In this post i’m going to show you how to make it technical posible to have 2 drives (Gotek & disk drive) inside a Amiga 500, 600 or 1200. The internal FDD header (CN11) does not have all the needed signals to add 2 drives to this header, it’s imposible to have a DF0 & […]

Amiga 600 low right audio signal
Today on the bench, an Amiga 600 that had a recap but the right audio signal is not as loud as the left channel. The problem Left signal has voltage level of 1,32V, right 680mV. So opamp (LF347) is bad or something in the signal path, but i’m going to check the signal path first. […]
Amiga 600 in reboot loop
Amiga 600 which was constantly rebooting. I got this machine as a repair, someone before me tried to do a recap to the machine.. After that it was not working anymore. First thing I tried was to replace the 555 Timer (U14) and the C612 Capacitor, because this is common problem on an Amiga 600. […]
Amiga 600 IDE port replacement
Amiga 600 with HD boot problems. This board had a recap because it leaked from the caps. Some electrolyte leaked under the IDE header and a corroded the pins. Sometimes after reseating the IDE cable it booted, but mostly it didn’t boot. I removed the IDE header cleaned the mess underneath it and placed a […]
A600 – no boot – capacitor acting like resistor
Amiga 600 which didn’t boot. Did some measurements on the 555 timer ic’s, and I saw the trigger threshold was too low, 1,2 Volt. It should be some where around 2,4V. So I guessed the problem should be R611 or C611. Removed both, R611 was good, however C611 was acting like resistor of around 45K […]
