Asteroids    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 Asteroids 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.
