That was supposed to be a working computer, even after the cat jumped over it

My experience with such boards is that the connections are less than reliable. I find it difficult to believe something of that complexity could work.

Presumably the constructor used a new board to minimise that.

Waste of time.
That is cheating, they used wires with different colours :-)
Some used wire-wrap to build individual boards as well as backplanes with only yellow wire-wrap wires.
The way I "do" prototyping stuff with logic now that isn't high-speed enough to require dead bug on copperclad is get everything in SOIC and mount it to these "surfboards":
SOIC is large enough that it's pretty straightforward to hand-solder. Then mount it to a high quality piece of "blob board" (I like green the bests) and use fine solid-core silver wire, maybe 26 gauge to directly tie together the blobs.
Work in progress:
Why not put the wires on top where you can see them?

Or, for fast stuff, skip the wires.

I use the swanky blob-board which has very large rectangular pads, so there's only a thin gap of mask between holes. If I'm careful in my layout I can just make most of the "traces" out of solder runs, like a single-sided PCB.
I didn't know anyone still made old-timey SRAMs in a DIP package. The Alliance parallel SRAM is nice and pretty cheap too!
