I have my #pidp8 sitting in my shelf shelf for a while now. I did some #basic coding in #os8 so far. Yesterday, I finally found some time to toggle in some very basic demo programs, like adding two integers. It was much fun! 😊

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.

@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! 😅

Yesterday I successfully finished #soldering my #PiDP8 kit. Worked great! 😊

I plan to mount the #RaspberryPi (running #SimH) to the outside of the back plane of the wooden housing. RasPi and the main PCB will be connected with a ribbon cable running through the back plane. This way, I can access all ports from the RasPi (SD, USB, Ethernet).

So, cool: One of my #Christmas gifts was a DIY kit for a #PiDP8. I am so exited to build it and toggle some progs in. 😀

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

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. #PiDP8

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

#pidp8 ongoing panel test on #gentoo #GenBerry 😀

Time to play #pidp8 :-)

I guess I should actually do one of those #introduction type toots now that I've found my new fediverse home. I used to be @MatStace@octodon.social in case you want to check out the sorts of nonsense I toot about.

#London UK based human-shaped computerist (he/him), by day I pay the bills by turning things off and on again (these days redeploying containers and removing old ones), by night I do more computery things, play with the likes of docker/kubernetes/other #homelab type things

I'm also mess around with various #electronics and #amateurradio things, and have recently started messing around with #homeautomation using #homeassistant, and assembling my stash of #retrocomputer kits (#altairduino, #rc2014, #pidp8 and #pidp11 )
