1) J.G Ballard's Atrocity Exhibition as closest to an (expanded, to some extent architectural) instruction set for an imaginary CPU.
yet to be codified
2) circular memory (bubble is similar).

Of interest here is the ghosting of registers:
There are two sets of six general purpose registers + accumulator and flag registers (duplicate set swopped (values exchanged) by the Exchange instruction) - "The alternate set allows operation in foreground-background mode or it may be reserved for very fast interrupt response."
(From Z80 product specification).
Further 16 -bit wide registers for index, stack pointer,program counter and split (down to 8-bit) interrupt and memory reset. Also interrupt and other flip-flops.

also addressing mode

ADD HL, ss

Binary form of opcodes
Example: LD r,r'
the 8-bit binary opcode is
01dddsss
...where "ddd" is a three-bit field specifying the destination,
and "sss" is a three-bit field specifying the source.
is shown below as
r r'
01 xxx xxx
overmapping Salo/Sadean life coding onto instruction sets
in the first instance (or with Alice/Looking Glass/Ripper whole codified mapping - to commence in process).
to start by way of circles as registers: circle of manias, circle of shit, circle of blood (with Pasolini borrowing from Dante's nine circles of hell).
