Opening Up an Ensoniq ASR-10 or TS-10 Keyboard
Place the keyboard face down on a couch, bed, or other soft surface, with the keys pointing away from you - and of course, with nothing plugged in
(especially the power cord!). You will need to remove the bottom panel, which will require removing lots of screws from the
bottom and from the back of the keyboard. Note that there are different types of screws used to secure the bottom panel.
Along the front edge of the keyboard are coarse-thread screws, so keep these separate. The screws in the back panel and along the edges of the bottom
are all identical machine screws. On the ASR-10, the two screws on the bottom panel that are underneath the top-most "A"
note are yet another type, slightly smaller than the others. So make a note of which screws go where!
Once all of these screws are removed, you should be able to lift off the bottom panel. (You do not need to remove the screws holding the small trap door on the bottom panel of an ASR-10, where you access the SIMM memory.)
