YouTube video by Al's Retro Geek Lab Slowing down my CPU made the XT run FASTER (using a programmable oscillator!)

I slowed down my clock speed in the hope that it would increase the CPU speed of my XT. I used a programmable oscillator too. Here's what happened!

Just casually getting some time with my favourite loafer in a Leisure Suit. On my XT, of course. 😁

If you're a fan of the movie Sneakers, the late Robert Redford (RIP) or just geeky things, you can ssh into sneakers@ansi.rya.nc and watch the movie in glorious 24-bit colour ANSI :) Enjoy!

The XT that became a high end 486 without a motherboard swap now runs DooM at 20 fps!

Upgrade and XT to a 486? Surely that's impossible?!

I just spent far too much money on this thing. The Intel Inboard was a way to upgrade your PC or XT to have a 386 CPU. It gave you the opportunity to run 32-bit software despite having an 8-bit bus. I want to run extended memory apps, this is /apparently/ the only way!

This VHS tape sized subnotebook from 1997 was really innovative for its time; but was it any good? Let's look at the Toshiba Libretto 100CT! youtu.be/uAlhPwcHbdo?...

And since I'm new here, I'll introduce myself to #retrocomputing too, with my latest YouTube video, which covers Windows 3.0 on a real 286 PC and an in-place upgrade to Windows 3.1
