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.
@HigashiJun, @Symoon: What models are your 15 kHz compatible VGA monitors?
Oric outputs the CSYNC signal as negative pulses - are the Sync Striker output HSYNC/VSYNC compatible with the monitor requirements?
Else thanks to this thread, I recall that I should have some old VGA monitors buried somewhere in the attic and today I found them.
Both are 17" - a Philips 170C and an Acer AL1714. Unfortunately they don't support 15 kHz ., but I decided to make them usable with Oric.
I used a cheap AV2VGA converter slightly modified:
... and mounted in place of the UHF modulator:
Here is the result:
The colors are awful but black/white pictures or texts are stable absolutely acceptable!
I'm using this Oric board for tests with the tape I/O so I'm happy with the result and the old monitors will have new life.
About the AV2VGA converter: Honestly I can't recommended it. It's cheap (~4$) and the quality of the board and the soldering is ... low like the price
The biggest problem is that the chip AV775C gets very hot - to fix this you need to apply some solder at the bottom side - there is a big pad which purpose is exactly to be like heat-sink .
The test program is attached, it draws on screen and then waaaaits, so be patient.

Hello iss,
My monitor is a NEC Multisync LCD 1990FXp.
There is no much information about the Sync Strike, even on the Arcade Forge website, but as nothing is said about monitor compatibility, its should be OK.
I had no time to try the device with my Amstrad CPC6128 nor my AMIGA and ATARI. I should have some time next week to check everything.
NEC Multisync LCD 1990FXp - Manual HERE on page 16:

Sorry for the bad news but this monitor is NOT 15 kHz compatible .
Do not worry, it is 15 kHz compatible...
I know the manual does not mention it (like all other MultiSync monitors), but my Atari STE is connected to it and I have low-res and hi-res mods without a glitch.
My monitor is a DELL P2214H.
Works great with Atari STs, and with some (not all apparently) DB23 => VGA converters for Amiga (one of the two I got sends the monitor to sleep mode, haven't had time to search if it is a known issue).
