Någon som vet vad detta är?

Gick igenom lådan med reservdelar till gamla Arp. Men vet inte vad det är och till vilka maskiner de hör. Någon som kan hjälpa mig identifiera?

Detta är snyggt!

"3.5.6 E'MODULE
The E' Module accepts the guitar signal from the Audio Multiplex Circuit (MUX, pin 17) and extracts from it a pulse wave (CLK and CLK). This clock output (at the frequency of the guitar string) is sent to the D board for processing. The three bit string code from the String Select Circuit is supplied to pin 13, 14 and 15 so that the circuit can 'set up' for the open string frequency of the guitar signal it is to receive. The clock output (CLK, pin 23) is also sent to the Limit Detector Circuit to generate Transfer (XFER) and Clear (CLR) signals. The level signal from the E' Module goes high to confirm that an extracted signal is appearing on the clock output.
The CV input (pin 6) comes from the output of the D' Module and is used to adjust the E' circuit to the pitch which is being extracted. After an initial pluck, the TRAIN signal (pins 10, 12) causes the E' Module to ignore temporarily the CV input until a new pitch has been extracted and processed through the D board.
The Q GATE inputs (pins 20 and 19) instruct the E' Module to begin extraction."
