It has been upgraded with the following modifications:
Rambo XL 256K
800XL OS (1200XL function keys still supported, 100% XL/XE compatiblity)
Internal Basic
Dual-Pokey stereo upgrade with audio out L/R RCA jacks
SuperVideo 2.1 upgrade to RF, composite and S-video (chroma/Luma; still requires monitor cable or break-out-box for composite and S-video output)
SIO port +5v&ground upgrade
Power pack and upgraded NTSC 1200XL only, no cables like monitor, audio or SIO included. Intended for a collector with an XL system who want to upgrade just the computer, but of course anyone is welcome to purchase it.
Pictures below including YoomP! title screen showing STEREO enabled and Commando loading screen to show 256K (192K extended+64K base) memory, and Commando game screen to show it working. Unfortunately pics are too blurry to show the sharpness of the SV2.1 video upgrade though...I tried and just couldn't get sharper pics of the monitor screen.
$150 includes shipping in U.S.
Thanks for looking! PM me if interested.
