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.
Fabrice would ofcourse be the best person to ask.
Since i never owned a Telestrat i'm not the best person to ask
Thierry Bestel will know but i don't have his email address.
You might ask Symoon (he should have Thierry's email) and if he doesn't know he should point u to someone who does.
