| Popeye 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 you will usually
just see the powerup garbage on the screen. This garbage is just the random bits
that are in the character RAM at powerup, and it indicates the CPU was not able
to run.
Another common mistake is for the Z80 CPU to have been inserted incorrectly,
either backwards, or possibly with a pin bent that did not insert into the
socket properly.
Power On Self Test (POST)
| The Popeye high score save kit will perform a very simple
powerup selftest of the HS daughter cards on powerup. The results are
displayed briefly before transitioning into gameplay mode. |
 |
| If the powerup selftest fails, a message indicating the
failure will be displayed on the screen.
A sample screen showing the failure is shown to the right. If you see
this failure, 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.
