[uk-vac] Tech: Microvitec 1438 combining sync
Hi

Does anyone know which chip i need to combine the sync signals on a
microvitec 1438 monitor for use on a test rig.

At the moment i get picture but its rolling im told i need to combine
the sync to resolve this problem.

Any help greatly appreciated.

Setch.

P.S its about time ukvac died and someone opened a new one - good job

Andy,

Try going here:-

Scroll down and find a great circuit using a 74LS86 and a few other
bits(or do it easier provided you know the ploarity the H an V syncs).

Cheers,
Dave.
