Happy Birthday Kevin! 🎂

A PDP-8 computer in a new-to-me blue & blue color scheme. I learned to program on one with the more typical red-and-gold scheme, and I’ve seen a hideous two+tome green variant, too.

Went to VCF SoCal today and there was a PDP-8 in a new-to-me color scheme. Learned to program on one of these in 1973.

@adventofcomp.bsky.social gave a hilarious talk about INTERCAL, the Compiler Language With No Pronounceable Acronym

Ahh, the vents on the back tricked me. I've only ever seen the plastic cased version IRL. Nice machines! :)

Commodore 128 - Mmmm
PET II - Sweet
Amiga 3000 ? - Ooooh

AI image of a 'Correctly-wired UK plug' which is anything but correctly wired, with the live wire not going into the fuse, a mystery grey wire, and the neutral being a tiny wire between the fuse and the third pin...

AI intends to kill us all

I've always used DSDD disks on the S1/V9k without issue. I think the correct disks are 96tpi quad density (Same as used on 80track BBC drives). Not sure I'd trust HD media.
Oddly enough, I have a sealed box of Victor branded 1.2Mb HD media that was for their later PC compatibles.

I finally got around to putting a video together for the North Star Horizon. youtu.be/gFO5XHTvKG8?...

Yeah, I had trouble with CP/M-86 on my HD equipped Sirius. Seems to really unlike the first partition being drive A.

Also have a Z80 board I haven't tried yet. I believe the software is on archive.org

The future of robotics is here

Customer - "Can you print this on a T-Shirt?"
Me - "Yes.... Did you use AI to create this?"

Customer - "Yeah, ChatGPT is great!"
Me - "Errr, your phoenix appears to have two heads"

Customer - "But it looks good. It'll be fine. AI is great!"
<SIGH> 🤦

Nevermind, here's a Mandelbrot I printed to cheer you up! 😉

Nice! My high score is 32768 on the Apple ][ version of VisiCalc 😉

What is inside this clear Sun SPARCstation LX? Disassembly, BlueSCSI hard drive backup, PSU recap YouTube video by BigBadBench

I picked up this clear Sun SPARCstation LX a couple weeks ago. I was told that it was a special machine used for trade shows. Let's take it apart, back up its hard drive with BlueSCSI initiator mode, and start recapping the power supply. Saturday noon EST. youtube.com/live/W6tjUSo...

Revisiting this now that I have a #C64U

Fewer characters available than on a C128 or the teletype so I had to fudge the numbers a bit, but I took the opportunity to add colour!

Also I can turn on turbo mode and have the whole thing generated in seconds by an emulated 64MHz 6502 😀

50 years of KIM-1 and me

retro.hansotten.nl/50-years-of-...

I have collected some KIM-1's over the years. The first KIM-1 in 1978, and now I have nine original KIM-1s, from first edition to Rev A, B, D, E , 2x F, 2xG.

And several reproductions with 6532's as replacements.

Sadly not a Cromemco but it is MP/M running on an Altos :)

Hmm, I might be bringing a machine that can play Zork 1,2 & 3 all at the same time on a single Z80 :)

I have big plans for spinny CRT

Usagi's video today really hit close to home with the IV/90 I'm still trying to understand.

i made a flappy bird clone that uses your folding phone as the controller

Zu sehen ist ein Ausschnitt einer PC Tastatur mit den 10 Funktionstasten links sowie dem Alphanumerischen Feld rechts daneben. in jeder Taste ist ein kleines Fenster mit einem s/w LCD, dass mit eher schlechtem Kontrast die aktuelle Tastenbelegung zeigt. Also z.B. ein großes 'A' mit Shift, ein Kleines ohne.

🎅Türchen 20: LCD-Tastatur🖥️

An unserem 5150 PC hängt nicht IBM's '83-Key' Tastatur, sondern ein Luxus-Exemplar mit kleinen 14x8 LCD in jeder Taste. Diese zeigen, in Echtzeit und abhängig von Shift/Ctrl/Alt, das jeweils aktuelle Zeichen an.

Picture of a citation at the end of a paper. The citation says: 15. "Flex and the ICL Perq2" M.Stanley. University Computing Vol 8, No 2, Summer 1986.

Has anyone ever heard of a (UK?) journal called University Computing? Know where I could find archives? Long shot, but this paper could contain info that helps us open-source a remarkable operating system developed by the UK MoD in the 1970s and 1980s. Boosts appreciated!

The review of Lotus 123 on page 132?

Yep, There were adaptors available that had an RCA jack with composite video.

I've had to make one up in the past. Just used the connector from an MFM HD cable and jumpered the top row to the bottom.

Ahh, could be then! :)

Same revision, yes. Photo is from the museum but I doubt it is the exact unit
