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 al…

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.

I thought I’d power up and inventory my systems that don’t have CPUs made by Intel/AMD/Cyrix, but are x86 compatible. I do have a few! Let’s have a quick look at them in a 🧵 here!
Let’s start with the system on the far left, the tower. It happens to be an ITX Llama system, built around the Vortex86EX CPU. It’s similar in performance to a 486 or Pentium system. I did make a custom BIOS build to play the Nokia tune 😂
Oh, I should give some specs. 128MB RAM, ATI Rage Pro 128 AGP card, 120 GB SD card for storage, Crystal audio, and an RDC Ethernet card as you will see from my Windows screenshot here. This is a quirky system.. a bit buggy... and I HAD to use QEMM for memory management

I just made a 10 cent improvement to this Compaq LTE Elite 4/75 laptop. Anyone want to guess what it is? Let’s talk about it in a brief 🧵 here!
Did you make your guess? Yep! It was the screen latches! For 10 cents, my local library’s makerspace printed these for me today!
Here are the prints. Apparently they have a TA26 and a Prusa printer. The lady at the makerspace said "use the Prusa ones!" And so I did!

It’s been a little while since we have had the Dell Precision 220 Workstation on the desk. I’ve had several requests to install Haiku on this Dual Pentium III beast. Let’s get it done! Time for a 🧵
So, first, this PC already has a lot of OSes! We’ll create a 4GB BeOS partition to install Haiku, and add it to the list of OSes to boot!
I downloaded the latest stable version, which appears to be R1/beta5, and burned it to a DVD!
