"SLAM" from Mirco Games (1975)
Hi,
just working on repairing the PCB Set for this table "SLAM II" from Mirco Games in 1975 :

BTW I seem to have verion SLAM II (not just SLAM) with the MODE Select Switch and Start Pushbutton on top of the table.
Its a 'PONG' extension for four players and Paddles can be moved across the playfield vertically and horizontally. Repair is a challenge with >100TTL Chips and no schematics. Have worked my way with the help of an HP logic comparator HP10529A and replaced some faulty chips, still not there, as collision detection with the paddles isn't working.
Have also identified all chips but one....
Is anyone recognizing the Chip in the middle of the small picture " 542 7529" ?
It may be a sort of monostable multivibrator, as the outputs are changing their duty cycle with paddle movements and caps/resistors are connected to it.
Thanks
