Dear #RetroComputing #PDP8 enthusiasts, do any of you have a neglected #PiDP8 that you no longer use? Was it a fun lockdown toy that you no longer interact with? Are you within postal distance of #London? If so, get in touch: I'm working on a project in PAL assembler and would love to have the front switches and lights, but not enough to order and assemble the thing.

I can replace the #SBC inside, if you already scavenged it for something else! I just wonder if anyone has one taking up space that they'd rather use for something else these days.

@kenshirriff Thx for the info, Master Ken! 🤗 It was a dream come true when I visited the CHM in May 2013. ❤️ I wish I can do it again some fine day in the future. It would be amazing to then be able to meet & greet & hang out a bit with you and the „gang“ around . Until then I‘ll play with my and maybe oder & build a or even kit. 🙈🤓 Have a great Sunday! ☀️

@rzbrk After I finished my kit a few weeks ago now I‘m tempted to order the kit! 🙈🤓 Or even the kit?! 😳 But they’re not cheap and shipping costs are crazy, too!

@rzbrk Mein Informatik LK Lehrer (damals, Mitte der 80er) war der Knaller und wir hatten sowohl eine PDP 8/e, als auch eine PDP 11/23 in der Schule! 🤩 Damals war ich allerdings eher auf dem Turbo Pascal Trip (BGI Treiber für EGA Grafik! 😂) und konnte mit diesen geschichtsträchtigen Maschinen von nicht viel anfangen. 🤷‍♂️ Würde er noch leben, hätte er *sicher* auch eine und/oder zuhause!

@rzbrk Yeah! 🤩 I‘d say „welcome to the club“ but I was late to the party and built my own kit just a few weeks ago. Love programming it via the front switches in octal machine code! 🤓

@rzbrk No glue necessary, I just inserted the palm rest bar into the side pieces.

Do you own a PiDP-8, too?

Best moments when two hobbies come together. Here I added a 3D printed, very solid stand to my self-assembled PiDP-8 replica of a . The hand rest barely fit diagonally onto the print bed, phew! Together with four silicone bumpers the whole thing doesn’t move a bit on the desk. 👌

Finished & working! ✅
Only thing left to do now: Design and 3d-print a stand for it to have a good viewing and operating angle when sitting at the desk. Anyone any idea or already made a stand for a steep angle? 😳
(I wonder whether Global Thermonuclear War from runs on the PDP-8, too. 😂)

Almost finished the kit today! Loads of soldering! Just one bad LED had to be fixed by replacing it. It works pretty well and it’s awesome! The does all the emulation. Can’t wait to write programs via the front switches – and play SpaceWar! later on. But before that I have to finish the casing! 👉 www2.rdrop.com/~paulmck/projec

Over a week ago I received my happily expected kit – but haven’t found the time yet to solder and assemble it! 🙈 The Zero 2, however, already runs the emulator. 😊 That’s a LOAD of LEDs to solder accurately. 😅

One day down, maybe two more days to go on a #PDP8 numerical simulation run. So far, its accuracy is pretty close to modern IEEE double precision.

I'm so glad that the #PiDP8 runs roughly 23× faster than the real thing. I'd have had to budget nearly 10 weeks (at roughly 750 W) on real DEC hardware.

#fortran

@wuffel On the #RaspberryPi in the #PiDP8 #SimH with OS/8 is running.

FINALLY!!!! The #PiDP8 kit is finished and sittting in the shelf waiting to be played with. Really cool! 😅

I’m super excited today and have @slofunk@twitter.com to thank. Jamie made me aware of this sweet kit:

obsolescence.wixsite.com/obsol

He and I were both able to snag a kit from the next batch. Thanks to my supporters, the cost to entry was very low. Thanks to all of you! More to come.

It seems that my #pidp8 have a trouble with 3 leds when i launch the pidp8i-test program ... However they're good (tested).
