When pushed with a suitable tool (say, a #1 or #2 Phillips screwdriver), it clicks in and clicks out very nicely. However, still no joy. It stays powered up, and a voltmeter shows nice voltages on the +5, +12, and -12 lines, but nothing happens, in particular no sound from the speaker. The CPU gets warm enough to detect by touch (implying that it's getting clock), but that's all it seems willing to do. Should I expect the startup chime even with no monitor connected? If not, what pins should I jump to make it think there's a monitor connected? The DA15<->DE15 adapter I found (the one I think I wired up myself) connects DA15 DE15 1 ------------- 6 2 ------------- 1 3 NC 4 NC 5 ------------- 2 6 ------------- 7 7 -----+ 8 NC | 9 -----|------- 3 10 -----+ 11 ------------- 10 12 ------------- 14 13 ------------- 8 14 ------------- 5 15 ------------- 13 Is that jumper between pins 7 and 10 suitable? It still didn't chime with this adapter connected but nothing plugged into the DE15. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
