Marx Series 300 Electronic Bowling Game
|
||||
Main board:
|
||||
* TMS1100NLL MP3403 DBS 7836 SINGAPORE
|
||||
* 4*SN75492 quad segment driver, 2*SN74259 8-line demultiplexer,
|
||||
2*CD4043 quad r/s input latch
|
||||
* 5 7seg LEDs, 15 lamps(10 lamps projected to bowling pins reflection),
|
||||
1bit-sound with crude volume control
|
||||
* edge connector to sensor board, inputs, ...?
|
||||
|
||||
10 lamps for bowling pins + 3 more bulbs, and 7segs for frame number and
|
||||
scores. Board size is 10-12" by 6-8".
|
||||
lamp translation table: SN74259.u5(mux 1) goes to MESS output lamp5x,
|
||||
SN74259.u6(mux 2) goes to MESS output lamp6x. u1-u3 are SN75492 ICs,
|
||||
where other: u1 A2 is N/C, u3 A1 is from O2 and goes to digits seg C.
|
||||
|
||||
some clues:
|
||||
- it's from 1978
|
||||
- Merlin is MP3404, Amaze-A-Tron is MP3405, this one is MP3403
|
||||
- it plays some short jingles (you need to be lucky with button mashing)
|
||||
u5 Q0 -> u1 A4 -> L2 (pin #2) u6 Q0 -> u3 A4 -> L1 (pin #1)
|
||||
u5 Q1 -> u1 A5 -> L4 (pin #4) u6 Q1 -> u3 A5 -> L5 (pin #5)
|
||||
u5 Q2 -> u1 A6 -> L7 (pin #7) u6 Q2 -> u2 A3 -> L11 (player 1)
|
||||
u5 Q3 -> u1 A1 -> L8 (pin #8) u6 Q3 -> u2 A2 -> L12 (player 2)
|
||||
u5 Q4 -> u3 A2 -> L3 (pin #3) u6 Q4 -> u2 A1 -> L15 (?)
|
||||
u5 Q5 -> u2 A6 -> L6 (pin #6) u6 Q5 -> u3 A6 -> L14 (?)
|
||||
u5 Q6 -> u2 A5 -> L10 (pin #10) u6 Q6 -> u1 A3 -> L13 (spare)
|
||||
u5 Q7 -> u2 A4 -> L9 (pin #9) u6 Q7 -> u3 A3 -> digit 4 B+C
