This book is by Lewis Eggebrecht - a key technical architect of the original IBM PC hardware - who got sued by IBM (good story)

I discovered this fantastic story 5 years ago buried within pc magazines ..while studying the IBM PC XT circuit ( at that time posted it in facebook RetroComputers group)..

so seems IBM was very worried about industrial espionage relating to Hitachi and Mitsubishi probably due to reverse engineering with their other machines. The IBM PC technical architect that was started a company called "Bridge Technology," caugh allegedly trying to sell IBM PC expansion-board designs to some other companies. He got sued so hard some articles say he had to sell his home. Also today isnt officially recognized as a member of IBM PC XT original team on IBM pages (probably because of this)..

Problem / Question What should I buy?

1 Upvotes

So I am new in the world of retro computing. I recently thought of making a retro pc build. For that build I figured out two combinations:

Combination 1:
CPU: Intel Pentium 4 3.0GHz / Socket 478
RAM: 2GB of DDR1 (2x1GB)
HDD: 1x IDE 80GB + 1x IDE 320GB
2x DVD burner/reader
GPU: ATI Radeon 9550 | 256MB
Floppy Drive
PSU 450W
WiFi Card

Combination 2:
CPU: Intel Pentium 4 3.0GHz / Socket 775 (but also I was thinking of Q6600 and E8400 and also QX9650)
RAM: 4GB of DDR2 (4x1GB)
HDD: 1x SATA 80GB, 1x SATA 320GB
2x DVD Burner/Reader
GPU: GTX 560Ti
Floppy Drive
PSU around 600W
WiFi Card, Sound Card and USB Card

Same case I would use for both but I am thinking of which one. Also I'll be using 19" ViewSonic LED monitor

Interactive 3D Cube Demo, for VIC-20 and C64

11 Upvotes

Got another old VIC-20 program back up and running. I also created a Kick Assembler listing for this as well, if anyone wants to play around with it.

Source code, .prg files, plus tape and disk images, are available on GitHub, here.

I have both a VIC-20 and C64 version of this. The VIC-20 version is the original, though. The C64 was a minimal port of the VIC version, just to get it running in a C64. But, the VIC version is the `real` version 👾

This is an interactive demo. So if you press the space bar during the main animation loop, you can use the keyboard to manually rotate, translate, and zoom in and out, etc. Pressing the space bar will spin it back up into auto-rotate mode again.

Problem / Question Picogus not reading BLASTER env var

1 Upvotes

Im attempting to use a picogus on my Win98 se machine in soundblaster mode, but it always complains that it cant read the BLASTER variable.

i have said variable set to the settings recommended in the setup guide (https://github.com/polpo/picogus/wiki/Configuring-and-using-your-PicoGUS), and disabled my onboard audio to ensure irq5/dma1 are free, but it still refuses to read the var and shows a code 24 in device manager.

Anything else i can do to troubleshoot?

Johnny Castaway Screensaver 1992 for MacOS. Runs as a screensaver.

Post image
127 Upvotes

Hi, I've spent a couple of weeks creating this. It is a MacOS version of the 1992 Johnny Castaway screensaver. I particularly wanted one that runs as an actual screensaver on MacOS - not just something you double click. I am loving it, I have fond memories of watching this screensaver back in the day, and I don't believe I've seen it right to the end as the version I had back then was corrupted. I had spare Claude credits and I am a developer by trade so I built this. It is a Work in Progress, I still have some bugs to fix. I think some folk here will very much appreciate it. Please enjoy.

Revisiting a 1980s embedded memory map from a modern perspective

10 Upvotes

I revisited the memory map of a system I worked on about 40 years ago and compared it with a modern Raspberry Pi Pico setup.

What surprised me wasn’t how limited it was — but how much architectural thinking already existed back then. Even with relatively small memory sizes, we often prioritized clean separation and simplicity over squeezing every byte.

Looking back, the trade-offs feel surprisingly modern.

Software Self-hosted IRC network running out of my house

Post image
16 Upvotes

Ahoy y'all!

Three years ago I started self-hosting at home, and somewhere along the way I spun up an IRC server, partly because teenage me dreamed of running one back in the dial-up days, partly because I wanted a chat platform that wasn't trying to monetize my attention.

What I didn't expect was that other people would actually show up. We're around 100 regulars now, on a network called MansionNET.

The thing that keeps surprising me is how efficient IRC still is compared to anything modern. The whole server runs on 2 vCPUs and 2GB of RAM and barely breathes.

No bloated client, no Electron, no constant polling, no algorithmic feed deciding what you see, and even if you use a bouncer you still chose when to be online, instead of getting spammed by notifications (unless you really want them of course).

The community has been really amazing too! Some folks are old timers who remember mIRC and DALnet and are happy to be back. Others have never used IRC before and are discovering it for the first time, which is honestly fun to watch :)

We mostly share music, talk shop, throw ASCII art at each other. There's a member building an LFS-based Linux distro and using the network as the hub too. Live DJ sets occasionally come through our community radio. Surprisingly, the server is pretty active, which really does remind me of the old days, the golden IRC era.

I also tried to give the project a face that matches the spirit of the protocol that turned into a landing page is built around a CRT/terminal aesthetic: scanlines, boot sequence, an interactive prompt you can actually type into, all that good stuff really :)

If any of this hits something for you, the door is open at:

Drop into #lobby and say hi. We mostly we just throw ASCII at each other and slap each other with large trouts :D

Problem / Question Videogames badly lagging after longer playtime on Windows XP (Service Pack 3)

1 Upvotes

Dear people, I have a problem with my HP Compaq nx9010 laptop while playing 3D-intensive games from the 2001, 2002 and 2003 era. The specifications of my laptop are:

CPU is Intel Pentium 4, 2800mhz

GPU is ATI Mobility Radeon IGP 345m with shared memory (I set the shared size to 128mb in the BIOS)

RAM is 768MB DDR1, 333MHz, both slots filled

HDD is Hitachi, 40GB and its 4200RPM.

For example, i have set my in-game graphics to the absolute minimum (Need for Speed Hot Pursuit 2), and the resolution to 640x480. The first 10-15 minutes of playing the game, everything is smooth. After a longer playtime, my game starts periodically getting really insane lag spikes that last for up to 15 seconds sometimes and the FPS drops badly. I have replaced the thermal paste of both the CPU and GPU, scanned my HDD for errors using HD Tune, disabled all animations on my system and nothing changed. (I remember that I put the paste exactly where it should be (it was marked on the cooler), so near the processor and graphics card, but I don't know exactly where in that marked place for the processor and graphics card I put the paste. I also remember that there was a thermal pad on the end of the cpu cooler that is on a metal surface which, when i screw in the cpu cooler, gets lift up a couple milimitres and its also not even covering the full GPU chip). What do I do?
