When a CRT Isn’t Retro Enough: LEDs

Posted on by

When we think of an old-style computer terminal, it has a CRT screen: either one of the big 1970s VDUs with integrated keyboard, or maybe one from a later decade with more svelte styling. You would have found other displays in use in previous decades though, and one of them came our way that we think it worthy of sharing.

[Dan Julio] was given several tubes of Siemens DL1416B 4-digit 17-segment LED displays by a friend, and decided to use them as an unusual retro display for his terminal project. These devices are an alphanumeric display with a parallel interface …read more

By the Glow of the CRT

If you are a certain age, you probably remember writing software (or playing Adventure) bathed in an amber or green light from an old CRT terminal. If you are even older, you might have found it way better than punching cards, but that’s another story. [Tobi] wanted to relive those days (well, sounds like he is too young to have lived them to start with) so he hooked up a VT220 terminal to his Linux box.

This isn’t that surprising. Linux’s forefather, Unix, expected these kind of terminals (or a hard copy TeleType) and all the trappings for working with …read more

Dumb Terminals And Raspberry Pis

Posted on by

Back in the old days, the cool kids didn’t have an Apple II or a Trash-80. The cool kids had jobs, and those jobs had Vaxxen all over the place. The usual way of working with a Vax would have been a terminal, a VT220 at least, or in the case of [Sudos]’ experiments with a Raspberry Pi, A DEC VT510, a single session, text only serial terminal.

Usually, when we see a ‘new hardware stuffed into old tech’ project like this, the idea is simply to find a use for the old hardware. That makes sense; a dumb terminal …read more

A Minitel Terminal As A USB Linux Terminal

Posted on by

If you paid a visit to France in the 1980s the chances are you’d have been surprised to see a little brown screen and keyboard sitting next to the telephones wherever you went. At the time, it was another reason apart from the food, wine, and super-fast trains to envy our Gallic cousins. This was Minitel, their take on the cutting-edge of online data services of the day.

Minitel stood apart from similar services of the day in most other countries, because of its business model. Unlike the UK’s Prestel or West Germany’s BTX for which you had to spend …read more
