Most people are familiar with Niklaus Wirth's sequence of languages [EULER, PL360, Algol W,] Pascal, [Modula,] Modula-2, Oberon. But a parallel sequence, designed at #Xerox #PARC and #DEC System Research Center, is not so well known: MPL, Mesa, Cedar, Modula-2+, Modula-3. I … decided to capture as much of the history as possible of these "shadow" languages:

Внутреннее устройство ОС RT-11: копаемся в исходом коде. Часть первая

RT-11 — это операционная система из 1970-х годов для популярного в то время мини-компьютера PDP-11 фирмы DEC. В СССР известна под именами Электроника 60, ДВК, БК 0011М. Для тех, кто любит изучать чужой код в поисках инженерной эстетики — дальнейшее изложение.

Occasionally I work on my PDP11/70 emulator (toy-project, in my spare time). The latest version can run BSD 2.11 multi-user on an ESP32-S3. Even though I wrote the emulator myself, I'm still amazed about the physical reduction in size. On the left in the picture below you see the original device (the thing in the 19" rack with all the lights and switches), on the right you see the ESP32: smaller than my hand!

In the late 1970s Interlisp was ported to DEC VAX computers under Berkeley Unix. These papers reported on the project and its challenges.

I sort of miss programming on a DECwriter (teletype). There was something satisfying in literally pushing a key down and seeing punch-paper tape spew out. You were creating something. Now, everything you do is just feeding an LLM without any real result.

Trying out #Mastodonochrome by @simontatham on my trusty old #DEC #VT420 terminal.
Generally works ok, but all normal text is flashing for some reason. And it's not respecting my ISO-8859-1 codepage preference.
But it's fun that it's running at all! It does have a #BBS feeling. 😄

Boards of Canada - Olson, on a PDP-1 from 1959. 🎶

”The PDP-1 was never intended to produce audio […] It does however have six "program flags," which are flip-flops wired to six light bulbs on the control panel. A CPU instruction provides the ability to turn these light bulbs on or off via software.”

DEC. История в лицах. PDP-1 (I)

Памяти Кеннета Олсена, родившегося в этот день ровно 100 лет назад Уже глубоко за полночь 1 декабря 1959 года, а именно в 1:30, едва Лоис Андерсон уложила спать третьего, младшего ребенка в семье, раздался телефонный звонок. Из отеля «Статлер Хилтон» в Бостоне Харлан Андерсон позвонил супруге, предупредив о том, что не сможет приехать ночевать домой: прототип PDP-1, исправно работавший в стенах DEC, по известному закону подлости отказывался работать в выставочном зале. До открытия компьютерной конференции оставалось менее восьми часов...

[Перевод] Бунт против IBM или как хакеры сломали систему и сделали компьютеры персональными

В 1974 году Тед Нельсон явил миру литературного кентавра — книгу, столь же эксцентричную, как и ее создатель. Чтобы оплачивать счета, Нельсон вынужденно читал лекции по социологии в Иллинойсском университете — хотя в душе был технологическим Че Геварой. Еще в свингующие шестидесятые он родил идею «гипертекста» — системы, связывающей документы невидимыми нитями, и окрестил ее «Проектом Ксанаду». Проект, правда, походил на линию горизонта — прекрасен, грандиозен, но вечно в стадии «почти готово». Нельсона терзала одна несправедливость. Его коллеги-радикалы смотрели на компьютеры с суеверным ужасом — как средневековые крестьяне на алхимиков. Для бунтующей контркультуры тогдашние ЭВМ казались железными церберами. Нельсон не спорил: да, сейчас эти машины используют жестоко. Но в них он видел не кандалы, а ключ от темницы. Вперед, в 70-е! →
