YAMAHA DX7 S
This DX7 was launched in late '87, early '88. After the original DX7 was replaced by the much improved II version, there was still a market for 'somewhere in between'. The DX7S bridges the gap between the old and the (expensive back then!) new DX7II.
It looks like this...
The casing is a sleek, black, lightweight alloy affair, making this DX7 weigh only 10.5kg - nearly 35% less than the original one!
This is very much a mark 2 DX7, albeit cut down. The DX7S will do everything the original DX7 can, plus more (better MIDI, sound quality etc)
The LCD is still a tiny 2 x 16 char dot matrix type, but at least it is back-lit (green). If you are buying one, check that all the buttons work - this style of DX7 is prone to getting dust under the contacts (not a big problem, only you might have to press some of them quite hard).
See The Difference
In the photo below, you can see the difference between an original DX7 (on the top layer of the stand) and the DX7S.
And that dodgy 1980's wall paper is still there!

The manual can be downloaded free of charge from Yamaha, so there's no excuse not to get programming!! You will also find a complete DX7S spec here too.
EBAY AUCTIONS, CLICK HERE
If your DX7S is broken, don't throw it away - even broken DX7's fetch some bucks on ebay auctions. There are still many thousands of DX users who want to keep theirs going, so sell your duff one for spares!!
If your DX7 seems to work ok, but doesn't produce any sound (and you've checked obvious things like volume!), then perhaps the LOCAL feature was turned OFF, which means the DX7 transmits MIDI but won't play it's own sounds.
To check / rectify this, after turning the DX7S on, press the EDIT / COMPARE button. Then press Button 31 (MIDI1) a few times until you see the word 'Local' on the LCD. For the DX7 to play it's own sounds, Local must be ON. Use the Cursor buttons and the + - data entry buttons to change Local to ON.
