Cumulus Issues
Re: Cumulus Issues
Sorry Chema,
my oscilloscope is rather old and could not make snapshot. Maybe I must try to do this with camera.. I'll thing.
Because I don't know where to look. Is there any control point on the pcb to look with oscilloscope?

Re: Cumulus Issues
I've been reading through the first few pages of this before I test my Cumulus. I'm a bit confused and think there is a real need for a set-up guide.
There is nothing in the instructions sent to say I needed a different power supply.
There was some mention of different software early on in the thread and I'm not sure what if anything is required on the card, (apart from disk images).
Writing to the card isn't easy for me. My camera doesn't allow it and the printer slot doesn't seem to do anything. I've had to find an audio recorder. I guess some computers have the right slots but mine doesn't so it makes writing to a card a bit tricky. I wasn't sure if the Cumulus could be connected to the PC but it doesn't appear to have any slots.
As you can see I'm not to good at working these things so a bit of an 'Idiots Guide' would be really useful.

Re: Cumulus Issues
I'm using a generic 2 euros USB adapter:
- plug it in any USB slot on the pc
- put the sd card in it
- read and write files
I've been using that for years, it's much faster than using the camera software, and it works on most machines without even installing drivers

Beware though with Windows XP SP3: it crashes SDHC cards when using an external USB SD Card reader. Lost some photos this way.Dbug wrote:I'm using a generic 2 euros USB adapter:

The solution then is to reinstall XP SP2 drivers, or use an internal reader.
Problem seems to exist only with XP SP3 combined with SDHC.

Re: Cumulus Issues
Thanks. My partner Ally has a USB card reader I can use - I never knew she had one. I don't think she has used it as we bought a card reader as part of the PC she got.Dbug wrote:I'm using a generic 2 euros USB adapter:

I'm on Win7 64bit which works most of the time but seems to clash with some software. (I can't get Adobe Flash working at the moment - real pain!)
Re: Cumulus Issues
I've got a 1.5amp power supply. Is that going to be OK or is it over-cooking it?
I'm worried that the Atmos might not like a heavy load.

Re: Cumulus Issues
it'll be fine, the oric will draw as much current as it needs.

Re: Cumulus Issues
Whatever the device, you could put a 2TA that it will not matter, what is really important is to have the correct voltage, the correct polarisation, and enougth Amp for the device, i.e. if the device want a 500mA input , you need at least a power supply capable of delivring 500mA. A bit more is generaly needed, especially on cheap power supply.
With high rated amp supply, you will only have a problem if there is a short circuit. The more the supply is able to provide, the more the short circuit will be worse. But this should never happen ^^

Re: Cumulus Issues
Thats correct, but with one caveat, high rated power supplies can have problems maintaining the advertised voltage if they are under-loaded, but I don't think it really applies here
Re: Cumulus Issues
I am using a ZX Spectrum + 1.5 A PSU (with the polarity reversed) and it works perfectly with Oric+Cumulus. And it also has a switch to turn it on and off, which is a bless.
I also read somewhere that you could use a 7.5Volt PSU, better than a 9V, which will make the Oric's regulator dissipate less heat. That is surely good for the machine.

Re: Cumulus Issues
Good to know, as that's what I planned to use once I get an adapter to reverse the polarity (don't want to cut the cable so I can still use it vwith my Speccy).Chema wrote:I am using a ZX Spectrum + 1.5 A PSU (with the polarity reversed) and it works perfectly with Oric+Cumulus.
Re: Cumulus Issues
Tested my two Cumuluses today and finally got them working. All the problems were, in the end, related to incompatible SDHCs. Managed to find a working one eventually
Re: Cumulus Issues
does that mean an oric demo from fit is on the way?
