Merry Christmas from SDF.ORG and the Interim Computer Museum

Merry Christmas and Happy Holidays to all of you! Wishing you a holiday season filled with love, peace, and magical moments with family and friends! And some fun games of course! #prge #retrogaming

Great time to donate to support living computers, all up and working at the ICM! With membership you could access to these machines, so you can visit the museum in person or from the comfort of your home! icm.museum and your company may match your donations!

7 days to find 7 new members to get us to 400 for 2025! The PDP-8/e and PDP-12 are counting bits in the ACs for you. icm.museum #retrocomputing #vintagecomputing

thanks to @retrogamingexpo.bsky.social and @scott.hanselman.com we gained over 20 new members and sponsors since late October. Getting caught up on membership letters. #retrocomputing #vintagecomputing #community

Happy DEC 20 day! from icm.museum 2026 will be the year of 36bits #retrocomputing #vintagecomputing #ai

Happy DEC-20 day to all those cool cats all around the world. You know the ones.

Is this acceptable for #retrocomputing #vintagecomputing in 2026?

Artist and former Thinking Machines Product Designer Tamiko Thiel visited icm.museum to see the new Large Systems gallery which features the Connection Machine. Tamiko demonstrates the CM-2's "friend height" a suggestion that Danny Hillis wanted to realize. #supercomputing #hpc #vintagecomputing

Stopped by the Atlanta historical computing society’s holiday party in Lawrenceville! #retrocomputing #vintagecomputing #ahcs #georgia

Video games are not just about consoles but also about computers. Thanks to our awesome volunteers and the amazing ICM @sdforg.bsky.social , PRGE 2025 had a great collection of vintage home and business computers. Short video: youtu.be/bFVZpAOQk8k #prge #prge2025 #vintagecomputers #clippy #icm

Happy DEC-10 Day from icm.museum !! 2026 will be year of 36 bits! Come play on the two SC40s and XKL TOADs #vintagecomputing #retrocomputing

Make the internet quirky again. Pockets still exist and probably always will, but the flatlander to redpill ratio is very high. The internet isn’t television.

Did you ever see the Thinking Machines Connection Machine 2 at the Wing Luke Museum? youtu.be/g0v2Lgugh9c

Thanks to Josh Dersch who stopped by to clean an RK05 pack and drive on a PDP-8/e as well as get a QBone running on the 11/23

Three groups (2 from Portland) visited today and noted @scott.hanselman.com and #prge as their source of awareness. Thank you for the community support! icm.museum

Adrian covers the topic of MFM disk drives youtu.be/8LbFKV_pPAE?...

Writing my own disk drive cleaning program today because I don't like how other programs do it. (Mine uses a butterfly pattern, and only runs for 20 seconds, because that should be long enough to unjam any gunk from the heads.)

This AT&T demo diskette was discovered in a large box of unsorted floppies. The instructions are for running it on a 3B2 computer which we have running as “lcm3b2” and is remotely accessible. Would you like to know what is on this diskette? #retrocomputing #vintagecomputing #floppydisk #unix

Yummy. Dirty key soup.

Happy #chuckpeddleday ! This KIMSI will be at PaCommEx NW in June 2026 for the 50th anniversary celebration of the KIM-1

@bcantrill.bsky.social @ahl.bsky.social Hey guys! If possible I think you should have Stephen Jones from the Interim Computer Museum on the podcast. Stephen used to work at the LCM and is continuing its legacy with the ICM. He talked about it on a recent episode of @scott.hanselman.com‘s pod.

The KIMSI came out of Roseburg, OR. This one will be running by PaCommEx NW in June, 2026

I frequently have to change switch settings on my XT-IDE and 5150/5160(XT) motherboards, and I was sick of constantly having to go look up the tables to decode the switches. So here are a couple web-based tools to help out. github.com/misterblack1...

Boy am I happy to get this repaired and buttoned back up after buying it at VCF MidWest!

Open sourced Zork today opensource.microsoft.com/blog/2025/11... and ran it on a swarm of containers in the cloud 😂

It's official! #PicoIDE, the open source IDE/ATAPI drive emulator I've been working on for the better part of this year, will be launching at Crowd Supply! Go there to sign up for updates and to be notified when the campaign is live: www.crowdsupply.com/polpotronics...

The battery leakage damage (which I cleaned up in the photos) is almost cool looking. Luckily it usually stays relegated to the battery section, leaving the RAM expansion portion working.

oh no, prophet-5 dead

Today Timothy Elkund toggled in and ran Dean McDaniel’s KILL THE BIT on an Altair replica for the first time. icm.museum #altair #intel #program

Remember the Living Computing Museum? Then you should support and visit the Interim Computer Museum right near the Seattle Airport! Check out this special video I did with curator Stephen Jones and consider a matching donation - support the ICM! Please share! www.youtube.com/watch?v=EFkx...

The deep clunkyness of this (not clicky) resonates

Did you know the oldest public access Unix system M-NET / arbornet.org are now maintained by SDF.ORG? M-NET currently enjoys preservation thanks to Dan Cross here under FreeBSD but the ALTOS still exists #retrocomputing #vintagecomputing #community

Check out my new podcast/youtube video with Stephen Jones of the Interim Computing Museum (formerly of the Living Computer Museum!) @sdforg.bsky.social you can support them with a tax-deductible and matched donation and visit them now! youtu.be/EFkxiLBSjTo?... icm.museum

In rogue the bat has a secret defense that makes it undefeatable under digital OSF1 #retrogaming #rogue #gaming #ascii

I noticed a price tag on this Apple IIc box: December 18, 1987, $949.00 IMHO, that is pricey for a computer that came out in 1984! This was just for the computer, no monitor or mouse.

Thanks to Alex of Rabbit Hole computing we are converting the remaining SCSI disk drives on our remote systems to #zuluscsi Here is hkypux, an HP9000/715 running HP/UX 10.20 icm.museum #server #retrocomputing #vintagecomputing #scsi #emulation

Bruce and Jeff have made progress on the MITS Altair 8800. It’s doing deposits and examines now with some success. #intel #1970s #altair #homecomputer #retrocomputing #vintagecomputing #microprocessor

Portland Retro Gaming Expo attendees got their first try at an early video game: Space War! On the IMLAC PDS-1. Would you like to support us so we can attend future events? icm.museum #prge #portland #retrogaming #vintagecomputing #retrocomputing #classicgaming #gaming

Adrian @adriansdigitalbasement.com had fun at ICF and a few weeks later brought people to the ICM booth at #PRGE would you like to help us? icm.museum #vintagecomputing #retrogaming #retrocomputing

Look what the nice folks at the PRGE Intellivision booth gave me! Thanks Mark!
