Hey lovely Mastodon folk. I've just released an HP-35, HP-45, HP-80 simulator called HP-1973 to celebrate the 50th anniversary of the HP-45 calculator. (Free) standalone versions for Mac and WIndows (no need for any Python installation or knowledge) & Python source for Linux. It's been a coding marathon, so it'd mean a lot to me if you could boost this post, so it gets in front of the right people. Download here: https://sarahkmarr.com/retrohp1973.html Enjoy. #retrocomputing#calculators#python#coding#rpn
The master tapes have been found by the ReBoot Rewind documentary crew and they need our help with finding a working D1 tape deck to digitize them.
Crossposting this from Facebook:
🚨THE MASTER TAPES EXIST AND WE NEED YOUR HELP🚨 THIS IS NOT A DRILL🚨
Hey you, YES YOU! We have some good news to share!
For years, there have been rumours circulating about the status of the original PAL D1 masters of ReBoot and whether they still exist. After visiting Mainframe Studios yesterday to take a look through their ReBoot archives, we’re happy to confirm that the masters are all here, for every episode of the show!
Getting a proper digital transfer of the D1 masters is high priority item for us. It would mean having the entire series in the best possible picture and sound quality, presented as accurately as the day it was rendered. There’s also a library of additional ReBoot content (animation tests, toy commercials, Electronic Arts video game footage, IMAX content) that is currently stuck on the D1 format and we need to preserve it for the future. This would obviously benefit the documentary but ultimately, it would benefit the fans the most!
Here’s where we need help. We need a working D1 tape deck to capture all these tapes. Mainframe hasn’t had one for years. We haven’t been able to find anyone in Vancouver, British Columbia, or even all of Canada that has one of these tape decks. We’d greatly prefer buying or renting one of these decks so that the tapes can be captured locally, without needing to ship them.
If anyone has a lead on where we might be able to get one of these decks, please contact us!
Did you write code for #Psion machines in the #80s and #90s?
We're calling for you to open source your code!
I'm working with a group of enthusiasts, building a library of information about the SIBO/EPOC16 platform. Your old code could give valuable insight, as well as encourage people to write new code.
We're especially interested in old C and #x86#assembly.
Upload it to your public repository of choice, and set it free!
This is the best photo of magnetic core memory I've ever taken. IBM, early 60s. Shot with a microscope lens mounted on a 35mm B&W digital camera. No post! (I got into the habit of never doing any post-processing while documenting historic artifacts for the museum. Photoshop not allowed!) #retrocomputing#photography#rcsri
I used this shot for the cover of my book of images from our museum:
Also in 1983, Lucasfilm (later Pixar) made the first high-resolution computer-generated image that was supposed to be near-photorealistic and "a single-frame movie".
Have you ever tried emulating #Windows98 on a #Ryzen system and had it crash spectacularly? Just within the last year or so, someone's written a patch for 95/98/98SE to fix it!
There's a floppy image you can boot your VM from, which will patch and fix your Win9x install even if it's partially installed and you hit the Explorer crash, so it doesn't even matter hugely where/when in the installation process you apply it. https://github.com/JHRobotics/patcher9x/releases/
This is your friendly reminder that I make and sell delightful miniature retrocomputers like TRS-80s, Osborne Ones, and the occasional big friends like Connection Machines and Crays.
I'm a retired nerd who's living the dream. Well, if your dream is working in your garage on tiny art machines. 😺 ⚙️ #retrocomputing#miniatures#trs80#cray#shamelessSelfPromotion https://store.transmutable.com/
I finished dumping 99.99% of a very old, damaged, backup CDROM that was previously unreadable. It took 3 days and I was super excited to find what old data I put on it. The disc had UDF sessions, because that was common at the time for just Adding Files non-rewritable media.
So I mount that shit in my Windows 98SE box, and lo and behold, this is all that was on it.
I would be absolutely upset if it wasn't so fucking funny
I think I now own the coolest wall clock I could imagine haha. Leaving it in its box till I move in a couple weeks. After I get settled I’ll decide where to put it. Not quite #retrocomputing but I think it counts. 😀
For nearly 5 years, I've been trying to figure out what this adapter is supposed to connect to. It's still a mystery. Someday, the right person is going to see this post and they'll finally solve this puzzle.
