Yesterday, I talked about a few systems I had that were not Intel/AMD/Cyrix based. Well, here's another one: my Gateway 2000 tower has a UMC processor in it! I haven't powered it on in a hot minute, so let's talk about it briefly in a 🧵 here!

As we saw from the intro photo, this system has a UMC Green CPU US5-SUPER33 in it. And, indeed, it is super! It's almost as fast as a 486 DX2/50! These CPUs were subject to a legal dispute, and thus were not sold in the USA

On power up, we can see that this processor is detected as a U486SX by AMI BIOS. Not all motherboards supported this CPU. But my Shuttle-HOT-433 board does!

Back to the Gateway PC, it sure is tall! When not on the desk, it occupies this spot to the right of the desk. Things are looking a little empty! I also use a PS/2 keyboard at the desk, so I had to go hunting for an keyboard adapter. I found a few!

Well, anyway, that'll do for this show and tell session, hope you enjoyed it! I'm going to go and find my back brace and put this thing back in its cubby 😂. Thanks for following along.
