This is EXTERNAL - if MUST go through the ports, so it can't even
be as fast as the hyperdrive.  The data, and access to it will be
solely limited by the serial port (real slow in terms of RAM).
(Unless, of course, the external ram is really a little Mac 
with out a screen :-))

Sorry!  That's what a REAL bus or SCSI ports are for!
