Checking out this Quantex computer that I picked in LGR Thrifts Episode 47. It's a pretty neat little system with a Cyrix 486DX2-66 and a Socket 3 motherboard with PCI slots! Got a few things to tweak and upgrade but it's pretty solid as-is.

So it turns out this is a rather infamous variant of a board known as the M919! While doing some testing off camera I was wondering why I couldn't detect the on-board 256K cache through testing software, and welp. Seems the company PC Chips was doing some shady crap back in the day with fake/non-working cache chips. Not only that, but apparently there's some kind of lockout where you can't use anything but their proprietary 256K COASt module. Amazing.

Luckily, modern reproductions of the M919 256K cache module exists and I ordered one. Here's a follow-up! https://youtu.be/mZnS-whVuDI

When the BIOS has a more advanced look than the actual operating system...

This board has the well know fake-cache chips. Seems to be the famous M919 from PC Chips!

This was the first computer I ever used. I remember my father placing me and my twin in front of it and saying "this is the future, and you need to learn how this works."

This is the computer that taught me how to read, how to spell, and how to do math.

Jill of the Jungle sounded more like a portal to hell opened than Doom did lmao

Quantex always had the top performance specs in computer magazines, back when
performance was doubling every month.

Dude. I almost had a heart attack when I saw this! I had a quantex 486dx2 50mhz that had a case exactly like this! I've been looking for years on the internet just for a PICTURE of my beloved machine from hs and never found one until literally just know. I'm so happy 😊 awesome channel, I've had a shitty week but this made my day!

Would love to see if the Pentium Overdrive would make a difference here with the Better Motherboard compared to the 486 overdrive.

Haha, I also remember pissing off my parents before we got a dedicated sound card. King Quest V in particular and all those beep-y songs must have been very annoying when you’re trying to sleep.

I have nothing to say of value, but thank you for this and all your other vids. I was in such an awful mood, but watching this helped turn my mind back around. Thanks LGR.
