... 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...

Video output without SCART/RGB

Hi,

end of 2014, manufacturers will no longer have to integrate in their devices SCART ...

What will be the best video output for our ORIC from RGB?

Is it possible to build a small interface without having to buy an expensive converter?

Maybe? With the 'probe jig', and the demo file 'PushingTheEnvelope', when I remove the probe, the system is working some seconds (about 2 to 5) then crash.

Re: Cumulus Issues

This is clearly not a good sign, may mean there is a ground fault somewhere. You should do a ground check to verify that there is no too high resistance between two (or more) ground point. Does it do the same if you touch pin 2 (Data In) (Pin 14 is Data Out) Faulty DRAM with probe alone (1Mohm||18p...

Re: Cumulus Issues

Only chance? I do not think so, because IC12 is D7 (bit 7), and D7 is a little bit special on Microdisc. This line can be driven, and maybe the Cumulus is 'more severe' than Microdisc (Cumulus schematic quickly examined but did not saw a specific problem). So, could it be a problem with timings in ...

Re: Cumulus Issues

About DRAM, I can tell you that, my rams were changed few years ago. Maybe that is the problem.. Hi, found a very interesting thing tonight. Perhaps it can solve your problem. My third unit is fixed: cumulus_compatibility_update3.png Yet another DRAM changed, but I noticed on the 2 previous repairs...

Re: Cumulus Issues

This DRAM thing is quite interesting... Maybe at least we found one source of problems? are the specs of those DRAMs different from original Oric RAM chips? What are these specs :) (I do not know exactly: 4164-150 ns?). On the 12V PSU, I'm no expert in this field, but as far as I know the voltage r...
