Looking for the MCS-48 firmware of this Apple ][ clone keyboard...

Looking for the MCS-48 firmware of this Apple ][ clone keyboard which to my shame I fried more than a decade ago by connecting its ribbon cable rotated by 180 degrees into the socket. It recently came to my mind and after a vague research I discovered that the controller was some version of MCS-48 Intel family which could have been read without code protection in 99% of the cases. But back then I had neither programmer nor the knowledge that this keyboard was good to preserve the firmware of so widespread MCU...In case I obtain the firmware I would be able to send for free programmed chips to all supporting people that would like to have spares. Some of you know that I already did this several times in other occasions for members of this forum.
