Early Vid: Trying to Fix Sun Microsystems Equipment
Added 2023-11-30 16:21:51 +0000 UTCSome attempts at fixing a SunPCI III Pro, a Sun Ray 270, and a Sun Ray 2FS. We'll have some successes... and some failures.
Video should go live on the channel tomorrow afternoon!

2023-11-30 21:41:55 +0000 UTCThanks for the tips โย 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.

2023-11-30 21:15:32 +0000 UTCGreat 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 didnโt change anything. Itโs 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 Iโd 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 Iโve 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) Iโd 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 canโt say I noticed it growing but I had seen it before and thought โI canโt wait to see what project that will be forโ.
