Re: Diagnostic cartridges?

I think LED2 is indicating a RAM failure. Ha ok, so LEDs are basically just writing a number in binary, which is the status code? Guess I'll have to unsolder the ram chips and try to replace them, see if that helps. Thanks. Thanks SteveM -- it would be helpful if whoever is making and distributing ...

Re: Cumana reborn issue

If it is that, is there anything I can do to rectify it myself? Adjust it! :) VR1 is supposed to adjust a monostable (delay) which delays a copy of the Oric 1MHZ clock. According to notes on the Cumana schematic, it is intended to create a signal that is 150ns *ahead* of the Oric clock signal, so t...

Re: Oriclopedia: A series of videos on all things Oric

If we had to explain the whole operation of the ULA (hidden RAM access) it would have been too long and too technical, but for the graphic possibilities of the chip, we understand well and it is not too long. Good job! :wink: For a YouTube video, yes it would be very difficult to cover the whole op...

Re: Connectivity problems (again)

I waited a bit to see if anyone would report problems - as nobody did, .... t took me five attempts to reach the forum, so here I am again I would have posted, but it took so many attempts to try and *read* the forum up to date and post a reply (put it on the copy/paste buffer just before hitting "...

Re: John Gage reviews Damsel In Distress!

Would it be fairer to ship Damsel In Distress along with the "cheat-code secret keypress" (requires 10 key depressed simultanously ... and for some reason the published code in OUM/Your Oric didn't actually work for me, I ended up finding another set of 10 keys that worked on my machine!) That way y...

Well worth building these as they can give you a spark to create something :)
You'll definitely get some kind of spark, as he tends to modify circuits with the power on.

@Chema thanks for that -- that's even better than my memory of it :)

Oh, sorry! That was very poorly worded. Read it "one is claiming to support WAV...".
No need to apologize, I got your meaning, I was just making a funny. Your point was absolutely right though.

(Disclosure: I have written can't-be-bothered "WAV" loaders for myself!)

I did watch this video a couple months ago, it was quite cool, specially when I knew in advance why this and that happened :) There's 6 videos in the playlist (recent additions) with more to come, so you may need a refresh :) But even knowing the 6502 quite well, it is interesting seeing this throu...

Bearing in mind the subject says "Connecting to a tape recorded in 2019", and it's now well into 2020, you will also need to purchase a longer lead.

Re: Meurtre à grande vitesse, why there is not a TAP file?

WAV is a bit dodgy because technically it's only a container format ... as you're claiming that you support WAV and you don't really. Just a subset. I claim nothing! :) Not my tools, not my problem! But you're absolutely right -- WAV is being used here in the context of WAV2TAP/TAP2WAV etc. which l...

65C02 computer from first principles.

Just thought I'd share this link on here -- although it is not Oric related, this guy is putting together a 65C02 based "My First Computer" on breadboard, and I found it really interesting. He really is doing a good job of explaining as he goes along, including some things which become a teaching mo...
