I know I’m not even close to finishing my restoration of a #MacClassic, but is it too early to be thinking about #DOScember ?

I may have “accidentally” purchased an #IBM5150 for some holiday cheer.

I bought upgrades new and old for my IBM XT, but there wasn’t enough #DOScember to take a look at them then… so I thought what better time to take a look at them than tonight, live starting at 9PM EST! youtube.com/live/1JQnjEFHxGw?s

Needs cleaning up (pencil marks), but looks pretty decent. I just need to add a floppy activity LED light and small hole for the speaker (floppy drive sounds). Then it's mounting it all inside. Not too far off now, has turned into 😆

In a classic "it's me" move, now that it's January (after the deadline), I finally managed to boot the 486DLC into DOS.

Also wrote my first XT-IDE ROM in the process, not because it's technically needed, but because I wanted auto-detection, because I was too lazy to figure out the "geometry" of the 256MB DoM I use... 🤪

Also managed to get online using mTCP (IRC log feat. @ratman), and figured out this thing is pretty slow for a 486DLC. Oh, well... 🤷‍♂️

The 486DLC motherboard laid on the desk, with 3 cards inserted, a VGA, an Ethernet and a multi I/O card. The system is booted into PC-DOS 2000 (a.k.a. 7.0 Revision 1). The screen shows the boot messages, but also the XT IDE ROM, seated on the Ethernet card, detecting the DoM hooked on the IDE controller.The 486DLC running DOS Navigator 1.51, using a custom Norton Commander-alike color scheme.The 486DLC is connected to the internet, running IRCjr from the mTCP package. The IRC chat on the screen is in Hungarian, and talks about the adventures getting the system running and online.The 486DLC running "3DBench", a known benchmarking program for 486-era systems. It achieves 18.8 fps, which is not great, but not terrible for such a system.

Last minute entry, if fiddling with BIOS stuff counts... A while ago I bought this Soyo 386DX mainboard with a 486DLC + FPU in it from evilBay, with the intent of reproducing one of the quirky and weird setups of my youth. But that board had Mr. BIOS in it, while this thing came with AMI BIOS.

So I bought a handful of 27C512 EPROMs, burned a matching Mr. BIOS image thanks to the preservation efforts of people on Vogons.org, a quick chip swap and here we go. 😍

The sun is about to set on #DOScember and 2024, but hopefully my Sun will let me run DOS applications into 2025 via the SunPCi card… that is, if it works - it could be my final eBay regret of 2024. Let’s find out live this evening starting at 6PM EST! youtube.com/live/DcIa4CoPl90?s

A big thank you to RetroTechChris (on X) for sending these FPM RAM sticks all the way from the USA, for my 486 build. Very much appreciated, I can't wait to test them out once my build is done 🙏

Hey #RetroComputing fediverse,

What are #Scheme Lisps compatible with #FreeDOS or #MSDOS ?

So far I found: PC Scheme, EUscheme, Gambit, SCM and KiloLisp.

Thank you

NEW VIDEO : This #Doscember there are questions to answer. Is Microsoft Flight Sim the oldest gaming series still supported? What is the future of Multimedia before any computer can do multiple media? How do you do an interactive movie that is neither interactive nor a movie? youtu.be/uyw92MaY0kg

3 planes fly across the desert. They are computer graphics but impressive ones as they are from Flight Simulator 2024. The text asks if it's the oldest video game series.

What’s madness? Buying high (and low) value motherboards on eBay and thinking I can repair them, that’s what. Let’s take a look at a few DOS-compatible boards for #DOScember to see if I can repair them, live tonight starting at 6PM EST! youtube.com/live/JD_oHm54rrE?s

I like to install weird operating systems so I made a video about it.

Happy Friday and Merry Christmas to everyone, I've officially finished work for a two week break. What more could you want at this time of year in than to build a dream machine from your childhood, my second PC was a 486 desktop and I'm going to build one from scratch.
