Hardware/Software Combo For Atari 800

MEM/EX is a memory expansion device for the Atari 800 computer. It replaces the operating system board and includes 4K of low-power CMOS static RAM mapped to the unused $C000 address space.

Included with the board is a powerful command-extender program called COM/EX. This adds ten edit-mode commands to the standard BASIC or Assembler cartridges, including the most used disk commands.

MEM/EX is compatible with all standard Atari 800 configurations; COM/EX requires at least one disk drive and DOS 2.0. The package is available for $129.95.
