  Five functions in one box give your 800XL or 130XE the leading edge in
performance and execution.

  1)  RAMdisk:
                Choose from two versions; 256K or 1 MEG.  Built in software
                allows the RAM to be partitioned into multiple disks as
                desired.  The Multi I/O has its own AC power supply which
                allows the RAM to retain its memory when the computer is off.

  2)  Parallel Printer Interface:
                A 'centronics' type parallel interface which uses a standard
                850 cable.  Accessed as P1: or P2: with or without LF.

  3)  Serial Printer/Modem Interface:
                This port accepts either a serial printer or RS232 type modem.
                The 850 handler is built in; always there when needed, which
                means an extra 1800 bytes of free memory!  Built in software
                also allows a serial printer to appear as a parallel printer
                and provides it with XON/XOFF software handshaking.

  4)  Print Spooler:
                Use any amount of RAM as a print spooler.  Works with either
                of the specified printer ports.  Built in software features:
                Pause, Resume, Repeat Copies, Clear, and set spooler Size.

  5)  Hard Disk Interface:
                Supports up to eight SASI and SCSI controllers at the same
                time to use industry standard 5-1/4" and/or 3-1/2" hard drives.


   130XE owners will also need to purchase the "130XE Adapter".
