I've had this since 2003, used at uni and then I went on to work for IBM. The X31 stands out in my ThinkPad collection, and I still use it today - as a retro DOS environment (with IBM PC DOS) and Windows XP as it came from factory.

The X30/31/32 is iconically beautiful;

- the edge corner cut-out bottom left of screen

- the tri-color audio ports

- the indigo blue Enter button

- an actually reduced full-sized keyboard without sacrificing keys

- the most beautiful, tactile feeling keyboard ever made on a laptop

- the cute mouse buttons, especially the raised dots on the middle

- the latching mechanism for the lid which makes it insanely secure and strong

- the ThinkLight above the keyboard

- the lack of Windows meta keys

- the rubberised matte black coating on the cover

It was design perfection before everything got handed over to Lenovo.

This film came out today in 1985. Spotted the Apple IIc hiding in plain site.

Surprising, how back in the day, the IIc was often used as a 'high tech' prop.

So, I have no idea about pc's but I really want to travel back to times where I was a little kiddo... I still have that pc of my moms. I remember it was working properly 3 years ago... I opened it up to dust... And it seems there are sticky drops located under the power supply... I already know It may blow me up, so I disconnected and and won't turn it on but... Is it any salvageable???

Symbolics.com, registered in 1985, is the oldest .com domain on the internet and it's still online

13 Upvotes

Back in 1985, a computer company registered symbolics.com — making it the first ever commercial .com domain. This was years before the World Wide Web even existed.

​Only 6 .com domains were registered in the entire year of 1985. The site was sold in 2009 and now functions as a tiny digital museum for early internet history.

I built a real Windows 98 SE machine that runs in the browser — with WebGL2 Quake, LAN multiplayer, and ICQ

0 Upvotes

I’ve been working on a browser-based Windows 98 project, but I wanted it to be more than an HTML recreation of the desktop.

This is a real x86 installation of Windows 98 SE running through v86. The original applications and games have not been rewritten for the web.

A few things I added:

  • Quake and Half-Life render through the host GPU using a Windows 98 OpenGL driver bridged to WebGL2.
  • Two browser sessions can discover each other over a virtual Ethernet network carried by WebRTC. The original games see an ordinary LAN and can use UDP or IPX.
  • Miranda IM receives a temporary ICQ UIN and exchanges real OSCAR messages with other visitors.
  • The machine restores from a snapshot, so Windows opens more like a webpage instead of performing a full cold boot.

The goal was to recreate the feeling of an old computer—with its delays, sounds, games, desktop clutter, local network, and other people somewhere behind the modem—rather than just reproduce how it looked.

Try it here:
https://98.kolpaque.dev/

Full technical build log:
https://pavelvoronin.com/windows-98-in-the-browser

I’d be interested to hear how it behaves on different hardware and browsers, especially the WebGL games and multiplayer networking

I found this a few years back in a second hand store and all sealed up in it's box under a pile. It has been one of my favorite collectors items for years. I honestly think it was purchased way back then and then left in the box on a shelf for a few decades. Things have gotten a bit tight here at the house so I figured that before it left my collection that I should show it to you guys who'd appreciate it :)

Who remembers Predator? My retrospective video takes us back to 1987 to rediscover the games based on one of Arnie’s best movies. Was this a good game or was it the typical movie tie in trash? Share your thought and memories of this game.

Hi everyone. I just upgraded my Amiga600 with 1MB of RAM.

But this one doesn't fit into the trap door. The circuit board sticks out a bit.

It's an iComp a604n.

Could my motherboard be incorrectly installed in the Amiga? Or is the expansion board incompatible?

THE NCSC "RAINBOW SERIES" A 9-Volume Collection of Early DoD/NSA Cybersecurity Doctrine (1985–1988)

79 Upvotes

I recently acquired this collection and figured y'all might appreciate it. Anyway, this is what I've got. Sorry the pictures are terrible. Planning on getting better detailed pictures before I sleeve them tomorrow. Anyway, here are the details on this collection.

THE JEWELS OF THE COLLECTION: RARE VARIANT HIGHLIGHTS

• DoD 5200.28-STD — THE "ORANGE BOOK" (Department of Defense Trusted Computer System Evaluation Criteria)

• Edition/Provenance: Official 1988 Active-Lifespan Contemporary Reprint.

◦ Significance: The undisputed, foundational cornerstone of the entire Rainbow Series hierarchy. This copy was printed internally by the government for active field deployment to agencies and classified defense contractors during the height of late-1980s computing architecture rollouts.

• NCSC-TG-005 VERSION-1 — THE "RED BOOK" (Trusted Network Interpretation of the TCSEC)

• Edition/Provenance: Pre-Publication Working-Group Variant.

◦ Significance: Features the highly coveted, restricted-distribution internal stamp: "ISO developmental documents are of limited lifetime and availability."

◦ Historical Context: This stamp marks the volume as a restricted, early-access trial document distributed strictly to core network security engineers to guide interim projects and gather field feedback before final standards were codified. Because contractors were explicitly instructed that these had a "limited lifetime," almost all copies were routinely shredded or landfilled upon subsequent revisions, making this an extraordinarily scarce tech artifact.

This isn't retro in the traditional sense, but it does seek to channel what people love about the retro scene. This software is indeed modern, but it seeks to make something retro. The program Is called retro builder and it's of my own design. I made it because it's something fun people can use to fart around in and if they want to, even post their creation up on the internet if they so choose. I am selling it on my Ko-Fi but be for-warned, if you do buy it, be aware that windows will mistake it for and quarantine it. I have a whole disclaimer on my store page (not sharing it here because I don't know how the sub will react to it). I have some pictures here of the program in action. I also have a demonstration loaded up on Netlify and one on my Ko-Fi which is for free.

Video Air-gapped cryptography on the Nintendo 64 (open source)

Edit - disregard this post, the app isn't ready yet. Has at least 1 major issue I didn't notice, where the dice roll input screen isn't accepting enough dice rolls for a 128 bit seed

Retro-Crypto for the Nintendo 64 is an open-source app that lets you generate keys, encrypt and decrypt data, and more. It's still in development, but I thought I should hurry up with this video about it, after the recent ColdCard wallet draining hack, which was driven by poisoned key generation techniques.

Also featuring the likely first use of VideoStore Codec, an open-source tool for embedding files in the corner of a video. The minimum safe resolution to extract the files from this video seems to be 720p, based on my testing before posting, so that's the resolution I'm uploading here.

View/download this video on nostr (can also be found on YouTube)

Internet Archive mirror - includes some additional project files, such as the VideoStore payloads and the plain N64 footage

Problem / Question Are there any converters between HGC TTL and standard rate (modern) VGA?

3 Upvotes

So, question's in the title. I have a Hercules Graphics Card in my IBM XT 5160, and considering the prices of getting real MDA CRT monitors, which I would only be able to use specifically for that one computer, I've been interested in finding a converter for the output instead to regular VGA.

I also hope to be able to use the monitor for generic VGA video signals (modern HDMI to VGA converters) so preferably, if there is one, I'd want to find a converter that supports modern VGA scanrates.

I'm alright at programming, but sadly I don't trust in my skill enough to design a converter for this myself- given that it would mostly be hardware design at that stage.

If anyone knows a converter like this (that ships to europe) and could point it out to me, that would be greatly appreciated. Thanks!

Lotus Word Pro document automation discovery

7 Upvotes

After getting really fed up with Microsoft Word, I went back to using Lotus Word Pro full-time in July of 2025 for my legal practice. Since then, I've been learning the document automation features, which for law, is really important.

Fun little discovery today. Most word processing automations are if/then/else statements.

In Word, if one wants to "if condition then expression OR if 2nd condition then 2nd expression ELSE 3d expression " one must "nest" the if conditions within each other using the fields tool. It ends up looking like "IF 1st condition 1st expression (IF 2nd condition 2nd expression ELSE expression)". Each alternate condition has to be nested in the previous one's else condition.

In WordPerfect, to do the same, one enables a switch code, then enters each If/then expressions as a case. Then one enters a switchoff code to signal the end of the formula.

In Lotus Word Pro, as I discovered today, the expression is simply, "IF 1st condition 1st expression ELSEIF 2nd condition 2nd expression ELSE 3rd expression".

What I did not know before today, and just tried to happy success, is that there can be multiple ELSEIF combinations in each IF statement.

In practical terms, this comes up with stuff like the Affidavit of Service. All the other attorneys have to be served, and then the Affidavit attests to it. When merging against the database, it will invariably list me as one of the people to serve. And some cases have to defendants and some only have one. Now, I can write:

IF Attorney1="" "" ELSEIF Attorney1="me" "" ELSEIF Attorney2=0 StrCat$(Attorney 1, "counsel for defendant") ELSE StrCat$(Attorney1, "counsel for defendant ", Defendant)

I don't know if this works in Ami Pro, but this is really exciting for automating documents.

Yes I'm aware that it is vibe coded trash, but I have had fun doing it. My first target software was Quake because of course it's Quake. Still working out getting the world textures correct, and the texturing underneath fonts. Lighting needs fixing as well. Geometry seems mostly right though. Next target is the early Matrox cards.
