Yes.

no

A periodic interupt, 100 hz is good.

Memory: at least 1/2 megabyte for a general purpose system single user
system.

Avoid perepherals that monopolize the cpu for long periods of time,
such as bit-banger serial.  Interupt driven i/o is recomended,
dma disk i/o is preferable.

dsdd 96tpi non-hidensity ("720 k") is most popular in 5" floppies, you
can read/write most other 5" formats.  You may also want to get at 3"
floppy drive for exchange with atari ST owners.  (I have both.)
