Re: Merging video output?

Please find below an idea to test... with a NAND gate and an input to Vcc to replace a NOT gate --> Only needs 2 packages DIL14. The 3 last gates delays (3x10ns) the clk, to try to have a better synchro. between the clks (perhaps it is better with less or more gates...). I do not know if it works, n...

Re: Merging video output?

8) This is the kind of simple circuit I thought, to avoid something complicated like a complete PID controller. I will study the practical application on real Orics. But in your opinion is it possible to simplify again? (eg if you remove the LS04 between the 86 and the NAND, and replace the NAND by ...

Re: Merging video output?

@iss: nice work! - Thierry suggest to keep a common 12mhz clock, and just to throttle the secondary ULA until it get synced to the first one On my side I am looking for a simple schematic to do that; Below some links to clarify what I am looking for (in the electronic world): French: https://fr.wiki...

Re: Merging video output?

Yep, I missed that offsets are multiple of 83.3ns. Mike Brown's solutions is cool and I hope it will work. ... but having 2 equal ULA's is good idea too ;). EDIT: Dbug, which signals are actually on the scope? (I thought it's 12MHz, but the shape reminds the famous F2) Good question! Yes this is th...

... you need to use the right firmware, else the display stops working :)
My Cumulus (PCB ID #43) has a black dot on the PCB above the 3 buttons, so a S1D15G10 display.

If there is a new update of the firmware, I can try it too!

Re: FloppyBuilder evolution

But I'd try to produce a version of the game which simply bypasses the bug, because not everyone is going to update their firmware... And, besides, who would do it? :wink: The Cumulus firmware update seems easy to do? www.youtube.com/watch?v=WoVpMwnYQIY Is there a link for dowloading the latest upd...

Re: How to install a 3" floppy drive on a modern pc?

I have a HxC (drive A) and real drives (B, C) to generate real floppy discs (3 or 3,5 inches)
On PC (Win7), convert .dsk to .hfe, then copy hfe to SD card.
On real Oric boot on hfe then backup...

STRATSED

What is the last release of STRATSED (DOS for TELESTRAT)? There are STRATSED2.0a, STRATSED2.0b, STRATSED2.0ca. I saw somewhere in the forum (but I do not remember exactly where), a picture of a screen boot with 'STRATSED2.0E'. I will upload that picture here when I find it. Found on oric.org (Forum ...

Re: Next Cumulus batch

Are you still interested in an Atmos that won't work with Cumulus? (I sent you a message but got no reply. ) I had my monitor repaired and found an Atmos that boots but won't works with the old ULA or a NEW one. (With my other Armoses the Cumulus worked with a new ULA). Oops sorry, completely forgo...
