Acorn Atom Replica build

Well done Mr Jonnie.

I'm going to look at overclocking mine to 2 and 4mhz at some point too.

Thanks. Mine is still not 100% complete, I need to get a few odds and sods and a speaker would be nice too, but it does at least run.

I'd like to add an FDD interface so that may well be next :)

Glad to see that you've beaten it into submission!

:thumbup:

Thanks, but bloody annoying that CPU died, it was in my drawer of working parts.

I'm down to a single spare 6502 now...

And the dodgy key switch is fixed. Turned out that the switch was fine, but my soldering wasn't...

So a swift reflow of the pin and the key sprang into life.

All the ICs are back in now and it seems to be working as expected. Happy days :)

I did get a FDD PCB but instead got an AtoMMC from one of the guys on Stardot

Hmm, that sounds like a plan, how does it install? Is it in one of the ROM sockets?

I got a year at the same time, which is a programmable rom board, so that had the rom fort. In my Atom I've got it sitting inside, off of one of the small headers. Apparently you can split half of it to have the SD card slot outside but I left mine inside.

Thanks will take a look.
