Oric repair in Noel's retro lab
Just in case you missed it. Very nice repair video.

Very interesting. The choice: we replace all the RAM memories, or we go crazy...

He said that the test ROM does not indicate witch RAM memory is faulty, he didn't listen to the diagnostic synthesis voice ?
Re: Oric repair in Noel's retro lab
Voice????
I have Mike Brown diagnostic cartridge, did not remember it doing any sound of any kind.
I know April 1st is coming soon, but it's not there yet

Re: Oric repair in Noel's retro lab
+1! He is using @mikeb's ROM Diag and the "speaking" Diag is by FF aka @euphoric .
Re: Oric repair in Noel's retro lab
Is it a recent mod, does that mean I need to flash another eprom?
Re: Oric repair in Noel's retro lab
Hm, diag.rom 09-Jan-2004 10:50 imho not so recent .
Works with Oricutron (set its name in oricutron.cfg).
Re: Oric repair in Noel's retro lab
So seriously, how is it supposed to work, does the rom contains some samples that are replayed with the YM/VIA?
Do we know what the code does, because there are some ways to replay samples that don't work on some Oric, like the end sample in the VIP Giga demo does not work on either my Atmos or Pravetz, but it worked on Twilighte's machine.

Re: Oric repair in Noel's retro lab
I have no technical details but I remember Fabrice's idea was to be able having information even if the sreen display was out of order.
Now, there were speaking programs very early in Oric life, IIRC "Voice" in Théoric, maybe another one in Micr'Oric, and also for instance the voice in Trouble In Store. Don't know what the rom is using, but I tried it once just out of curiosity, and recall it was rather hard to understand to the 1st listen

It's like WAV playback (i.e. samples). I don't know which of the 2 possibilities is used - volume manipulation or king of PWM.Dbug wrote: ↑Sat Mar 19, 2022 4:41 pm So seriously, how is it supposed to work, does the rom contains some samples that are replayed with the YM/VIA?

The Diag writes values in RAM and then compares if they mach then it speaks a number and continues ... something like that!
Anyway, it's really impressive because it doesn't use RAM only A,X,Y and as @Symoon said it's useful even with broken video.
