Re: VIA "networking"

The VIA chip is very useful in many protocols in the serial mode, but the used channels are CB1 CB2, unavailable on the printer port, in spite of this, we can connect all Orics on the parralel bus, and connect a little EPROM interface on the expansion port like Fabrice-F PCB with an 'almost' same BA...

Re: ORIC SDCARD

nice project :D
The +5v is also available on the main power socket of the Oric computer.
The relative voltage from the Oric ground is -4v and +5v (negative regulator).

Re: Speech Synthesizer for Oric?

I think that there is no power enought on the printer port and IJK-PASE interfaces are not compatible.

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.
