| Battlezone High Score Save
Kit -- Trouble Shooting |
A common mistake is not having the daughter card inserted correctly, either hanging
over the socket by 1 pin, or in backwards. In this case the screen will be blank
and the start LEDS are probably lit.
Another common mistake is for the 6502 CPU to have been inserted incorrectly,
either backwards, or possibly with a pin bent that did not insert into the socket
properly.
| The Battlezone high score save kit will perform
a very simple powerup selftest of the HS daughter card when the game is
placed in selftest mode. Two additional lines of text are displayed during
selftest that relate to the HS kit. The first line either displays "ROM
FAIL" indicating that the eprom on the daughter card is defective, or it
displays the rom revision (eg. "REV 2A"). The 2nd line displays information
about the HS save chip on the daughter card. It displays "HS FAIL" if that
chip is defective, or it displays "ERASED" if all the scores have been erased,
or it displays nothing if the chip is functioning properly. Should you see
the text HS FAIL during selftest it most likely that means that one
of the socketted chips on the daughter card is probably lose. Check to make
sure the 8 pin dip (the smallest chip) on the HS daughter card is fully
inserted into its socket. |
