Waiting for parts for another project, I decided to give my DEC Digital VT180 Robin a look for the first time after acquiring it years ago. This is a CP/M personal computer based on the VT100 as a base. Looks like the CRT is messed up. Not an unexpected project :( #retrocomputing #vintagecomputer

I am sort of happy to have found the issue! Unfortunately, it's the power supply so now I need to troubleshoot that. I swapped in a power supply from my VT100 to test and it worked fine.

Well, turns out one of these 590uF 200v blue caps is completely open in the DEC VT100 model H7831 power supply. I've ordered a set of two to replace both. It was a last resort check as I have never seen these large caps go bad. Let's hope it's only that. #retrocomputing #vintagecomputer
