Cub Conversion: Difference between revisions

Thus the plan was hatched to create a new monitor bank for the station using 18 of these monitors (three rows of 6) to display all the important live video signals to the control room. The monitors were relatively cheaply and easily available second hand, so accumulating a set was not a problem. The snag was that the model with a composite video input suitable for connection to the studio was almost unheard of, with most purchasers having opted for the basic model with only an RGB input at TTL levels, suitable for connection to a BBC micro but almost nothing else. This problem was solved by the construction of an adaptor board that could be installed into the back of the monitor to perform the decoding of the composite video signal into it's RGB components to be fed into the monitor. The RGB input was disconnected, as they were intended only for use as video monitors.

This circuit was created by [[Rob Sprowson]], and a set of 18 duly created in {{unsure|2000 or so?}}, together with a new, steel monitor rack sized so that the monitors would fit neatly on it. The station mains wiring was upgraded so that the wall behind the rack had enough mains sockets to plug everything in directly (see the [[G/046]] page for the tale of how this was done]], and YSTV could now see every point of the vision path in colour. The old black and white monitors were cascaded to become part of the [[NaffoCue]] system.
