Subject: 6.15) What types of memory upgrades are there for the Atari?

This section by Andreas Magenheimer.

Just a short overview here, for a more detailed description (table), see
also 8.10 kinds of atari ramdisks (and 8.11 + 8.12 for programs that
support or require a ramdisk). The following memory enhancements do exist:
- Atari 400/800: ramdisks on memory boards, that fit into the normal
Atari 800 memory slots (Axlon and Mosaic types);
- Atari XL/XE: a) internal memory enhancements:
- piggy-back versions,
- professionel PCB versions,
- SIMM-module versions;
b) external memory enhancements:
- via XL-Parallel-Bus,
- via XE-Cart.port+ECI,
- Flash-ROM cart. versions,
- other Cartridge versions,
- RAM-Card versions,
- SIO-cartridge versions,
- ...
Note that many of these XL/XE memory enhancements are just hobbyist or
selfmade-projects. Most versions which use newer PC technologies
(Flash-ROM cart., RAM-Card, SIO-cart., etc.) are still under development!
