Faulty Microdisc?

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.

That's true but... Is the Phi2 output an open-drain output? (the 6502 is a N-MOS device) :wink: . Looking at Oric schematic i think no.

From "Réalisez un contrôleur de disquettes pour votre Oric (type Microdisc) Par Thierry Bestel (partie 2 / 3)"

"J'ai relevé sur cette carte les chronogrammes diffusés sur la disquette trimestrielle du MAG de mars 2002. Ces chronogrammes sont une aide précieuse pour vérifier et comprendre certains signaux critiques de la carte contrôleur."


Has nobody the mentioned one disquette with the chronograms? :(
