Title: Help needed with A87 Vo.2 PCB
Post by: kaiserreich on Sat, 18 August 2018, 07:51:22

Hi Folks,

I need some help with reprogramming the A87 Vo.2 PCB.
Half the left matrix of the keyboard is showing up as another key.
If I press the Esc key, the \| key shows up.
Pressing F1 / F2 / F3 / F4 shows up as another key.
The same applies for A S D F ....basically the left half of the keyboard.

I tried reflowing some of the affected diodes and switches but that did not help. I am suspecting the firmware being corrupted, and hopefully a reprogram can help it.
