Halting Problem module, 75x200 mm, with four knobs, two switches, and twelve jacks

This is a voltage processor module based on designs by ARP and MFOS.

There are two sum sections: One has four inputs, two with attenuators (normaled to -10 V and +10 V) and two with fixed unity gain; the other has two inputs, one with attenuator (normaled to +10 V) and one with fixed unity gain. Each sum has two outputs, normal and inverted.

There also is a lag processor section. Switches allow selection of slow or fast ranges and RC or linear ramping, and a knob adjusts the lag time.

The sum sections are derived from the ARP 2600 schematics. The lag processor is based on a section of the MFOS Multi Function Module .
