The PDP-7 uses a destructive read restore cycle which has caused bits to flip in the core. Writing small diagnostics on the front panel is a fun way to zero in on faults while crawling the backplane. #vintagecomputer #boeing #pdp7 #unix #vintagecomputing

Hängt davon ab, wann "damals" ist. Ursprünglich wurde Unix auf PDP7 und PDP11 entwickelt, klassisches CISC. Die erste Runde Unix-Workstations hatte auch klassische CISC-Mikroprozessoren: vor allem der 68k (z.B. Sun, HP) und NS32k (Siemens MX). Dann erst kamen die RISC-Prozessoren und mit ihnen dann

From Jurrasic Park to SpacemiT K3, RISC is where it's at. Get ready for the #RISC-V MC taking place at the #Linux Plumbers Conference in #Prague next month.
This microconference is happening October 6 and is organized by @pdp7.bsky.social. #Kernel devs assemble.

In the early days..PDP7..showing my age..a hack..was sort of recognized like a “verbal attaboy” and something to feel good about. In model train world an improvement in operation .. been there done that and some layouts have been landfill for decades.

I'm surprised that a Google workspace sending mail to Gmail is getting bounced back.
Same thing happened when I emailed my pdx kernel meetup attendees from pdp7.com. The people on gmail all bounced.

I've noticed a big increase of Gmail bouncing messages over the last week. My personal email domain pdp7.com is a google workspace and it forwards all my mailing list traffic to my personal gmail (due to 15 years of label filters that I've not wanted to re-do).

It really wasn't meant to be a correction, as a bit of education
My first encounter with a computer with a disk drive was in 72 in college. I got a job as a PDP7 operator
The disk drive held 5 meg of data, was in a cabinet the size of a refrigerator.
And the console was 110 baud teletype mach

@pdp7 Did you only do that one youtube video that you tweeted sometime back, or are there other ones? Also, I lost the link for that. :'(

We get ssh replacing telnet as we start hardening against bad actors.
It's been 50 years since the PDP7, but our shell still talks to an abstracted teletype. Their design decisions still affect us now. And the technology influences how it's used. #bangbangconwest

De los clàsicos, conoces Angband? El único que he jugado casi ininterrumpidamente desde hace (glubs) más de 30 años.
Empecé jugando en un PDP7 en uni a su predecesor (Moria), de hecho. Sigue en desarrollo activo como Nethack.
