I've rewritten my #Console8 logo player -also works on #AgonLight - and updated the video file for 2 reasons. 1. it was a bit long playing the whole thing, and 2. I wanted to play a higher resolution video, covering as much of the screen as possible. With a bit of video editing (cutting and cropping to make the most of the logo at the end), plus taking advantage of the VDP code for both decompression and bitmap expansion, this is what my boot sequence looks like. I've left the logo to linger a little, but that's optional and a quick change to the script.

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

Initial release of https://github.com/triplefox/agon-vdptypes

VDPTypes is a Python library that assists in generating VDU protocol data for the Agon computing platform's VDP (Visual Display Processor). It supports Console8 as of version 2.12.0, minus some experimental API calls. Not all calls have yet been tested.

Contributions are appreciated, my bandwidth to work on Agon projects is limited.

VDPTypes is a support library made for customized build scripts, asset conversion, and development of VDP buffer programs. It includes:

* Utility code for loading and converting assets to VDP formats
* VDP-IL, an intermediate language for VDU commands using Python data structures, giving them some syntax and automatic checking
* Code generation for several language targets on Agon (unfinished)

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

While I'm far more partial to the design of the #CommanderX16, I must admit that I am a bit excited by any sort new retro-computing, retro console device.

With that in mind, allow me to present to you, this video on the #Agon #Console8:
