HISTORY:
Remember CRT based monitors & displays? These chips were used in the multi-sync type of monitors and displays, both in the domestic and industrial markets. We had these on hand for servicing of the very large screens (often Mitsubishi or Hitachi) used at the airports to display flight information - remember those monsters? Of course they still have the very large screens but nobody is using CRT based displays these days.
These chips come from that era (around the early 1990's) and are only going to be of use for someone who is restoring an old multisync monitor for 'historical' reasons. No contemporary monitors would be using these chips.
Straight from my "vintage spare parts" section of the old workshop stores, these are NEW devices, but of course very old stock
