MK51, a single-chip RPN calculator from Электроника. The program ROM is on the right side, but bits are not surface visible. Maybe I can reveal them with delayering or a Dash etch.

Toshiba TC54256 from a Texas Instruments Education TI 81 graphing calculator. This is an OTP ROM, an EPROM with no quartz window for erasure. You can read it electrically with a standard reader, but you won't be photographing the bits with an optical microscope like a mask ROM. cc ticalc.org

Intel's Israel site was opened in 1974, Intel's first design and development center outside the US. In this thread, I'll look at some of the important vintage chips designed at Intel Israel, such as the 8088 processor. 1/10

I love the WaveDrom plugin for VisualCode. It's so nice to be able to do timing diagrams right there and not have to use a standalone app or online service.

TIL "breadboard" comes from people using literal bread cutting boards as the base for their electronics back in the day

You'd almost think speculative execution is a fundamentally flawed idea

I have a dream. It's not a big dream, it's just a little dream. My dream - and I hope you don't find this too crazy - is that I will one day be rich enough that I can solve my printer problems by throwing it out the window.

OK... they tell me I should go on Twitter to tell a bit about the coming PiDP-10. And tell the story of the past year. Scary. social? media? Not really me. But: in a month or two, you can have a PDP-10 in your living room. groups.google.com/g/pidp-10 #PiDP10

So now there are three PiDP replicas, each to tell its own story of computer history - or the DEC part of it. The 10, though, has been a long time project - since 2018. But the injection molded case is in production, so it won't be long now. #PDP11 #PDP8 #PDP10

Oscar Vermeulen glitch And we need a special edition PiDP 11/40 to be a front end 😀

I did have to pause and check that this wasn't a @NanoRaptor project :-)

MIT CSAIL ENIAC did not have a concept of “byte”. What is this really called?

MIT CSAIL Not a byte, not RAM, but it is from ENIAC in 1946. That tube module holds one decimal digit. It's from an "accumulator", which counts and stores numbers. It uses 10 tubes in a ring counter to hold the values 0 through 9. Bytes didn't exist at the time. archive.computerhistory.org/resources/text…

🇺🇦 Nonstandard Nerd I worked at Apparat as well .. I was the last support technician for NEWDOS/80. Good times while it lasted!

New fastest shortest-path algorithm in 41 years! Tsinghua researchers broke Dijkstra’s 1984 “sorting barrier,” achieving O(m log^(2/3) n) time. This means faster route planning, less traffic, cheaper deliveries, and more efficient networks - and a CS curriculum revamp =)
