[sdiy] DX7 hacking?

[The Old Crow]

   A dozen years ago I made a re-spin of the Grey Matter E! board, which 
I rather obviously called the RE! board for the original (and much 
better built) DX7.  I applied a small code hack to the ROM to show my 
name in the power-up portion of the display.  You had to find and tweak 
the checksum of the firmware when changing the text field for the 
power-on display message.  The only other thing I did was change the LCD 
to an LED-backlighted one.

   You are probably asking about synthesizer engine hacking.  There is 
someone in the UK who was good at that, he sent me that French E!-like 
board long ago.  I'll dig up their email--if it is still active.
