+1 to that. Baby steps. Commit in what you have, as it is, and learn about how the system works. Especially branching. Branches don't cost anything and are perfect for experimenting. Keep master clean/working at all times. Work in a branch until it's looking how you want it to then merge that back t...

This is very exciting. If I wasn't so busy I'd be looking for my LCSoft board right now. I'll be happy to help out with traces for other machines but it will be a while before I can get to a z80. *edit* I've written a few things for the ZX81 in my time, if you'd like the source for a game (16k requi...

Brilliant work (as always ) Kees!

I have to admit that I didn't consider mounting on top like the econet board - I always just imagined popping the main interface board underneath the atom motherboard with the slot card hanging outside. I didn't think there was room on top as it's pretty cosy there under the lid. I was wary of short...

Yep that's it.

Anyone from here going?

I'll be there - I'd love to put faces to handles, as it were.

I buy most of my xilinx cplds from china via aliexpress. Some have looked odd, with slightly too-large lettering or some other visual artifact that aroused suspicion. They have all been fine though. They all programmed first time, retained their programming, and there have been no weird occurrences ...

Quite far gone I'd say, like this Atari 800 xl.

I've never used bone, and I'm always happy with the finish as-is so I can't be any help there I'm afraid. Sorry

I use vinyl dye to colour plastics. It apparently bonds with the plastic rather than covering it, so it doesn't chip or peel. It also doesn't affect the texture of the surface you're painting as much as a regular paint. The colour range is slightly limited though, and it's more expensive. Still wort...

I have boards available. They are built on demand and are usually customised according to the demands of the Atom that they are destined to fit. Feel free to email me at charlie_robson@hotmail.com.

See first post regarding email address, thanks.

The green LED indicates an SD card access. If there's no card in the interface it won't initialise, so no irq. IIRC.

Sounds like a fun project. Is this for personal enlightenment and education?

one thing i noticed is that when the ATOMMC2 is unplugged, the ACORN ATOM + ATOMMC2 never comes up. i will try pulsing the irq line and see if the heading changes to the ATOMMC2 ... :) The interface generates an IRQ at power-on. No interface, no IRQ. No AtoMMC. As you might expect. When the OS ROM ...

This is as designed. An error in the PCB means that I need to re-route a pin. It is perfectly normal and nothing to worry about. The chip in question here is an address decoder and it has nothing to do with SD card initialisation, that is handled by the PIC processor. MMC and SD cards are tricky bea...

The cable is now integral to the board. It's s tiny bit trickier to put together but it makes more sense.

Manual linking's no fun though, is it?

E000 AtoMMC requires a patched FP ROM.

Flux. Problems at home? Flux. Car won't start? Flux. Toast burned? Flux. Donald Trump? Flux. I could go on.

Too much solder perhaps? You need only the tiiiiiiiinyiest touch for a tqfp. A bit more for a sodip. And flux. Lots of it. The more toxic the better :lol: Moar colons. I don't tack any more, i just flux up, hold the chip in the right place, touch a tiny bit of solder on the tip. With a wet the tip t...

10.1 GO TO 22.3

Yes, still available. Pre-built only though. Disk image support is possible and also the ability to use individual files on the card. There is an (old but still relevant) manual online here. I should really update it

No.

The first prototypes attached to PL7, and were bit-banged using the VIA. There have been no boards made like this for many years. All AtoMMCs are pic-powered.

Haha actually it's disgusting stuff but I have a good fan Colophony == Rosin.

Indeed I do.

I'm sure it'll be fine, they're just not for me and the kind of work I do.

A couple of you have now mentioned drag soldering, and it's something I've previously watched a video tutorial for. I'm wondering how easy it is, really, for someone who's practiced at soldering and neither ridiculously dextrous nor a klutz? I'm guessing I should pick up a few cheap components to t...
