This unit is complete with the MU-1 Mouse + a TANDY CM-11 RGB colour monitor (w/ specially made RGB cable and adapter that was like almost 50$ just for them itself!).   It is a dream to be able to edit the samples right on a colour monitor!   This unit is in Beautiful shape and has ALL the manuals and also a Patch Book (a nice 3 ring Binder)  that I made to keep track of the 150 PLUS  (WOW!)  disks of samples.  And a CD I burned with all sorts of editing tools for the PC, different versions of the Operating Systems for the S-550, more patches, etc etc!
 It also includes the CD-5 Boot OS (also on floppy) which includes the Utilitys built in, ( I have extra copys of that on floppy as well as backed up on the cd). 
$550 (plus shipping).  There is TONS of stuff.. This will be more the one box to send! The ONLY reason I am selling it is because I urgently need to replace my synth module . So if you have one that interests me  I would consider a trade offer.. plus shipping!
 I am not parting this system out.. SO PLEASE DONT ASK!  Any questions please email me  at
