What happened to ObsoNET?
Dhau, I was in touch with Daniel who build the Obsonet and he wrote :
many years ago i lost all the schematics when i formatted my hard disk by mistake 
so i have not the schematics or gal binary.
Hello Fred,
I tryed many times to redo all the job, but had not patience.
Anyway, i have many useful information like a datasheet for the mapper, is not the original GAL16V8 mapper, but is an equivalent designed with discrete logic (74HC133, 74HC138 and many diodes).
Maybe you could substitute the gal part wiring the 74HC138 and many diodes in the datasheet way....
So I guess we need to find one , an reverse engineer it, like scan the pcb after removing all component and use the inverse VCC approach to dump the gal ...
next step is to find a color security monitor to get a sample to play with 
@Morg:
You moron, your Obsonet was a GIFT for you after you insisted you wanted one, and now you are trying to trade it for anything else??
You don't deserve Kyoko's food anymore.
Para duplicar obsonet, tendriais que copiar a ojo todas las pistas de las dos caras, trabajo que no es poco, para despues poder colocar los componentes. Luego los acidos y toda la parafernalia que tiene despues.
Para ello existen programas como muchos sabreis, pero en mi humilde opinion el trabajo solo compensa como desafio propio, ya que estando Denyonet tan cerca...
Es cierto fue formateando con linux borro los archivos...
To duplicate ObsoNET, eye you would have to copy all tracks from both sides, work that is not enough, to then be able to place the components. After acid and all the paraphernalia that is later.
For this there are programs like many of you know, but in my humble opinion only compensates work as a challenge itself, since being so close ... Denyonet
It was formatted with a linux delete files ...
