ARP 2500 - 1026 Preset Voltage Module

The 1026 is a rare module. I think only a few were produced and Ive never seen a original
though there are a few reproductions around.
Probably the year of production of the originals was about 1970 ???  
 


There are 16 preset voltages : 2 rows of control voltages 
each holding 8 individual CV values.
You set their value with the pots.
You trigger the CVs by pushing the associated momentary button
or with a 10V gate. (at lines 1 to 8).
The output voltages appear at lines 9 & 10.
Pretty simple.
The manual suggests using this with the 1027 sequencer or 1050 Mix-sequencer.
There is a socket at the rear of the unit to connect to a 1027 or 1050.
 
Specs:
Output voltages: 0 to +10V
Output impedances: 1K ohms
Input impedances : 100 K ohms
Power requirements: +/- 15V @ 20ma , regulated to +/-0.1%

 
 
 
 
 
 

It reminds me very much of the Serge programmer.
I have of course, rotated the pic to illustrate my idea.
I wonder which module came first?

The programmer has evolved into many forms today.
Think Makenoise pressure points & 0-control 
or Synthwerks 4x4
