Hello everyone, I am new here and am getting desperate. I have a fully assembled Apple-1 with no additional capacitors or optimizations.
I haven't finished the "original" keyboard yet. I use the PS2 adapter or via VT100 with the Arduino/PIO adapter. With both adapters I get alternating characters on some keys. For example, with the key 2 (20202020...) or with the key . (.,.,.,.,.) I can't explain where this comes from. Basically, I have already changed everything. A friend of mine also has an Apple-1 with a similar configuration to mine and it works. Everything is also " default " at first.
Does anyone have any ideas?
