The Bell System has a special place in my heart, soul and mind 🙂. Also, overall, I've been really enjoying your work since I found you a few weeks ago! Love all the Big Business machines you play with. Keep it up Brother!

I thought that stack looked taller this video. LOL

Thanks for the tips — I'm probably going to use this as an excuse to get an ESR meter and a desoldering station haha. I did actually test an external monitor on the 270, no luck. I should've included that in the video. For the laptop I didn't test it first, so you're right, it could be bad RAM or, very likely, I didn't seat a ribbon cable properly. I'm going to dive into that one briefly over the weekend because I *suspect* it'll be a quick fix.

Great video as always. So neat to see inside this (mostly) forgotten hardware. Sun PCI 3 Pro: I agree on it being a capacitor issue since it suddenly stopped working and you didn’t change anything. It’s also hard for me to believe that you cooked that CPU since all it did was post. For checking caps on this and future projects I’d recommend the $120 Atlas ESR70. Could help isolate the issue and save you some time rather than going for the full cap replacement Hail Mary. I found that more often than not it is only one type/value of cap that goes bad. Compaq 2100: Did you test if it was working before you took it apart? Could be wrong type of RAM? Besides that I think I’ve had a similar issue to that in the past when I had a ribbon cable plugged into the wrong place (trackpad ribbon plugged into optional fingerprint scanner slot or something like that) I’d remove ribbon cables until it boots, then plug them back in one at a time. Sunray 270: Have you tried hooking up an external monitor to it? That will at least determine if the issue is the board, or the connection to the monitor. Love the Linksys tower, I can’t say I noticed it growing but I had seen it before and thought “I can’t wait to see what project that will be for”.
