During the course of this discussion the original design parameters have
been lost, however to carry it to its illogical extreme...

The BEST solution to disk I/O is to buy a PC/XT clone (I've seen them for
< $80 including 20mb disk.) and run a program on the PC that looks for a
simple serial protocol from the PIC. My favorite is similar to the EEPROM
sending         <CMD><ADDRESS><DATA>
returning       <STATUS><DATA>

and ADDRESS is a 24 bit number specifying the address of the byte
and <DATA> is an 8 bit byte.

Now on a serial connection at any baud rate (up to the limit of the
PC's serial port) you can store and retrieve information from the
hard disk. Effectively making the PC a giant disk controller.

Of course its a ludicrous idea because why would you have the PIC driving
a PC and not the other way around?
