Description

This expansion enables your Atari 800XL, 1200XL, any XE or XEGS model to watch the newest demos or play the actual homebrew games, which often require more than the 64K main memory typical in the machine. This solution does not require drilling holes for switches; it’s software configured. 

The PCB is only 0.8mm thick and does not need the removal of any other parts to fit in all Atari XL/XE/XEGS computers (except the Atari 600XL). For some models and/or mainboard versions of your Atari, you need one or two 40 pin machine-head precision sockets to reach the required distance to other chips and parts. 

After power on, the 512 KB “RAMBO” mode is active. This mode should fit all your needs in 99% of all use cases. You can switch to 256 KB Compy-Shop mode (with separated ANTIC and CPU access) or switch the whole expansion off for some rare programs. These setting remains active until you power off the computer, a cold-start without power cycling won’t change the settings. 

The ANTIC and the MMU needs to desoldered and machine-head precision sockets installed. Just three wires must be soldered; a prepared cable for that is included. 

This SRAM based 512 KB memory expansion “Standard “(V4.4) works technically in all Atari XL, XE, and XEGS computers and will fit in the Atari 800XL, 1200XL models as wall as all Atari XE and the XEGS; however, it will not work in the Atari 600XL!
