The Sys-Check V2.2 BBU external device offers these major functions:

  • • Diagnostic tool for dead computers without the need to open the case
    • External O.S. (operating system) switcher (up to four O.S. can be selected by the user)
    • You can also put any standard ROM or EPROM containing Atari O.S.(s) in the DIP socket at Sys-Check’s PCB
    • External 512 KB Standard memory expansion using “RAMBO” scheme
    • CR2032 lithium battery for keeping the memory expansion’s content after power off
    • A write-protect switch to prevent the content of memory expansion from changes
    • All future updates of the diagnostic tools can be easily flashed into the Flashchip with an easy-to-use flash tool using your Atari XL or XE

Attention: Sys-Check BBU needs to run any XL computer with a PBI interface (all 600 XL and 800XL, but not the 1200XL) or any XE with ECI (800XE, 130XE, some 65XE, but not the XEGS). Some (mostly NTSC) XE models do not have an ECI, so Sys-Check will not work with these machines.
