New Atari 1040 STf Owner-Keyboard beeping nonstop

Postby dave5678 » Wed Jul 10, 2019 9:01 pm

I've tried everything I could think of. I did buy a new buffer chip since they are so cheap. Should be here tomorrow. I also attached a video of this posted on another forum. https://atariage.com/forums/topic/293039-current-issue-with-1040stf-video-attached/

Any ideas on the cause are greatly appreciated. I just really want to play my first Atari ST game, :D ! Thanks a ton everyone.

Hi Dave,

Cause maybe:
1) Key that remains depressed or contact during circuit (oxidation).
2) The Buffer
3) The MCU on keyboard
4) The ACIA chip (6850) on montherboard

If you have another keyboard, to do the test, it eliminates the 3 three first point.

Thanks
Olivier

If you bought it like this, I'm willing to bet that a former owner spilled pop or something over the keyboard.

This is most likely remedied by taking the keyboard apart and givi it a thorough cleaning. (It's not hard, just time consuming due to the number of parts... )

And unless I am mistaken, this could also be sign of keyboard cable beeing detached from motherboard.

check for broken wires where the wires fix to the white plug on the keyboard
