Challenger 2P

Challenger 2P

 This system is composed of separate boards including a 502 CPU board, a 540 video card, and a keyboard all mounted in a thin case. With a newer graphics card than older Challenger 1P system, featuring a whopping 2K of video RAM, a 64 x 32 character display was supported. The system featured a four-slot backplane (hence the "4P" designation) of which only two cards were installed in the basic (cassette-based) system allowing further expansion with RAM and floppy-controller cards. The "2P" label identifies this as an older unit (originally branded "2P-4", later "4P").
