This is a Atari ram cartridge with 128KB static ram memory, who keep its contents with a 3v lithium battery. Has a special ram bank switching fully compatible with Atari XEGS, and can be load all these 32/64/128KB games. Also can load standard 8 or 16 Kb games.
Apart from this (one game -.rom or .bin- at a time) someone can load a collection of games until reach the maximum ram of course. This can become with the use of a special loader from them, within Windows. The files who supported in this case is atari binary files like *.com, *.exe, *.axe. *.xex, *.obj, *.bin etc. Loader adds a menu with a list of the games to choose.
A third option is to use as a backup RAM cartridge, but it need the use of special patched version of DOS II.+.
I have test this cart both on XL and XE computers, and run perfectly not only for games but also for Diagnostic cartridges, this one who used from Atari service centers.
I ask 22 euro
plus shipping cost for new and complete cartridge. All the construction made by me.http://raster.infos.cz/atari/hw/ramcart/ramcart.htm
