oric sur moniteur RVB ?
Bonjour à tous,
Pourrait-on brancher l'ORIC sur un moniteur TFT RGB du type utilisé pour une camera de recul sur voiture ou pour visualiser de la video et que l'on trouve à foison sur ebay... (cf. photo). Existe en 7 et 9 pouces, pour des resolutions debutant à 480 x 234 pixels...
Merci pour vos réponses et mes excuses si j'ai envisagé une ânerie..

Re: oric sur moniteur RVB ?
Good question, I guess it depends of the type of supported inputs.
The screen I have on my car for the rear view camera supports only composite signal, so that would not work on the Oric without some converter, but internally they probably all get converted to RGB, so I would not be surprised if some of these screens can get direct RGB input.
Need more details about the screen

Re: oric sur moniteur RVB ?
Most probably your device has only AV-input - this is CVBS or as Dbug already said input for composite video signal.
You can use external RGB to Composite converter (simply search e-bay), relatively not cheap solution but it works.
Else, if you like hardware hacking, there are 2 possibilities (atleast ):
- open your Oric and get composite signal before the UHF modulator, additionally you need simple 1 transistor inverter-amplifier to adjust signal level - this worked for me - I use portable 7-inch DVD player with the same resolution 480 x 234 pixels.
- hack your device - theoretically there is chance to connect RGB+Synchro signals from Oric directly (or with few resistors) to somewhere on the TV's PCB. For this you will need the service manual and data-sheets for your device.
If there is interest I can post the "know-how" how to convert broken 7-inch DVD player for 3EUR into portable monitor with Composite, S-Video and RGB inputs.

Yes, it's a good idea.If there is interest I can post the "know-how" how to convert broken 7-inch DVD player for 3EUR into portable monitor with Composite, S-Video and RGB inputs.
If it's not too difficult, i'm interesting in it. It will allow me to go to the ceo visu with a smaller bag.

Re: oric sur moniteur RVB ?
N'ayant pas encore acheté ce petit moniteur, je n'ai pas vraiment de détails sur ses possibilités techniques. Pour le modèle dont la photo est jointe, voici les précisions données sur e-bay (http://www.ebay.fr/itm/Moniteur-TFT-LCD ... 2a40b8b600 - adresse de commande en Alsace... vendu 60 €):
Description: Moniteur LCD 7 pour voiture
Système vidéo: PAL/NTSC
Chip: UP CMOS
Résolution: 800 x 480
Angle de vue: 130
Luminosité: 400cd/m²
Contraste: 350:1
Alimentation: DC12V
Connectique: Double port vidéo
Fonctions: Menu OSD, système rétroviseur, AV (CD, VCD, DVD, GPS, caméra)
Dimensions: 194 x 142 x 30 (mm)
Poids: 392g
Il semble n'y avoir qu'une entrée AV... Un schéma pour éventuellement adapter le signal de l'Oric m'intéresse beaucoup !

Re: oric sur moniteur RVB ?
While there are a lot of French people around here (who said too many ) you'd better write in English to get more answers
Anyway, as coco.oric said, your Oric modification details would be very interesting iss.

Hello iss,
I am very interested by your solution to convert broken 7-inch Portable DVD Player Into monitor with Composite, S-Video and RGB inputs.

Re: oric sur moniteur RVB ?
Here are the pictures.
This is my Pravetz with 7-inch LCD from broken portable DVD player.
(The UHF modulator is removed since long time ago, of course you can leave it as is). Output signals: white = GND, red = 5V, green = composite video This simple 1 transistor inverter adjusts signal level to match the AV input. (I'll post the 'schematic')

Re: oric sur moniteur RVB ?
Here are 'schematics'.
This is part of the well-known Oric schematic showing where to get AV signal: And this is the one-transistor stage: As you can see in first picture I removed R15 and RV1. They can remain, but than R0* (in second picture) should be used.
As conclusion I can say that the quality is not 'the best' but it's fully acceptable.
Some scanlines are missing, so text is bit hard to read, but in general for demo purposes and 'mobile gaming' is OK!

Re: oric sur moniteur RVB ?
So whats next - a decent battery-based power supply that'll drive a Cumulus as well, all packed into a nice little briefcase?

Re: oric sur moniteur RVB ?
A portable Oric would be nice indeed.
Fabrice made one with a four line screen IIRC but it would be way better with this kind of screen.

Re: oric sur moniteur RVB ?
What would be nice is to have an hybrid Cumulus with a larger screen, with at least 240x224 resolution, and have the screen used both for the Cumulus UI and the Oric video output
