Default Datasheet of Motorola's "SC10429" (SC 10429 Revox order code 50.05.0143) wanted

I need a datasheed of this mask perogrammable IC from MOT. This IC is used e.g. in the A-700 (A700), perhaps also in various other models the ReVox order code was 50050143.
Software/firmware therefore is easy to get in the meantime about

Maybe you already know all this, and you have some other, unusual plan for it, but I don't think the firmware would be useful. Being mask-programmable, it isn't like an EPROM or Flash ROM that "ordinary people" can program electrically. The program is put into it at the silicon fabrication stage.

It would be easy to write software for a modern PIC or Atmel microcontroller that did the same thing. To reverse engineer it, the schematic of the A700 will show what pins are inputs and outputs. Use of the A700 will reveal its operational logic - which is not very complicated.

Did anybody find a suitable replacement for this SC10429 ?
I think it must be possible to design a board with a static logic circuit...
