Kenneth, can you provide location in ROM to fix it?
In the Erebus file the Oric Rom code begins at the same place as the Basic11b Rom file, then you must replace these bytes:
Adr $3934:
#1E before, #1C after.

Adr $39CA:
#1A before, #18 after.

Re: Need help fixing Oric 1

Normally the chips have supports, I designed the pcb to install a ZIF support for those who want to program the Uvprom.

Re: IJK interface diagrams.

Are there the 4 bridges on the top of the pcb?
Maybe a chip or the diode mounted upside down?

Re: Need help fixing Oric 1

The computer uses the 50Hz frequency for the screen, the POKE will set the ULA ship in the 60Hz mode video for US country, in the HIRES mode,I suppose that the routine will switch the ULA in the 50Hz mode because of random poxels. You must burn an Uvprom with a little code to switch the both resolut...

Re: CEO Summer Meeting in June

Very interesting, for me it was midday, I had to slip away during the demo of JeDe (I apologize to him, the meetingmaster and the other guests) the hp and the microphone were deactivated and reactivated just in time . I can't wait to see the entire YouTube version.. 8)

I m agree with Chema, the RF output with the aerial cable is the best way to check your Oric.
NB: With Erebus, your Oric-1 will become an Atmos.
Kenneth,
What do you mean by "With Erebus, your Oric-1 will become an Atmos"? Does the erebus replaces the ROM on board the ORIC ?
Exactly :wink:

I don't have a Microdisc.
If I could see where is the joystick code into the Blake's7 file I will verify.

Re: IJK-egoist new joystick interface by [raxiss]

The connector of the Sega joypad is hard to connect, I think the HE10 connector of the printer port will have to be connected last and then disconnected first.
