These are the legendary (better-than-E!)
expansion boards
for the original DX7. Here is a brief explanation of the expansion:
Memory expansion to 512 voices (16 banks of 32) & great new functions
32 "Factory" sounds utilizing new SuperMAX features
16 note x 1 voice normal polyphonic mode
3 powerful Stack modes (8x2 or 4x4 or 5x3) with detuning, chords, octaves, etc.
Multi-mode Arpeggiator - the most sophisticated ever
Custom "Sound Creator" voice function
3 independently assignable MIDI keyboard zones
On-board Delays to 9.7 seconds, with 15 variable repeats
User defined chromatic and fine tuning
Compatible with standard RAM and ROM cartridges
No soldering (unless you add the battery holder, see below)
SuperMax+ v2.40 includes a few improvements over the original SuperMAX:
Licensed from the original developer. Not a ripoff or clone.
Mounting hardware for securing the board.
REV B:
Double Precision Velocity. Twice as many MIDI out velocity levels. More subtlety. More dynamic.
new!
REV B:
Hardware "velocity fix" switch located on the board: "normal" and "+3" for full velocity output on MIDI.
new!
Minor user interface improvements and bug fixes. Also, much cuter bold splash screen: "Super
MAX
+"
[Included option] Battery holder included so your tech can add this next time your battery needs changing (requires experienced soldering). Standard holder for CR2032.
New (rewritten) manuals.
The New Installation Manual:

It's step-by-step and all you need is a couple of screwdrivers.

*This quote is from Yamaha. Please remember that the DX7 is not at all intuitive. If you are not confident with it we do not recommend adding an expansion of any kind until you are:
WHEN ALL ELSE FAILS, READ THE INSTRUCTIONS
The DX7 is a deceptively simple looking instrument, one which has many functions that are not obvious at first glance. We realize this is a long manual, and there is a strong temptation to skim over portions of it or skip them altogether. If you are having difficulty, we urge you to spend a little time re-reading the appropriate sections of this manual to make sure you understand how the instrument is supposed to work.
