@tubetime I expect they’re exaggerating like HDD manufacturers are known to do, and it’s actually more like 8”. I’m more impressed with the 50K hour. They don’t specify what’s rated at 50K hours, but that’s definitely a big number!

First thing I do when encountering a file of unknown format is to feed it to the file unix utility. Sometimes it would say it's "data", then well, good luck.

@tubetime At least 3 years ago this guy had a copy running under Windows7 and was willing to convert axd files to dwg . https://www.worldcadaccess.com/blog/2015/11/got-axd-files-we-got-actrix-2000-for-translation.html

@tubetime reminds me of Kodak's .KDC and trying to make the files usable with high sierra and windows 7 this year. They should have just kept making kodachrome and EK6 instead. (But in all seriousness the DC120 is a fun camera)

@tubetime calling it RISC V was a mistake, rather than RISC Free

@tubetime And they're properly floppy. Neat.

@tubetime I still have them.

@tubetime I’m very much envious of a plastic sleeve allowing me to carry five three-and-one-quarter inch floppy diskettes in my pocket. LOOK OUT YALL COMING AT YOU!

@tubetime @billgoats In the 70s and 80s smoking was very popular. These computers are just a reflection of this habit.

@tubetime RSVP that guy’s monitor!

@tubetime
When you listen to YouTube telling you "don't change the 30 years old capacitors"...

@tubetime Not the typical packaging for a coil, but it’s still just a coil.

@tubetime I want to see the engineering drawing for the mold press. 😁

Also the die attach machine 3D rendering.

@tubetime electrical enginer said do a flip

@tubetime Doesn't forcing electrons to take tight corners release all sorts of interesting radiation?

@tubetime ok where do i buy one?

@tubetime I wonder how this would work as an oscilloscope tube design. It's all electrostatic so in theory you can deflect pretty fast...

@tubetime
Maybe it was designed by generative AI

@tubetime Well, these keyboards also have a letter on the key to the right of L that you type using the pinkie finger...

@tubetime @wawik Can’t remember if this is reviving a Finch or a Wren but Usagi Electric does a lot of really old mini and larger computer restoration. https://youtu.be/hbc6n3Ln3bM?si=baaNzTLUGhBgd-zg

1985 illustration of a Maxtor 5 1/4" hard drive.

@tubetime very cool. I had a CDC Wren half height drive at one point from some time shortly after that line was bought by Seagate, it had Seagate labels but the firmware said CDC Wren

@tubetime I like how the 10MB HDD can transfer 5MB/s. I can't remember when was the last time I had a storage device that I could read end-to-end in mere seconds.

@tubetime
The bottom-left drive isn't a floppy driver ... but a cassette tape drive !
I'm very curious about this thing now !

@tubetime There seems to be a real emphasis on power draw. Something almost forgotten on todays’ desktops.

@tubetime Back in the early days of EGA, I came across a little program called "egafont" that was a TSR that changed the text mode font. It came with a few fonts and I later wrote an editor and made more. I even disassembled it at one point (with Debug!) to see how it worked. It was very reliable. If I stuck with the conventional font size, it worked with everything.

I'm sure that "mode" command used this same method to switch to a Cyrillic font.

got it working! fake graphics cursor in text mode DOS.

@tubetime I always wondered how they did that. I figured it had something to do with the way EGA/VGA handle fonts, but I never learned the specifics.

@tubetime
Was it Central Point who also had a rich DOS gui.

PCTools that became something else after.

Back in the days of QEMM and Word Perfect 6 or 7 which also had something similar.

@tubetime I remember the first time I saw that cursor on my screen and thinking to myself “I need to know how they did that.” :blobaww:

@tubetime
Perfect. Thanks!!

@tubetime Watching it now. A delight! Thank you for linking.

there are 3 26-pin connectors. there are four synchros inside, a motor, a "digital analog converter", and two large potentiometers. there's also a gear train and an electronics module on top.

@tubetime Did you ever see my mystery three digit displays? This one displays values from 0 to 999 according to a synchro format input. 700 degrees from 0 to 999. https://www.youtube.com/watch?v=v7jQK4ueLBo

@tubetime sorry I missed it. Thanks for the pictures!

@tubetime I’m sorry to miss the last one. Good hunting.

@tubetime holy crap! I had no idea this was here! When does it resume and are the retro-computing items mostly for parts only or do they also have working collector worthy units?

@tubetime Great thread, thanks!

@tubetime I saw the image and instantly thought "Grimeton!" 😆 glad to see I was spot on, it's a fantastically interesting museum to visit.

@tubetime aka #Rundfunk

@tubetime I imagine it's the RS/6000 emitting “Let me die… let me" and the adapter returning “Not today, not foever” :)

@tubetime wait-wait-wait... this one?

I'm at the "blink an LED" stage of bringing it up.

@tubetime

Brain the size of a planet and all they
have me doing is blink an LED

@tubetime
“Rather complex”… it connects to MicroChannel slots on two different computers.🙂
