I was thinking about the communication between multiple Oric, and when looking at what we had already in the machine, I checked the VIA 6522 datasheets (http://archive.6502.org/datasheets/mos_6522_preliminary_nov_1977.pdf) and in particular the first part of the document left me thinking: The MCS652...

I guess that anyone who tried to make a device for the Oric that connects on the expansion port can testify about how "reliably" the hardware behaves

- We also would like to limit attribute constraints (so we can have six pixels of different color side by side on the same byte, for example) That's probably the most hard to achieve from your list ... The ULA as it stands cannot be convinced to do that, and I'm struggling to think how two ULAs cou...

You guys are totally crazy. And I love it!

Great

Now, you are not excluded in giving your opinion on what you think would be desirable features - in the hypothetical situation where you would support the system -, if only for a small funny game/tech demo ?

Done! It work always now! Replaced button with Arduino (to avoid ringing) and following particular power-on sequence Orics start synchronized. :twisted: That's super cool :D Now regarding the color mixing, there are multiple things to consider: - We probably still want normal Oric software to run a...

As long as they are direct messages.
The forum is not able to send emails, that's why we had all these problems with registering, could not find why it happened (the server itself is sending me cron notifications when there's a problem, so I know that works at the system level)

... and to summarize although it's possible to control ULA counters, it's not enough for stable work

Any idea about why it's not stable enough?

As I recall the branch issue was just that - your work could've been done on another branch rather than an entirely separate, non-visible repo. But okay, your choice to prosecute your time however you wish. Its just that, at the time, you weren't the only one investigating the Cumulus firmware, and...

There are a bunch of issues: - The code itself is not difficult to understand and modify, but the UI code is impacting the performance of the actual cumulus, so things like showing the track or sector number in real time actually does impact loading time - The tools required to modify and rebuild th...

The principle is not very complex: - The ORIC outputs 1 bit RGB colors, which can be counted as a color value index from 0 to 7 - The card intercept this output and use the index to control the Thomson DAC/palette chip to replace the input value by another value using a small array internally. That'...

Fixed
I did a last minute change and forgot to test that it still worked.

So, now we have the complete downloadable files for;
- Theoric
- Microric
- OricComputing
- OricOwner

what would be cool is to get PDF versions of the 25 issues of Rhetoric (specially now that the old site seems to be gone?) as well as Oric User Monthly.

The http://www.defence-force.org/computing/ ... /index.htm is now updated with the content of the PDF provided by two contributors

Thanks!

I had similar experience with my Atari ST where in some cases I would still see some remnants of previous graphics in memory at least 10 seconds after I had switched off and on again the machine

I do not, but if you manage to locate some, I could add them to the library:
