Faulty unit - almost 20 years old, so those electrolytics have to be prime suspects! I suspect it is "hooting", so the decoupling around the three terminal miniature regulators are currently under suspicion.

[later edit]

The electros all checked out fine, so without a schematic I decided to cut my losses and buy a replacement unit off Ebay for a tenner, including postage ...

Building version 2, six ICs down and tested. Including LM393 dual comparator and the two TS12A4514 analog switches from version 1, used to reset the integrators.

There is also now a 5V rail (on left) for powering the analog switches and the CMOS chips to be added. There won't be enough room on this breadboard for everything.

Update: This version has already been abandoned, because I forgot to include the multiplexers that "freeze" the integrators when required. Also, it's likely I will begin to use the Yamaha Y3014B floating point DAC for the integrator slope (coefficient) voltages, because they have important extra precision for small magnitudes.

You can still get these from jdr microdevices. This was the heart of the Vectrex video game system from back in the day (if you go to Video Games New York they still have one of these)
