Swap working Oric Atmos for .. ?

Post by ibisum »

As it happens, I have a spare Atmos in my collection which I was thinking about lately .. it'd sort of be nice to have something else in the collection.

So if anyone is interested in swapping, I'm willing to trade a perfect working-order Atmos, in original box, for .. anything really. Make me an offer - I'd love a ZX Spectrum, or CPC Amstrad, or something similar. No C64 though, I've got one already .. ;)

PM me if interested and lets make a trade!

Have you tried this machine with a cumulus?

To test if something is able to fix the cumulus issue, yes it's better with an atmos (or a 1) that does not like it :D

Well I can find one in the stash that qualifies. What do you want to swap for it?

I can supply an Atmos that doesn't work with the Cumulus.

Did you read my post on another thread about an Atmos with cumulus issues that were totally solved after changing its ULA?

Just in case you have more than one to test.

I also suggested to collect info about the ULAs in orics that work with cumulus and those that doesn't.

Steve, if you can lend me one for a period of time so that I could analyse exactly what the problem is.
Chema, yes we need to understand the problem and checking the ULA will be a good knownledge, but swapping ULA is not a definitive solution, this is just trying to put an ugly patch on a real problem, it may solve on some Oric, but not on other especially if the problem is the one we think (noise on the expansion port that fool the ULA/Via/CPU)

But it is true tha the main culprit for this problem may be the ULA, that does not tolerate the noise on some of the IO line..

I know it is not a universal solution, but it may shed some light on the cause of the problem and, more importantly, may solve the problem for people with non-working cumuluses...

If my Oric did not work with my Cumulus and I knew that acquiring one of those ULAS on Ebay I could solve it, I'd certainly try.
