Heyo folks,

https://youtu.be/YI3yeY2sOo4

Al's Geek Lab delivers you -- my IBM 5160, complete with original 256K motherboard still in play, delivers you a slice of DooM running at ~20FPS.

Yes, it is running with an upgrade card - an Intel Inboard/386 PC
Yes, I rodded the hell out of that too, with a ParrotyError 4MB ram expansion piggyback board and an IODATA PK486 Blue Lightning 3 (IBM/Cyrix) CPU which clocks in at 96MHz!

It's wild!

Lettuce know what you think!

Cheers,
Al

Really cool! Love the vids! And I recognize the sound of that IBM power switch from when I used to have a PC/XT/AT... =)

Best regards

Amazing to watch! I see sleeper builds with modern motherboards in old hardware, but seeing an upgraded IBM PC motherboard running is pretty
amazing. I don't recall seeing the keyboard, but typing on one of those
XT keyboards with the Fkeys on the left would be a walk down memory
lane.

Dude - that computer is so sick... I've watched you morph it into the beast it is over several YT videos!!!! So cool.

Thats so cool, I wonder how much further you can push it!

Is the processor on the piggyback board socketed or not? If it is I wonder what you could replace it with......

Lettuce know what you think!

You've turned that 5160 in a real Rocket ;)

Also I wonder what performance would be like using a super XT motherboard that runs at a higher clock speed than the XT? Bumping the ISA bus speed up to 8 or 10Mhz would surely speed things up quite a bit!
