Good evening all.
I have recently obtained my first Amiga. A simple A500 with a normal expansion.
Machine boots up fine, using Workbench 1.3 and it boots to Workbench fine.
I ran the Amiga Test Disk (latest one from Github) and all seems fine till I run the keyboard test.
The whole board is fine till I hit f7. That then also showed that I had pressed the Help key.
Continued checking and found that the cursor keys also fired off the 'P' column of keys on the keyboard. I also noted that the '7' on the numpad hits the '-' key on the numpad.
As the title says I've done a lot of repairs on other old machines (you can find me on StarDot quite a bit as the old BBC's are my forte and nemesis), so I pulled the ribbon cables out of the decoder (it's a Samsung keyboard) and then used a jumper lead to fire off the keys singly via the keyboard matrix and I could get the keys to fire individually.
With this in mind I believe the membrane was a bit iffy, removed the keyboard screws and had a good look round, separated the top from the bottom (leaving the middle sheet of plastic to separate the two halves) and gave it a wipe over with some contact cleaner. It all looks fine. Put it all back together and it was exactly the same.
Does anyone have any ideas where to go next?
