Yesterday I finished the cleaning of my Amiga 500+.
Last week I removed the battery and neutralize the acid from the battery with lemon juice.
This time I Removed the 7400 series chips that are in the affected area so I can also clean the circuit board below the chips.
After removing the chips I still see some corrosion, so I cleaned it with a toothbrush.
When I finished cleaning, I placed some sockets and placed some new chips back.
When done with the chips, I pull the Gary from her socket and start removing the old corroded socket.
When removed, I again clean the circuit board with a toothbrush and place a new socket.
I Didn’t had a 44pin socket so I used a 40 pin socket and cut a part of another socket for the remaining pins.
After reseating the Gary I reassembled the Amiga and powered her up.
The 2.o Kickstart welcome screen is shown on my TV ( in color 🙂 )
While doing some more testing, I found out that I couldn’t type “dir”.
the R key did not respond. after a quick test I found that the keyboard was not responding on two columns, the column with the R and the column with the T key.
So next mission for this Amiga is to check the keyboard and repair/replace it.
