   i have been wanting to get a hard drive for my 500, but i am much too
cheap to buy one.  i have come up with a solution and i wanted to bounce
it off of the world for comments and suggestions.  a friend of mine gave
me a 10meg miniscribe 2012 drive for an ibm a few weeks back, and a
light bulb came on in my head.
   my idea is to buy a cheap ibm motherboard (and the appropriate memory,
controller and serial/parallel cards) from a cheap source (like a
hamfest or electronics flea market).  i want to turn the ibm into a file
server running over the parallel or serial lines. i know, it will be
slow, but speed is not a key factor here, CHEAP is.  i am planning to
write a device driver on the amiga side that makes the ibm look like a
regular disk drive.  the amiga will send a packet with track and sector
information along with a command (r/w/?).
   on the ibm side, a fileserver program that will read the track/sector
and send a packet of data (maybe with a primitive
cache) and whammo, a cheap hard disk!  the total cost should be under
$100.  $5 for the power supply, $5-10 for the motherboard, $5-10 for the
par/ser card, free hard disk, borrowed (free) controller card (xebec),
$25 or so for the miscellaneous cables, $?? for memory.  the development
will be done on a friend's ibm, so i MAY not need a keyboard or
monitor card.
   now i ask: what do you think? will it work? does anyone have a device
driver that may work (or help)? has anyone ever done this before? does
anyone have any better (cheaper) alternatives? suggestions? warnings?
   any resposes will be appreciated.
