If you want to ask questions about how the machine works, peculiar details, the differences between models, here it is !
How to program the oric hardware (VIA, FDC, ...) is also welcome.

The ULA I think is the most difficult part. There were some units for sale on eBay recently

You don't need this small ROM unless you use the RF out.

Wrong this prom is to mix the rgb signal from ULA and send a composite+sync pal signal to rf modul.

That's exactly what I said. No need for this ROM until you use the RF output or if you are not using RF output, this ROM is useless.

Ok maybe i write it wrong, the rf module need the tbp24s10n to work and send picture on tv, you can see it on schematic diagram.

Yes, but nobody use the RF output nowadays. The RGB is clearly better and easier to use on modern TV/Monitor than the RF output that won't even work with DTV.

All the CHIP releated to the RF module are not necessary to make an Oric working. (And there is a lots of component that can be removed)

Ok i understand what you say BUT, i need to use that ic because is encoding the rgb signal from ULA an converting to Pal composite. If i dont find someone to write it for me i will try to use a GAL.

do you actually need PAL?

because a lot of people just use a pc monitor and one of these.
