ScuzzBlog: Diaries August 2017 Entry 19th August 2017: Post: 2 Back to the Tower [ diary entry ] The tower has been a touch flaky to say the least and has a habit of rebooting when I am not looking. I decided to go in deep this time. First up I removed the monitor port and allowed the connector to lay loose as the fitting to the A1200 was not very sturdy. Next I swapped out the buffered interface which didn't improve matters so I stayed with the old. I then again worked all the connectors making sure that they were all well seated. And then finally I swapped out the motherboard. A little drastic but hey. Simple job of swapping a base from an Escom era machine. That felt better but I was still not certain. I mucked around a little more seeing if I could get the machine to reboot. I just sensed that when I stand the computer back up, in no time it will fall over again. I was rebuilding the standard cased A1200 from the motherboard and decided I never really checked the keyboard. I fired up the shell on the tower and discovered the right side of the keyboard was not functioning. I swapped out the motherboard to another and checked all was working. The computer felt better. Dunno why. I stood the baseboard of the changed motherboard upright and discovered that it had already been in a tower. It had the tell-tale notches top and bottom. Powered up and the computer worked fine. Interestingly I did power up without the Blizzard to start with and she was slower than a slow thing with a very good reason for being very slow. Been running for over an hour now and seems OK. I am going to leave the monitor cable loose through the trapdoor as it makes it very much easier to lower the motherboard if there are future problems. I also tested the rebuilt 1200 from the removed motherboard and she works fine. The guy that had this board had cut a slot in the back so he could drag a ribbon through. The scandoubler flicker fix thingy has a male connector on it. The other I have has a female. I tempted to get a gender changer and use the 1200 with a PC monitor. Gives me another project. So two 1200s working this afternoon. Not bad I guess. Back to the 500 now. Much more fun. scuzz Decided to swap out the motherboard Monitor port is always loose so will leave unconnected and loose through trapdoor. Tried different buffered interface. Evidence that new motherboard had already been in a tower from evidence of slots in edge The power to the motherboard. Seriously. Until the computer is stable I will allow the monitor connector to run loose at base of machine for ease of removal should there be problems Problem keyboard swapped out I may change the battery on the Blizzard The essential ZIP drive for backing up Later motherboard from the Escom Era My travel box with essential goodies Reconnected the old motherboard to an Amiga 1200 case. I cannot have a computer not working For now I will leave the Scandoubler. There is a slot in the back of this case so I may run it out to a PC monitor. Just need a gender changer Amiga 1200 back together and powered up She is alive... !!!
