The VAX11/780 wasn't just a star computer of digital equipment, but No.1 at CoCom's top10 international export charts. With 1.0 VUP DEC challenged IBM 360 systems and beat them in efficiency.
Launched in late 70s, the legendary 32bit computer was running @ 5Mhz on a KA780 CPU with up to 128 MByte of RAM. In VMScluster systems of 2/4 they delivered up to 3.5 VUPs.

All this talk about #infocom and #zork - all I care about is the original #dungeon game that ran on larger (than pc) computers. #dec10 #tops20 #vax11

The WELL: первое онлайн-сообщество хиппи, хакеров и писателей

Современный интернет построен на сообществах. Этот нехитрый принцип прекрасно понимали создатели социальных сетей, до них — разработчики тематических форумов, а еще раньше — администраторы новостных групп Usenet. Однако задолго до появления интернета существовало как минимум одно сетевое сообщество, объединявшее по интересам множество совершенно разных людей: писателей, инженеров, музыкантов, хакеров и хиппи. Появилось оно в далёком 1985 году, а в 1997-м журнал Wired назвал его «самым влиятельным онлайн-сообществом в мире». Вы еще не слышали про «The WELL»? Тогда мы идём к вам! Что такое WELL?

One of the lesser-known units of time measurement is the microfortnight.

The microfortnight unit exists in VAX/VMS because the console hardware clock interrupts used in the VAX-11/730 console measure elapsed time in a unitthat differs from a second. This hardware interrupt frequency choice affects timeouts related to console operations.

(Note: Once VAX/VMS is booted, things related to timekeeping and timers all work as expected, and seconds are a second in length. But when running the console program, not so much.)

This also led to the creation of the SD730 Fixed Head Solar Horologue option; a sundial intended to assist with tinekeeping.

Hall Of Technical Documentation Weirdness - Slashdot

The creator of that little gem was Dick Hustvedt, a brilliant engineer with a wicked sense of humor. He was one of the inventors of VAXclusters, as well as of the SD730 Solar Horologue Option - see end of this post. When in the VMS SYSGEN utility, and you asked for a list of the parameters, the list...

Apropos of nothing, VAX-11/751 was a rackmount variant of the VAX-11/750, and intended for OEM integration. Aside from reorganizing the internals to fit into the rack, it was otherwise identical to the VAX-11/750.

While all released models of VAX were air-cooled, the VAX 9000 “mainframe” models were originally planned to be water cooled. Engineers were able to sufficiently cool the VAX 9000 with air and this avoiding the added plumbing, which led to the “Aridus“ variant of “Aquarius” shipping.

@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).

Decided to display the VAX-11/750 at the @revspace open day yesterday. All the hard work repairing it seems to have paid off, managed to get 14 hours of uptime out of it before shutting it down at the end of the day! #unix #retrocomputing #dec #vax11 #minicomputer #unixhistory #bsd

To restore the Robotron K1840 (VAX11/780), the PDP11/03 must first be running in the correct configuration. For this I am looking for a working CPU card like this one.
Who can help?

Continue working on the Robotron K1840 with @dm2lct
Check contacts and test the PDP11 memory for reading the microcode.

El 25 de octubre de 1977, fue comercializada la súper mini computadora VAX-11/780 de 32 bits desarrollada por DEC, con floppy drive de 6” y 128 a 4 Mb de RAM
