Hi all - a newbie here with a problem
I got a vintage (the board is dated 1988) GPIB-232CV (not -A) 64K adapter that I wanted to use to connect my HP 7475A plotter to a modern PC. I connected power to the adapter today to test it - it came on with all LEDs fully lit up. After around 2-3s I smelled smoke, so I disconnected quickly.
I openned the case and it seems the board is in a good condition, but one of the capacitor has blown (seen in the photo in lower right - C40). I am hoping to fix it (can't afford a new adapter on a student budget), but it seems I can't find a service manual for this particular model (the model doesn't even show on NI website). I am hoping someone has a copy of a service manual or know what capacitor was at C40 so I can replace it.
I suspect the core problem was a faulty power supply, so I am hoping to get a modern PSU connected after I deal with the capacitors. However, maybe all the LEDs being lit up on power on is a known code that points to some other issue.
Any help would be greatly appriciated.
