I uploaded the firmware for the Mex-8000 I just picked up. Talk about 
sparce code the 2764 is mostly empty space. Maybe this can help out 
someday with decoding sysex transfers for all these different synths. 
The 3 dip switches (4 position) on the back hard code for each 
different model, midi channel, and memory protect for each of the 4 
memory banks.

Without using my Poly-800II I had to fool the Save by sending the bank 
from Midiquest as soon as the Save button was pressed. Using Midi-Ox I 
can see the Mex-8000 sends a dump request to the synth. Then after the 
midi transfer the Good light lit for a few seconds. The load button 
would then send the saved bank and the good light flashes again after 
the transfer. Neat little setup.

Has anyone ever seen any more info on this unit? I would like to find a 
manual somewhere to scan if necessary.
