Oric RGB to CGA monitor
Oric RGB to CGA monitor
I just picked up a spanking brand new Goldstar 1410-CGA with RGBI.
It has a 9 pin "D" type connector.
1 Ground
2 Ground
3 Red
4 Green
5 Blue
6 Intensity
7 Reserved
8 Horizontal Sync
9 Vertical Sync
I hooked up a C-128 on it with no problems. Now, if I made the right cable, will the Oric RGB work with it?

The CPC monitor is a analogue monitor while the Goldstar 1410 CGA is a TTL (digital) so going to that discussion did not answer my question.waskol wrote:I would say yes : since it is possible to connect an Oric on an CPC monitor (have a look in the forum), the Oric and the CPC should have pretty much the same pinouts.

I think I explained it in such a way you did not understand.
A few days ago, I've asked on the forum if it was possible to use a CPC monitor with an Oric, and recently one answered me that it was straight compatible : Red on red, blue on blue, sync on sync... excet that there are 5 outputs on the Oric DIN and 6 on the CPC monitor (the central pin being useless with the Oric).
So if the outputs of the ORIC and of the Amstrad are so similar that they can use the same pins of the CPC monitor, I just guess that you will have almost the same hooks for the Oric as for the CPC for your Goldstar.
But I would add also that your monitor requires at least a line frequency of 31KHz, and that the RVB output of the Oric, like the one of the Amstrad or any other micro computer sends a 15KHz signal (PAL compatible).
sorry if if you misunderstood
The specs from the Goldstar owners manual are:-
H. Scan Freq. - 15.75 KHZ
v. Scan Freq (Which I believe you don't use with a oric) - 60Hz
I know I could hook up up a BBC B and a ZX Spectrum 128 to it no problem. I'll just have to make a straight rgb 5 pin din to a 9 pin d type with ground on 2 pins on the d type and Comp sync to Horizontal Sync.

If you did it with the BBC, the spectrum, and the CPC, it will be the same with your Oric.
