@RetroNora7734 RS232 IO?

AN2000- terminal developed by Gdańsk University of Technology and produced by Unitra Magmor. This unit is from 1985 and has a serial number of 015!
The terminal consists of keyboard with electronics and Neptun 157 monitor (Neptun 156 with PSU for the keyboard part) that I miss.

Happy International 555 Timer Day!, the 5th of the 5th.
The 555 design is 55 years old this year.
Salute to the great Hans Camenzind 🫡

Several electronics Youtubers including yours truly will be releasing tribute videos today. I'll release mine at 5:55pm Sydney time.

Minimalist game console #ZeroTiny with Raspberry Pi Zero 1/Zero 2 module and bare-metal #PiLibSDK library. I love that clear sound of the MP3 player! 🥰Games will be coming soon. https://t.co/wUkj0x77e3

@IanSJohnston They are quite durable but many of them disintegrating especially when kerb is mounted with HGV making this scheme absolute epic fail. We never used them again. pre-cast concrete and granite is a king.

[Legacy Devices @LegacyDevices_]

@IanSJohnston Highways engineer here... this was a silly scheme few years back where plastic kerbs were being used due to weight limit (H&S silliness) and tested as a pilot project. Kerbs were meant to be filled with concrete but they this would make them heavy closing the vicious circle.
