Berzerk, Stern 1980 ------------------- The complete boardset includes these 6 boards: ZPU-1000 [CPU/ROMs] SB-1000 [Amp] VSU-1000 [Sound/Voice] BSC-1000 [Video] VFB-1000 [Video + Controls] RCR-1000 [Interface Board to controls + video] Here is the board layout: If you lay down the boards exactly like the diagram, all the game bus connectors align themselves. The games bus connectors are all 23-pin small-width MTA connectors, except for two 18-pin small-width MTA connectors at locations J3 and J4 of BSC-1000 and VFB-1000. ------------------------------ | ** ** | | J6 J5 | | | | ZPU-1000 | | | | J1 J2 J3 J4 | | ** ** ** ** | ------------------------------ || || || ------------ ------------------------------ | ** | | ** ** | | J2 | | J7 J8 | | | | BSC-1000 | | SB-1000 | | J1 J2 J3 J4 | | | | ** ** ** ** | | J1 | ------------------------------ | ** | || || || || ------------ ------------------------------ ------------ || | ** ** ** ** | | J1 J5 | ------------ | J1 J2 J3 J4 | | | | ** | | | | J2 J6 | | J1 | | VFB-1000 | | RCR-1000 | | VSU-1000 | | | | J3 J7 | | J2 | | | | | | ** | | | | J4 J8 | ------------ ------------------------------ ------------ These pinouts are for all the large-width MTA connectors on the game boards.

Miscellaneous Notes ------------------- The game switches are also numbered from 1 to 40. Bank F2 switch #1 is switch #1. Bank F3 switch #1 is switch #9. Bank F4 switch #1 is switch #17, and so on. Signature Analysis Mode ----------------------- See the "Stern Video System 1000 Signature Analysis Manual". Switch Test ----------- Displays open or closed position for each DIP switch or Game switch. You do not have to power the game off and back on to see the switch test. Set switch #9 (Bank F3, switch #1) to ON and press the RESET button (switch #1 located at F1 on the ZPU-1000 board). The monitor will display the off ("O" on the monitor) and on ("#" on the monitor) status of the 40 ZPU DIP switches on the upper chart and the open/closed status of all game switches (buttons/joystick/coin mech) on the lower VFB switches chart. You can test DIP switches and control switches by switching them off and observing whether they show up as off in the monitor chart. To return the game to normal operation, turn switch #9 OFF and press the RESET (SW #1) button on the ZPU board. Here is a diagram of the charts you will observe on the screen: ZPU Switch Status ------------------------------------------------------------------------- |1 |2 |3 |4 |5 |6 |7 |8 | |Normally|Normally| | | | |On for |On for | Bank |OFF |OFF | | | | |Extra |Extra | F2 |On for | On for | | | | |Man at |Man at | |SA tests|SA tests| | | | |5,000 |10,000 | |--------+--------+--------+--------+--------+--------+--------+--------| |9 |10 |11 |12 |13 |14 |15 |16 | |On for |On for | | | | |Coinage |Coinage | Bank |this |Cross- | | | | | | | F3 |display |hatch | | | | | | | |+ RESET | | | | | | | | |--------+--------+--------+--------+--------+--------+--------+--------| |17 |18 |19 |20 |21 |22 |23 |24 | | ------- Coin Mech #1 ------- | | | | | Bank | | | | | | F4 | | | | | | | | | | | | |--------+--------+--------+--------+--------+--------+--------+--------| |25 |26 |27 |28 |29 |30 |31 |32 | | ------- Coin Mech #2 ------- | | | | | Bank | | | | | | F5 | | | | | | | | | | | | |--------+--------+--------+--------+--------+--------+--------+--------| |33 |34 |35 |36 |37 |38 |39 |40 | | ------- Coin Mech #3 ------- | | | | | Bank | | | | | | F6 | | | | | | | | | | | | ------------------------------------------------------------------------- VFB Switch Status ------------------------------------------------------------------------- | | | | | | | | | |On when |On when |On when |On when |On when | | | | |joystick|joystick|joystick|joystick|fire | | | | |left |right |up |down |pressed | | | | | | | | | | | | | |--------+--------+--------+--------+--------+--------+--------+--------| | | | | | | | | | |On when |On when | | | |On if |On if |On if | |start 1 |start 2 | | | |coin |coin |coin | |player |player | | | |mech #3 |mech #2 |mech #1 | |pressed |pressed | | | |closed |closed *|closed | ------------------------------------------------------------------------- * = if used Crosshatch Pattern ------------------ Used for monitor setup. Pushing the fire button will cause a red screen to check purity. Pushing the fire button again will cause a return to the crosshatch pattern. Bookkeeping ----------- Inside the coin door is the BMDS (Bookkeeping Monitor Display Switch). Depressing this switch one time initiates this function. The first book- keeping function to appear on the monitor is number of credits (*Green). To delete from memory, press either fire button. Depressing BMDS one more time will advance the bookkeeping up (*Blue), and the second bookkeeping function (total coins through coin mech #1) will be displayed on the bottom (*Green). To delete from memory press either fire button. The previous bookkeeping functions will remain on the screen (*Blue) and the new function will appear on the bottom (*Green). Bottom function can be deleted from memory. Following is a complete list of bookkeeping functions. * = Color of display if color monitor is used.
