slot,
which would talk to a small external box with four MicroSD sockets.  I
could actually consider having the box be able to talk to multiple
9830s in a manner analgous to what the 11305A controller did, but I
only have one 9830.
