I have been looking for a second compatable SX-1 for two years with no luck. So I may consider selling mine and moving to a different platform. Standard machine with 1.50 OS, 60GB internal HD, Antares, SCSI out, factory Tascam shipping box with all internal bracing. All documentation. Bought new as a demo from Full Compass. Overall excellent cosmetic condition, one minor scratch on arm rest. Three (3) Analog cards installed. Has horizontal lines through LCD screen (I use external VGA). This machine is happier when it remains on; it takes awhile to boot if it sits unused. If interested please PM me at email@example.com.
