Although simple, the PAL encoder in Oric-1 was fully digital.
In fact, a 8.8672375 MHz oscillator (which is 2 times the color carrier frequency in PAL = 2 × 4.43361875 MHz ) along with R,G,B and the Sync signals generated by ULA control the address of the PROM (a 256x4 ) applied to a resistor network making a simple DAC. This signal is then applied to the RF modulator:
I know that since RGB and Sync are applied to another output port on Oric-1, a SCART(Péritel) could be used in France but since not all TVs were equipped with a SCART this could have limited its market in France.
Since SECAM uses a frequency modulation to code colors, a SECAM digital encoder was impossible to make at the time.
Was there any other options (like integrated analog encoder) for SECAM on some Oric-1 intended for France?
