oric broken tv-out and rgb output
Paul Woodward
parents house. Although I have a tape connector and power supply, the
original tv lead was missing.
I have tried connecting to the composite in connector of my TV, but with
no luck. I suspect the TV-out on the oric is be defective.
If so, does anyone know if/how the TV out could be repaired?
Alternatively, there is the RGB output. I understand (oric)RBG to SCART
(TV) is possible, but making the lead is not easy. My soldering skills
are poor, and I don't have resistors etc lying around the place. Is it
any easier to make a RGB to VGA monitor cable? An idiots guide to making
either of these cables would be appreciated.
I assume there were terminals around 20 years ago which would easily work
with the oric RGB - do we know which ones, and are these available anywhere?
Paul.

Well, it had crossed my mind. I was hoping to get it working, partly for old
times sake, and partly at least I could pass it on knowing it was in
working order.
I was also wanting to play Snowball Adventure, but I've since got hold of
euphoric from the oric.org ftp site, and have just spent an hour playing
the game - brings back memories! (I'm still stuck btw.)
I'd love to play with it, but I don't really have the time or money to
spend on it at present. So I might be interested in selling it if it will
go to a good home...
Paul.
P.S. do you know if the TV out should work on the composite in on a modern
TV? I assume it should work OK, but I don't really know...

Just a thing, are you talking about a REAL composite input on your TV ?
Because Oric doesn't has composite output, the output I think you are
thinking about is UHF output, so it is plugged on the antenna input of
the TV.

Here is a simple RGB to SCART cable setup for free :-D
RGB = Oric manual : to
SCART:
1 red to
15
2 green to
11
3 blue to
7
4 sync to
20
5 gnd to
13,9,5,17 (together)
Hope you can make some sense out of this.
I have made several cables like this, and all you need is 1 SCART cable and
1 DIN plug.
The picture is crystal clear and steady as a rock!
No need for resistors or transistors or extra power suplies.
Have fun now ;-D

I had a diagram like this on my website and I was emailed by more than one
person who said this wouldn't work and could damage some televisions. The
best available circuit is the one provided on DBug's site - or so I was told
!!!

You can easily make one with a piece of coaxial cable and a TV aerial plug
at one and a phono plug at the other.

It may well be tuned in wrongly. I've found even if Orics are tuned in right
you still might not get a picture if the settings underneath are not
adjusted properly. It is probable that after this time you need to set it
all up again.

If it's just the modulator I'd simply swap it. It just takes a bit of
soldering.

Any RGB monitor should work OK if you know trh epin connections - Microvitic
Cub etc. I use an Tatung Einstein Monitor and a Amstrad CPC one too.

Thanks for the input. The link you point me to is the one I had
previously found, and it scares me. I don't really fully understand the
diagram, but it looks like a fairly complex job to me.
Does anyone (DBug?) have an idiots guide to making such a cable, e.g. bill
of materials, required tools, idiot proof diagram or pictures??
Anyhow, it appears my plugging the oric into the TV composite-in was dumb
anyway, so I will make a suitable coax cable, and see how that works.
Paul.

work! :)
I will make up a proper cable and plug it into the TV correctly. Thanks
for your help,
Paul.

Hey, it's not a TV composite output that you have on the Oric, it's an UHF
modulator !
You can connect it to your TV antenna input, and search around canal 36.
But of course the image will be as good as the one of a Sinclair Spectrum,
so I won't recommend it : build a SCART cable and you will have a
cristal-clear image !
Best regards,
Fabrice

It also scares me, and I don't understand it myself :)

That page only reference a schematics that was discussed here few years ago,
and I only put it online so everybody can access it.

This cable diagram is not the same you had Steve.
I can't guarantee anything, but this is the setup I use myself both on my tv
and on my monitor witch has scart input.
It shure works for me without any problems.

Mmm, it is slightly different. I think it is still online
www.48katmos.freeuk.com/scart.gif
I never really understoof why pins 16 and 19 were connected in this diagram.
The only other difference is the ground is connected to pin 21 - probably a
screen (?)

"Pin" 21 on a SCART connector is the outer shield - have a look at one and
you'll see what I mean.

Can't ! - all the SCARTs I have are sealed ones on cables. I use moitors for
the Oric so I've never needed to make up cable to SCART on the TV.
I was told that not all UK SCARTs had all the connections and some used to
have just a dummy socket with no connections inside ! They do seem to vary
somewhat.
I think the best option is to find a monitor adn stick the Oric oout of the
way of the telly - then the wife won't see it and complain about all the
computer stuff you are accumulating !

I meant, look from the pins side: you'll see two rows of ten pins, staggered,
and the outer metal shell goes where pin 21 would be. This is going from
memory - there may be more than 20 ("21") pins - but there certainly is this
principle.
