Keyboard Processor for Ensoniq ESQ-1, ESQ-1m, Mirage or SQ-80

This chip should not be here anymore but was found back today in a wrong drawer. It was accompanied by a new memory battery and a repair form describing the extensive repair needed on a botched ESQ-1, even missing its PSU. After these NOS parts were stored, awaiting the arrival of the machine, we never saw the owner again, who probably got cold feet because of the costs.
Now available for another fix, after several requests for such a chip where answered with "not available" during the last 40 years. Sorry folks, hope you found another one.!
Has been sitting on black foam all those years and the pins are therefore decently oxidised, but still a long way from interfering with the connectivity.
Rare chance to purchase this obsolete item.
