via this auction

"there were mods done to her:
1. Keycode Input (SK30 or SK50D connector) on the back was removed - done by org. owner
2. PGM lock (program write lock/unlock switch) was replaced w/ additional L/R outputs - never tested 'em but if i remember correctly these outputs bypass VCA or VCF of the synth. (sorry may be wrong here) - done by org. owner
3. MIDI interface by Kenton was added by a Pro from "A Sound Education", a shop here in Chicagoland.

they also turned her inside out to check for any problems: "Feet I" slider was cleaned and re-soldered, program switches 11 & 14 in row 1 were replaced. midi was implemented and tested. no other issues were found."
