Here we go guys, I nailed it! First, the white rectangles I was having before, the Oric used to be stuck on that screen: [IMG] And the culprit...
Good idea, I will.
Now that the RAM chips are replaced with new ones, I have white still rectangles on a black screen display. You guess it, it is not fixed yet....
PMSL!
Even here in France, I remember learning computing and playing with ZX81 computers at school back in 1986! Reposez en paix Messire Clive Sinclair!
Ah yes, we spent a good time in Duxford! Hope we can do it again!
A quick note about the Oric. First I realised that the SCART cable I built was faulty, I could never display a picture with it. Once fixed I...
Hi Tim! Isn't there a usefull antispam plug-in available for this forum maybe? You could then let the regisrations open...
Unfortunately it looks you were scamed by a fake chip from China... It is sadly usual, I also was once scamed with a fake TMS9929, just like Noel...
I didn't have a lot of time to look after the Oric these days, too much work! But it is cooling down in July (not the weather), so I'll let you...

Hi Rich, the 12Mhz and 1Mhz clocks are present and have the appropriate shape, like the ones shown in the service manual, excepted for IC9 pin 6...
Thank you richie! :D I printed it!
I forgot to mention that I found various clocks are present accros the board , but I'll recheck thoroughly. Many thanks for your help.
The resistances are consistent, I guess it is ok. I don't have a logic analyser, but various multimeters, logic probes, and a medium quality but...
I have tested the resistance from all the chips including the 6502, 6522, AY, ROM, RAM etc. They all give 180ish Ohms. It would mean they are all...
@Vyper68 Yes, good idea! I will.
Hi guys,I have received and installed the new 7905, and now I have the correct +5V all around the board. But it's still a no go. I have noticed...
