     It depends.  Better drives (double sided) can be bought fairly
cheaply and you can buy a 2nd source controller and case and power supply
and make a much better drive system, but it'll cost more overall and
servicing is a problem.  This is generally better for experienced
hardware hackers.

     It can be done either through the bit-banger port or the RS-232 Pak.
I'd prefer to use the RS-232 pak myself because it reduces processor
overhead and therefore speeds up your system a bit.  If you use the
bit-banger port, you can still have printout capability by attaching
your printer to the terminal (on at least some terminals).
