This is fascinating, the Computer Devices' DOT, the a portable that was the first computer to ship with Sony 3.5-inch disk drives and it had a *widescreen* CRT display (which supported 132x25 textmode!).
And the video ... has some surprises...
Well worth a watch.

So if you ever wondered how OpenBSD 7.7 (most recent one at the time of writing) works on 23-year old PC, I have recorded a boot process.
CPU: AMD Athlon XP 2000+ (single-core 1.6 Ghz) from 2002. i386, of course
RAM: 512 Mb DDR2
HDD: Some Western Digital 80Gb hard drive from ~2004
Fresh OpenBSD installation without any tweaks and tuning boots in 88 seconds.
There's definitely a room for improvement such as turning off libraries reordering (we should't worry about security too much on such machine). Less then a minute is easily possible.
But still, results are amazing, I think. It's a 23-year old PC! And it runs the most recent OS without any trouble. Try to do that with Windows 11 or any mainstream Linux distro.
Also, #FVWM is pretty snappy and works just fine.
This is astonishingly impressive: A2Stream
"A2Stream simultaneously receives an .a2stream file from any HTTP server and plays it through the stock Apple II speaker circuit using pulse-width modulation at 22050Hz sample rate with ~5.17 bit resolution."
Demo video with direct line-in - sounds amazing:
What was the most popular RAM size of #retrocomputers?
According my pseudo-random sampling of 119 machines, it's 64K.

Studio Changes Looking Good! Cables off floor. Gear mounted off-floor to get rid of stands. Everything wired for doing Live streams. Bonus: My guitar & Korg have room in the studio now.

Its one big acronym salad. 
There is no reason to believe that the original title of this game was "Uncle Clive" or that the cover depicts an angry, jealous Sir Clive Sinclair smashing a BBC Microcomputer with his fist. Any resemblance is purely coincidental.

Amiga CD32 discs have interesting layout: first - data track, then - audio tracks, like this (captured with cdrdao):

Wondering is it always so? 
I only have several 
game and demo discs to explore 
Someone is selling the following #retrocomputers for $1,000 I kind of want them, but I prefer emulation these days.
1 486 DX multi hard drives
1 Pentium 66 mhz
1 dual processor 166 mhz
1 AMD 350 mhz running OS/2
Or best offer
1 Sony Flat screen monitor
3.5 disks also 5.25 disks and CDs
I had performance problems in #Doom over #IPX, that turned out to be because one of my nics was running at 10 half duplex.
So I replaced it with a PCI nic. But it wasn't getting an IRQ at all. So I had to move it to a different slot which was directly next to the AGP. So now there's capton tape on the back of the NIC so it doesn't short out against the VGA heatsink.
Aren't #retrocomputers just the best? 
This opens right in front of my apartment!
Demoscene, retro computers and they even shows 2600 magazine :)
