That thing looks like a ZX81 had sex with a Philips scope.
Oh, but the real wonders can't be seen in a photo, they have to be experienced in person. Nothing beats fondling (or poking hard in this case), reading, and the subsequent bafflement followed by sheer annoyance.
But if you really want, a little googling reveals:
I WARNED you not to look too closely at it! Like the visage of Cthulhu, it shall surely drive you insane!!!

"That way lies madness."

I knew there was a good reason you could get keyboard condoms for ZX81s!
I had one... with the 16K expansion pack, parallel port riser and you guessed it - an Epson FX-80 (MX-80?) 9-pin printer. ASCII pr0n never looked so good!
In a fit of aggravation, I spent a whole weekend rewiring a CHERRY keyboard (manually toning out and building the matrix switch by switch) onto it from one of the old NASTEC Case2000 workstations I had left over from recycling a police station. That of course did NOT help the pitiful workspace it had to offer, but it DID at least feel almost like a VIC20.

Every time somebody says "ZX-81", somewhere a nerd feels an icy chill run down his spine.
