@revspace After a few days of work, implementing 3 missing libc functions, repairing an extra 4MB of RAM, hacking around toolchain issues, we finally got Lynx 2.8.2 compiled and running on the VAX-11/750 (in 4.3 BSD Quasijarus)! That means we got to browse the (non-HTTPS) web using no equipment or parts newer than 1986 this side of the network (besides the AUI 10Base-T phy).

Hi all, we did our annual PDP-12 demo in Dr. Ted Pedersen's architecture class on Tuesday, and it went really well.

In cleaning up / reorganizing after showing off our artifacts, I realized that we have something that I haven't seen on @bitsavers, but I maybe just didn't know where to look. It's a big poster of PDP-12 instructions -- it's kind of like the pocket reference in poster format. It is about 9.5x30 inches (24x76 cm). I scanned it in two pieces on the office machine and stitched it together with GIMP. I'll try to make a PDF version with OCR text. @bitsavers #vintagecomputing #retrocomputing #pdp12 #pdp #dec #umdpdp12

Well @retrobytes goes very nerdy¹ about the DEC PDP-10 and builds a replica in the form of a PiDP-10 in an epic soldering montage.

He also waxes lyrical about the TOPS-10 OS for the PDP-10 and it's ancestry to CP/M, MS-DOS and via another route to Microsoft BASIC and a lot lot more more!

Connections going every which way that even James Burke would appreciate 😁

¹ Clearly the best kind of nerdy 🙂👌

Reading MuseumReading’s DIGITAL Revolution ExhibitionGet switched on with Reading’s DIGITAL Revolution – a new and unique mixed-media exhibition celebrating the life and times of Reading’s digital industries. Sixty years ago, a start-up American computer company called Digital Equipment Corporation (DEC) opened its first office at 11 Castle Street. Beginning with just two employees, DEC grew exponentially with a workforce of more than 2,000. Since 1964 Reading has evolved into one of the largest tech clusters in the UK, with more than 11,000 ICT businesses calling the greater Reading area home. The exhibition includes the DEC talk voice synthesizer famously used by Stephen Hawking whose account was with Reading DEC. You can view a unique collection of rare and vintage computing equipment on loan exclusively from Bletchley’s Park’s National Museum of Computing and private collectors across the UK. A video wall installation features reflections on the growth of Reading’s ICT industry from key figures in Reading’s digital story. While innovative new digital artwork includes a large-scale mural exploring Reading’s digital future. The exhibition is made possible by the National Lottery Heritage Fund and in partnership with The National Museum of Computing, Reading’s Digital Revolution traces the origins of Reading’s tech sector, sharing ideas about its influence on our town’s present and future.

I'd been a member of #SDF for about a year or so when I posted to #BBoard to get rid of a load of 10-12 year old #DEC workstations and a server that my wife's ex left in his house. Someone responded, and we met down in Lewisville or somewhere. I don't know if that person was able to get them going. I have this hope/wish that they're still running somewhere and now 30ish-year-old computers living their lives.

1/ Just because, here's my LSI-11 desktop - It works, they used much better capacitors in those days.

Way back when, the LSI-11 was often used to teach people Operating Systems and Compiler Design, and in my CS degree in 1986 we'd fiddle with MINIX on these things, and deal with re-writing different low-level UNIX things. Life was much easier with only 50 instructions to work with.
