Re: And now, box for the controller.

Nice !
Maybe that could be done for the Oric computer and the Atmostrat project.

...Also ,somebody know why in Cumulus is Flash EEprom 256, not normal eprom like 27c64 ? Rom for microdisc is 8 KB. So what about rest?
It's more handy for updating, you don't need to erase the software with an UV lamp to re-write. I suppose that the EEPROM contains also the update microprogram.

Re: Transformer/ power supply

I am not agree with you Godzil, indeed, we can use a rectifier for each regulator, that will make a schematic respectful of electronic theory, but sometimes, when the manufacturers want to make a low cost device, they use the middle point of the transformer, who is not oscillating despite the appear...

Re: Transformer/ power supply

As I can see on the picture the transformer is a classic one with two coils connected in serial mode and the output is in the same configuration, the middle output connection is used for a symetric rectifier, then I suppose that the transformer gives the same voltage in the output (for ex 2x 9v).......

Re: Transformer/ power supply

Maybe a component of the interface that spends too much energy ?
You can check it by touching the heating surface of the component.

Re: Transformer/ power supply

3,8v in place of 5v it is too low. At least we need around 4.8v.

Re: Transformer/ power supply

You can disconnect the 2200uf condenser and check that the 12V regulator is switched on again, we can verify if the chemical condenser is too old. Very important: when the load is connected to the regulators, the cooler is required, (the metal plate screwed behind the regulator with the sticky therm...

Re: Transformer/ power supply

It will be intresting to know where the voltage is down, an electric shock may destroy the varistance, a fuse-componant, or the input coil, you can test the last one with an ohmmeter with the power off, switch on, and test the output coil with a voltmeter, and finally the output regulator voltage. I...

Hello everyone, I finished the experimental SDcard reader, in the video below, I show the way to find the place where the game is stored in the MicroSD, with a BASIC program. It is not yet subtitled. http://www.dailymotion.com/video/x57qwr4_lecteur-de-carte-microsd-erebus-pour-oric_tech Later, I'll ...

I was very impressed by the double screen demo of the AtmoStrat at the Vieumikro meeting this last weekend in the south of France. Nice project ! :wink:

Re: Not another boulder dash clone!

I ve just tried the game, it is beautiful but hard to play, I knew that a rock on another one could falling but not a rock on a wall. :oops: :D However this game is the first genuine version for Oric, at last ! Thanks Seb :wink:
