Vintage VIDC Enhancers

Watford Electronics VIDC Enhancers

Watford produced two VIDC Enhancers based on the same PCB. Both of these devices were controlled by the I2C protocol and only differed in the fact that one contained only a 36MHz oscillator and the other contained both a 25.175MHz and 36MHz oscillator.

I've fully documented the 36MHz version of the Watford Electronics VIDC Enhancer on its own page.

The photo below shows a variant of a VIDC Enhancer which is mounted in a similar way to the Watford Electronics VIDC Enhancer in an A410/1. The enhancer appears to be a 36MHz only model with the oscillator mounted on the underside of the PCB and the control chip mounted on the top side. The grey wire is the control wire which connects to the AuxIO connector.

Beebug VIDC Mode Expander

The photo below shows quite possibly the smallest VIDC Enhancer ever made. The oscillator is on the underside of the PCB and the control chip is surface mounted on the top side. The device is a Beebug VIDC Enhancer. This VIDC Enhancer is fitted to an original Archimedes A440. The red and black wires leading off to the bottom left of the photo are the control wires which connect to the Aux IO connector.
