The slot is the wide version, so you have to put two in at once and format them as double density.

...and most modern websites seem to me to be triumphs of design over content, all very pretty and full of marketing but really hard to navigate and find information on :-(

E-Mail before the Internet YouTube video by RetroBytes

I made a video, as I occasionally do. This one is about the world of email before we all started using Internet email, in particular company group mail.

We're going to do it all over again! Very excited to announce RetroFest 2026 to be held at Swindon's STEAM museum on the 30th/31st May. If you'd like to exhibit, just full in the form - and if you'd like to come, why not buy a ticket! They also make wonderful Christmas presents :) - retrofest.uk

I remember single `pop` 45rpm records being 6 shiilings and 8 pence .... IE: Exactly 3 to the Β£1.... Can't do 1/3 of Β£ in decimal.

Here’s my (later than sort of planned) video on the Retrofest event held in Swindon/organised by @shortcircuit.org.uk

Follow me as I take some janky video footage of old tech πŸ˜… and marvel at this great event and exhibitors.

He may not be a Red Arrow but John does make exceedingly good videos. This one on the OSI Superboard II & UK101 is well worth a watch.

Big heads up to the team at Retrofest 2025 at Steam in Swindon last weekend. Amazing show of old computing and electronics. Next year is going to be epic! This is me with my rather simple setup playing Quake on Dual 3Dfx Voodoo 2.

RetroFest June 2025 YouTube video by Break Into Program

In between talking to folk at my table about the Tatung development system, I managed to grab a few minutes to walk around and see what my fellow exhibitors were up to. Apologies for the sound - shot live on iPhone, and it was very noisy in the hall.

Well, the only way you could have made more convenient for us would have been to hold it in Newbury :-)
... Thanks again to you, Tony and your helpers for a trmendous event !

You need to get yourself a RC2014 Mini 2 Picasso. Lovely Z80 based goodness.

Great time at Retrofest 2025 at the STEAM museum in Swindon UK this weekend. Surprisingly our trains-being-driven-by-old-computers setup kept going OK, so the Replacement Bus driver spent most of the time relaxing in a little hut :-)

Not quite enough table space for a VAX 11/780, so i had to make one out of LEGO ... It's not much more intelligent than my BBC Micro, but it does run the classic `Adventure` game :-)

This old torch add-on is the one with a 68000 board and 20mb drive for providing a unix 2nd processor on a Beeb - appropraitely called a `Unicorn`

It's only FOUR WEEKS to go until RetroFest. Our exhibitors are slaving away to get their machines ready - and what better way to test them than displaying our logo! Tickets are selling fast, so we recommend buy one in advance if you can - www.retrofest.uk/tickets.php

I am clearly incapable of spelling `incapable` :-) ...
Plus, I should add that no LEGO was harmed during the making of this item.

Mainly for writing code for the brother's genuine 77-68s I tend to use a more modern device simulating the old iron, mostly because I am incapale of maintaining the real thing :-) ...
Here is what I use for 77-68 code testing - A LEGO Newbear 77-68... The mess inside is based on an Arduino DUE.
