Hi all, you're invited to the Update computer club[0] public lecture series "Updateringar"[1]! Update is a Swedish computer club founded in 1983 whose members tinker with all kinds of computers, from Raspberry Pi to PDP-12. The club has a big collection of historic computers. In this lecture series we'll talk about everything related to computers: Historic and modern computers, operating systems, programming, hardware projects, creating art with computers, building a computer museum, and more. When: 2021-05-08, 19:00 CEST Where: https://bbb.cryptoparty.se/b/upd-0mo-m2u-aq8 Forth: from the minicomputer to the microcontroller Forth is an almost esoteric programming language in the eyes of most modern programmers, but still worth learning if only to expand your horizon. On modern microcontrollers the strengths that made Forth stand out in on 1970s minicomputers are relevant once again: fast enough execution, low worst case latency, full control over the system, powerful metaprogramming, and interactive development. This presentation will show how to overcome the initially near vertical learning curve and get the Mecrisp Stellaris Forth system running on a STM32 microcontroller without breaking the bank. Prior exposure to microcontrollers or assembler is helpful, but not required. Once the Forth system is running we will use it to explore either the hardware it's running on or its implementation and available implementation tradeoffs. Jan Bramkamp (CCCHB) The lecture is free and open to everyone. Upcoming: 2021-06-12, 19:00: How to start and run a computer museum. Thiemo Eddiks (Oldenburger Computer-Museum) Hope to see you there, Anke P.S.: I hope this is not too offtopic, but I assume there are people interested in Forth here.
