This is several kilobucks worth of hardware that was misapplied to create a special filter that…. nothing would pass. See if you can spot the issue!
Our IT director dropped a non working Wyse serial terminal on my bench. I don’t think he expected me to tear it open and try to fix it, I think it has an open diode or bad cap in the +5v supply. It’s gonna be the serial console for a Linux machine if I can get it glowing.
This has been a elliptically polarized shitpost.
