OK you're most welcome to it. Just let me have your address and I'll pop it in the post for you. Can you PM yet?

Is a ] key still required? I have one. Or is it a [ ?

The version online is very old and incomplete, there is a much more up-to-date version here:

What's the socket for? EEPROM? It all sounds quite exciting Roland!

If you need a spectrum edge connector I can sort you out.

I am curious what really caused the problems. Are you willing to figure that out by for example comparing the most critical signals at the good and the bad ic's? I suspect that one or all are marginal in some parameter or other. I'm no detective though, and wouldn't know where to begin with an anal...

I suspected the 8255 as occasional flips into graphics mode could be explained by it. And indeed changing it out has solved the problems. Ctrl-G now sings beautifully :lol: It was still glitchy though so I set about swapping out chips and the 3 clock related bods around IC44 were my best educated gu...

@Dace* - I've tried a couple of AtoMMC boards and they behave the same so I don't think it's a mechanical issue, but thanks for the suggestion. Further to that I undid the YARRB mods and swapped in my RAMROM and lo, the machine works perfectly. I can reliably run every program in the collection, the...

So after much probing and messing around I'm still a little stumped. I've checked jumper positions and clock waveforms and I'm happy they're in spec. No IRQ jumper is present. It's an R6502. I've changed the LS04 clock conditioner for a new chip even though the scope showed some nice clean signals. ...

So weirdness continues. This morning I thought I'd get some measuring done and lo, the machine is (almost) behaving itself. I've done nothing, it's in the same state I left it. But I get a (mostly) stable boot, ability to load the menu from SD card, and even run some of the software. I've written a ...

Hi everyone. As another data point I've currently got a machine on the bench which is showing instability when YARRB is installed. I haven't yet reverted the machine to a pre-YARRB configuration but that's on the cards. The machine was post renovation and said to be working when I received it, but I...

Go for it!

Peripheralmon. Gotta catch them all...

Is there a PCB I could buy please?

Nice

Yes please Dave!

I'd like a board please Dave. I'll be happy to solder the smd bits for anyone unwilling.

Beautiful work as always, Phill!

32? what is this number?

You don't even have to be nice.

Flicky.

Not only because it's a great game but also ...

Is that an issue 3 board Richard?

Samtec do a range of pre-made cables. Check out their range and if you find anything suitable let me know and I may be able to get one for you.

Would something like this do?

I have a few spare keys - you might get lucky and not need to cannibalise the iss.3. Like Dave says - there's no Atom that can't be fixed.

Yup.

Thanks - there's a lot to trawl through . Chemical Computer (comedy) has the effect mixed in but nothing else jumps out, not even in 'Belgium' or 'Orgies'.

* Caution - may contain Grotbags and Emus * There's a sound effect common in 80s kids' shows, commonly used for anything from bubbling cauldrons to unorthodox machinery. It's here quietly in the background. A kind of semi-tuneful blarping and blooping. https://youtu.be/n9jmNVPHirQ?t=222 Does anyone ...

I use Hakko T18-C3 . The idea that you need a tiny tip for fine work is nonsense. A tiny tip won't deliver the heat you need. It's all about the flux. Also like Daniel said don't use huge amounts of solder. In the video below I'm just using a tips worth. If you connect 2 pins then just either drag ...
