#agonlight — Public Fediverse posts

Retroparty war wieder genial ❤️
Da wir an die Kapazitätsgrenze geraten, wird die nächste wohl an einer anderen Location stattfinden. Dieses mal stand die Party unter dem Motto Atari. Ich hoffe ein paar Amiganer konnten Vorurteile abbauen, ich schon 😉

Der AgonLight ist kein Raspberry Pi, sondern ein echter 8-Bit-Computer mit „Bare-Metal“-Design. Er kombiniert eine 50 MHz eZ80-CPU von Zilog mit einem ESP32 als Grafik- und Sound-Co-Prozessor.
Bootet in Millisekunden direkt in BBC BASIC. Wer Technik ohne Abstraktions-Layer verstehen will, bekommt hier direkten Zugriff auf CPU, Speicher und Register.

Time for another image viewer for #AgonLight #Console8 - this time, PCX format. There are a number of reasons why I chose to display this format on the Agon/Console8.
* It is an already existing format
* The format is supported by modern tools, including #GIMP
* It uses a very simple form of compression ideal for 8 bit CPUs
* The specific choice of 16 colours has additional benefits:
* The 16 colours are chosen from within the available 64 colour palette
* The 16 colours allows the image to be sent to the VDP with 2 pixels per byte, speeding up the transfer
I've attached a sample here to show just the quality of the resolution and colour depth. #z80 source code and binary is at:

I recently took advantage of some temporary discounts and acquired the #Console8 by Heber. It's a #retrogame focused package of the #AgonLight, complete with some great joypads that they also make. As part of the induction into the house, I converted the logo into something a little more 8-bit, and updated my logo software. #z80 #ez80 #retrocomputing

I wanted to use more graphics on my #AgonLight and the best project that came to mind was to display #Amstrad #CPC .pal/.scr images. Took a while to get there, and now it works including the same "wipe" effect that the original hardware had due to the unusual RAM layout. Planning to use this for landing pages to create the mood for any game you might load. You can see the source code + binary at https://github.com/sijnstra/agon-projects/tree/main/CPCpic #z80 #ez80 #retrocomputing #retrogaming video shows loader image from Stefan Vogt's Ghosts of Blackwood Manor.

Working on making my telnet for #AgonLight more sane, it's a little better than it was but still has a lot of problems. It's hard to test something when the results depend on the network traffic flow at the time, and many components out of my control. Anyway, for a first time I did manage to get some almost readable data from @Wintermute_BBS RC BBS - thanks for having this running! It feels awesome having an #ez80 talking to a #z80 on the other side of the world!

Collaborating with TurBoss on this one - I can now telnet from my #AgonLight via the @olimex UEXT wifi module and straight across the internet to an #IRC server, which in turn has a bridge to Discord. That's right, we can talk Agon to PC or even Agon to Agon via IRC/Discord. #Discord and #Agon shots below. #retrocomputing

I've improved the #AgonLight implementation of Daniel Martin's #TRS-OS to make a more authentic #trs80 experience. The main thing I wanted to improve was the display capabilities. Steps taken (with thanks) to get the authentic output:
1. Obtain + fix the correct font
2. Load the font into #Agon
3. Modify the VDP to allow buffered fonts in Terminal mode
4. Modify the bootstrap and terminal host software to support the new code and use all 8 bits.
5. Check out before and after
#retrocomputing

Using the character to bitmap mapping available in the latest #AgonLight VDP firmware, I've been able to transform an ASCII #curses version of Flappy Bird into graphics. Double-buffering ensures the game plays flicker-free. Before and after images included.

Got my Agon Light 2 computer recently and installed CP/M on it (https://github.com/julian-rose/Agon-CPM2.2/tree/playpen). Great little machine, I am surprised how fast it is.
It self-compiles #T3X 16 times faster than a 4MHz Z80 (and clock speed is "only" 5 times faster). It even runs Evazor smoothly! I have added a CP/M binary to the Evazor archive in case you want to try it.

@sijnstra thank you for creating and maintaining #vezza. I use it to play games on my #rc2014 and love it. An #AgonLight version would be cool!

The next stage of developing my #Infocom #text-adventure player #Vezza, I'm making it Agon VDP native to take advantage of the new features in the #Console8 VDP development line. Still a work in progress, but the vast majority seems good to go. Why do it? I wanted to play Beyond Zork on the #AgonLight using the extra font features. This means instead of text drawing of maps, you get something a little more graphical. Also, status bars are now drawn for more visual impact. #retrocomputing
