This is pretty cool.
It's a visualisation of the internals of The Sentinel on the #BBCMicro.
This is it generating the game landscape for the first level from 1024 pseudo-random numbers.
Next week I'll be releasing a deep dive into exactly how this works.
***
A big thanks to Simon Owen, whose excellent repository I forked and enhanced in order to build this visualisation. It's well worth a visit.

I’m back into retro coding business tonight! i just launched my x16 commander computer (yes I have a real one) and coded a tiled scrolling background layer with some checkerboard and front layer with regular text scroller. Very damn #c64 alike style.
Not perfect as font is ugly as shit but works and it’s smooth and I continue having fun with 8-bit assembly.
Tommorow if I find time I’ll try to make font nicer, more Amiga style scroller and then I’ll publish it as bbstro maybe, or sth..
Fun… first graphics orientated project since autumn when I parked my retro 3D project somewhere in the middle of completing.
I consider tonight as a drill to come back to the latter

Perhaps the other surprise omission from the FrontierAstro Top 5 Elites was the #ZXSpectrum version. A lot of people loved this back in the day, but to me it looked drab and ran too slowly. Somehow it lacked the magic of #BBCElite and was inferior to the #C64 version too. Sorry!

My #C64Ultimate arrived at 10pm last night and the first thing I did today was to build my first levels in Wizard in 35+ years. It is actually a passable level. On the fourth try.
Level name: "Distract-A-Rat"

RE: https://mastodon.social/@samster/116093908713088888
(1/2) Thanks for the mention Samster. My journey with SID and the Z80 started way, way back in 2002, working out how to get it to play happily when connected to a fast Zilog Z80 bus on the SAM Coupe, rather than the MOS6510 it was designed for.
2003 saw the first commercial version of my SID Interface for the SAM Coupe. It's had a few tweaks in the years since and is still available.
In 2020 I was asked if the interface would work on the RC2014 (Thanks Shiela!). Replied no, but then a few weeks later, yes!, having redesigned the interface in a version specifically for the RC2014 bus and integrating an interrupt controller for 50/60/100Hz - ideal for use with other soundchips too! This version has also had a few tweaks over the last six years since release, currently on v1.3.
Can't add photos due to the 'quote' so will add a reply to this post with photos... (Nice to see this now implemented in Mastodon!)

I've started writing a series of deep dives into Geoff Crammond's epic #BBCMicro game The Sentinel.
Here's the to-do list.
I will post a link here whenever I add a new one to https://thesentinel.bbcelite.com/
It's going to take a while! But it should be worth it...

Weiß zufällig jemand von euch, für was genau dieser Anschluss an der Front der Platine (unter den Tasten) der #C64 Datasette ist? Bei geschlossenem Gehäuse ist dieser weder sichtbar, noch zugänglich (weil hinterm Gehäuse).
Wirkt irgendwie so, als könnte man da eine Datasette (?) anschließen.
