I had an Acorn Atom.
And here it is.
Here's the inside, showing the multi-ROM board I fitted and the 24k memory board that I built from scratch. No custom PCB, just the board and a lot of wires between the sockets.
I dug it out of the loft last year and sold it on eBay but before I did that, I connected it up!
