On another note is my IMSAI 80/30. When turned on the screen fills from the bottom up with alternating vertical lines and triangles. Any thoughts?
This is a good sign. It indicates the following: 1) The display circuitry is successfully translating memory contents into a video signal and the video display itself is functional. 2) The CPU is operating, at least to the level that memory contents are being modified in a systematic way. Since you have skipped a number of steps that I would have recommended to verify that the main power supply is "good", I would recommend that you reseat (gently lift and reinsert) each of the cards in the unit and see if that alters the behavior. Before you reseat the cards, turn the unit off, leave it for three or four minutes, then unplug it from the wall and leave it for another three or four minutes. Bill S.
