Re: The Watford Gap

With RO311 on an A3000 and an A3020 the screen border is the same base colour as the pinboard, I seem to recall. I think that's a !boot configuration thing as when I was using the A3010 earlier with CMOS settings cleared and not booting from CF, the screen border was grey. IMG_7993.jpg It's only wh...

I guess it depends on your browser and OS but I right click on the header of the post I want to link to then choose copy link.

I then press the chain icon to create a [url] /[url] and paste the link in-between.

Hello again Andrew Have you got a picture of the IDEFS utils directory? I definitely got 2 drives working, see picture although as I posted I couldn't get the IDEFS boot drive booting with an updated Uniboot application, I'm hoping to have a go at this soon. All sorted now thanks and documented on ...

No problems at all, but it doesn't appear to support any partitioning, so I'm stuck with 500MB accssible on a 2GB SD card. Although Watford IDEFS doesn't ...

Just did a quick experiment to check the old oscillator once off the A3010 motherboard: IMG_7965.jpg IMG_7968.jpg As expected, same result as when running on the board and with its output connected to the ARM250 pin 4. I had a 40MHz oscillator lying in the spares drawer, so built up the same circuit...

Re: Today I overclocked my A3010

Hi Folks,

I don’t suppose anyone here has a spare 72MHz Crystal oscillator they can sell me?

I’m looking to replace the 4 pin X4 (14 pin DIL package footprint) on my A3010.

I’ve ordered a modern pads version for now but would be nice to fit the correct type if I can

Many thanks

Re: A3010 Sick

Oh wait, looking at your photo it seems like the original part really is a 72MHz one. For some reason I had got it in my head that it was 36MHz. So, 72MHz is more difficult. Mouser offer CB3-3C-72M0000 but only if you buy 1000 and wait 12 weeks, neither of which I assume you are keen on. Digi-key o...

Re: A3010 Sick

Depends how authentic you want it to be, I guess. Farnell stock MCSJK-6NC1-36.00-25-B which looks like it's electrically suitable (assuming the original part was a 5V one) but it won't go on the same footprint. I don't know what the original part even was, though if you download the TRM it might ha...

Quite possible, crystals certainly do fail. I think pin 4 is the main clock for the ARM250 so without that not much is going to happen.

Certainly worth replacing X4 and seeing if the situation improves, I think.
Definitely. Will report back and thanks all.

Re: A3010 Sick

That's a bit sad. The address lines on the ROMs are the latched versions, but I think they should still be tracking what the ARM is doing. Are you sure nRESET is reaching the ARM250 correctly? If you have 25MHz coming out of pin 11 then it must be getting the 25MHz in. Is the 36MHz clock also prese...
