Universal CPU and camera. Specs are same as ST-5c (see www.sbig.com) except this does not have internal color filter wheel ability and it uses a serial port instead of parallel. Works great as either primary camera or autoguider, or both.
Package includes sbig serial cable, sbig macintosh serial cable (if you want it), 25' serial extension, original CCDOPS software disk (download the latest from sbig), autoguider cable (currently wired for skysensor2000 but easily rewired - I'll do it if you don't want to), AC adapter, original ST-5 manual and CCDOPS manual.
Asking $500 plus shipping.
