I cannot take any decent pictures of my JX-10 right now. Here it is, going through major brain surgery, learning new tricks... 

   

This machine has got a BIG SOUND. I will never part with mine. It's got some quirks, though. First, its MIDI implementation is really CRAP, even to 1986 standards. You cannot edit your tones over MIDI, and you cannot even do Sysex bulk dumps without a RAM cartridge. But I'm working on this. 128 patches available at the same time is not enough. But I'm working on this. And editing the sounds without a programmer, using only the α-dial is not for weak. But I'm working on this as well. All this does not count considering the SOUND.

If someone's interested, here's the list of all startup messages you can arouse:

During power on, pressing and holding... ...brings forth this:
nothing ****** ROLAND JX-10 ********
D and H 'JX-8P PROGRAMED BY AKIRA MATSUI' (original spelling!)
H 'VER 2.30 87/8/ 6 <MAIDO ONAJIMI>' (may vary depending on your firmware version)
D ' THANKS ERIC & ADRIAN ' (this of course refers to famous Eric Persing and Adrian Scott who were the factory sound designers for JX)
A, B, D, E and H ' PROGRAMED BY TAKAHARU FUKUI '
  ...or a test mode:
A, B and C Check for the presence of a special development cartridge. If present execute the code in the cartridge.
A Test Mode #1: Skip Voice Board diagnostics, reset Master Tune and Controller settings. Skipping diagnostics speeds up the boot process a lot, from 13 seconds down to 0 on my machine.
B Test Mode #2: Indicate voice assignment with panel LEDs in the following order:
MIDI -> TONE -> PATCH -> DUAL -> SPLIT -> WHOLE
C Test Mode #2A:
E Test Mode #X: During COPY CARTRIDGE TO INTERNAL MEMORY all data bytes are echoed to MIDI OUT. Probably a design time hack that was forgotten to remove. 

You can find any information about JX-10 available on the net on the excellent Super JX Zone website which is a compulsory reading for anyone seriously into JX-10.

NEW! Recently a nice article from 1986 about JX programming (written by Eric Persing himself!) was looking for good home. You can download it here. A scan of an  accompanying ad from the same magazine hides here.

 Any comments and suggestions are, as always welcome.

(*) This is the maximum one could get. Well deserved.

(**) 56 without programmer. PG-800 would have given 67.
