Ok, the instructions then :
http://dcmoto.free.fr/download/prog/dcmoto_201004.zip
File > Insert disc
Then press B or click the appropriate button.
The hardware is quite good for an 8-bit machine, but the bad-written system ROM pretty much kills it by preventing the use of interrupts (they are vectored in ROM).
This is mostly OK excet for sound, which is not plugged to a DMA so you have to send values to the DAC very often, and mix that with any other code.

Pulko: if you want to grab the prod and make a youtube version, you can contact me to get a special version of TEO that correctly emulates the interlaced videos of CRT.
A video is available here: http://www.serveur87.com/forumthomson/forum2010/presentations4.html. Note that the output on the video is not as nice as on a real machine due to the low quality of the video.
A note about technical aspects: Basically the video mode is 160x200 with 16 colors. In this mode it is possible to display more than 16 colors by changing the palette on each scanline. However, the CPU is so slow, that it can barely change 1 (or 2) color(s) for each line otherwise ugly artifacts appear. Therefore the palette-flip technique can only be applied on images with similar colors along consecutives lines. See http://www.pulsdemos.com/colorschina.html for further explanation (in french, sorry).
This time, the trick is different and there is no limit on changes in colors across lines. Actually, the trick used here allow up to 216 different virtual colors to appear on screen, making it possible to have almost true-color pictures on a plain TO8 machine.

Far out !

Thomson Demo, what could go wrong ?

if this prod is a fake, some info is false or the download link is broken,
do not post about it in the comments, it will get lost.
instead, click here !
I wonder when the fuck they finally understand that French isn't international language for hundreds years.
if you're interested in popularization the platform (pretty powerful btw, like it seems from descriptions) then you have to add instructions of loading and so on.
ah well, not my business.
