Entro441 Posted August 22, 2021 Share Posted August 22, 2021 I have recently picked up this iasis ia-7301 computer from 1976. It runs on a amd 8080 cpu. It had all the original instructions, and the computer looked to be in good shape. It did not come with a power supply. I tried to connect the machine to a power supply based on it's instructions, but it doesn't turn on. Using my power supply, I found that there was an issue with the 5v. I checked the connection at the terminal, and they are all good, and when i power off the power supply, there's a brief flash of life, so the problem is to do with the board. I found a schematic, but its really bad due to it being in black and white, but maybe someone can figure it out. Any suggestions? Quote Link to comment Share on other sites More sharing options...
Entro441 Posted August 23, 2021 Author Share Posted August 23, 2021 Update: the issue was that the cpu wasn't seated properly. The machine now works. 1 Quote Link to comment Share on other sites More sharing options...
