Re: OricExos - making the impossible

OricExos-preview.jpg OricExos with extensions, PAL encoder board and cumulus - everything works! As you can see the PAL encoder board has Composite, S-Video and RGB outputs. The signal amplitude from the RGB output is bit low, so I have to add an extra video amplifier - AD8013. This was the last ch...

Re: Microdisc connectors

Nice info about Telestrat and Microdisc connectors:
A la Decouverte du Telestrat.pdf (with subscription) and DES DRIVES POUR VOTRE ORIC.
Here is the summary:

I've rotated the connectors on the right to match the left picture.
So, the hand-written notes on your pictures are confirmed. :)

Re: Novalight - very fast tape loading

I'm still not familiar with the Novalight code - it's complex and requires lot concentration. But this 7 bytes should be needed only if the next part starts with the standard header, right? I'm not sure but maybe it makes sense to have a kind of synchronization between parts... and 7 bytes are not s...

Re: Oric-1 Sound Mod HELP !

Check the cable from RCA to the 1084 monitor, check the switch on the 1084's back (if any) - is it in correct position? Check again if the switch makes good connection in both positions - measure the resistance between the middle pin and the other two. BTW, check the resistance between the left and ...

Re: Novalight - very fast tape loading

Great piece of software, Symoon, I really can't imagine how many time and effort you put in Novalight but it's worth! Chapeau bas! ;) The source compiles fine under Linux with GCC (just 2-3 harmless warning - no problem at all) and the tool works nice. I spotted just one thing which seams like bug: ...

Re: Novalight - very fast tape loading

Absolutely incredible work! Congratulation, Symoon!
Thanks for all your effort in pushing CLOAD to the limits.
Releasing sources and the well documented details makes Novalight huge event in this small Oric world!

Re: Help with a "Your computer" program

Nice article! Unfortunately the bad scan quality is not the only problem :? You can see in lines 170 and 800 the '!'-vector is pointed to address 40396 i.e. 170 DOKE #2F5,40396 but 40396 = #9DCC and this is jump in the middle of instruction: $9DCB 85 A7 STA $A7 I think the correct entry point should...

Re: TapOric - android TAP player for Oric

A short story with happy-end from today: The main reason to delay TapOric's first release was actually the fact that I've had problems to make it work with one particular device: Asus Zenphone 4. I made hundreds tests but loading always failed with errors. Last week I started again to try to fix the...

Re: TapOric - android TAP player for Oric

@Symoon : It would be great to include Novalight in next version. You can PM me the source and don't worry about its style :). @Chema : Yes, I'm using the latest sources with your change (#99->#96) included. Actually I made new precise (I think) measurements and corrected all timing to bit lower va...

Re: Oric-1 RGB to SCART - pin 8?

It would be very easy to diagnose the problem if you have an oscilloscope ... ;) IMO are 2 possibilities: - missing Sync signal - check everything again, follow the tracks on PCB, are all chip pins well inserted in the socked, check the transistor responsible for the Sync signal. - bad Sync signal l...

Re: TapOric - android TAP player for Oric

Cool! I'm glad to know that TapOric works on Samsung Galaxy S9+ ! It will be very useful to share the model of devices on which the app is tested for a (in)compatibility list. About the cable: in short, here the point is more to satisfy the phone requirements then the Oric. Ideal is 4-pole 3.5mm jac...

Thanks for all replays and for the nice words - I'm happy you like TapOric ! Here some answers: @coco.oric : about the android market - no plans for now. If the point is to have automatic check for updates only, I can add this option based on my own solution. @Jack_Free : the slow mode is really slo...

Do you have these changes publicly available somewhere? ...

Makefiles to compile the OSDK sources from DF SVN reposi...

1. Are the colors of the wires as on picture?
2. Check if the switch makes good connection in both positions
3. Take new picture with the RCA socket and the switch included....
