Peter posted this a while back:
The new 15A Expander adds functionality to the M15 and a direct result  
of customer
requests. It connects to the Rev.2 VCO via a dedicated I/O connector  
located on the back of
the PCB. It can however be retrofitted to any Model 15's regardless of  
revision, although
earlier releases (rev 1 - 1.6) will require point-to point  
connections. the 15A is only 4 HP
wide and adds a PWM attenuation pot, a Soft/Hard Sync crossfade pot  
(which amplifies the
M15 sync function up to x4 it's previous intensity), 3 three way  
transposition switch
(configured octave up/none/octave down) and two additional 1V/oct VC  
inputs. The 15A will
begin shipping at the end of May 2007 with a retail price of $70.
