N-Vinylcarbazole
N-Vinylcarbazole is an organic compound used as a monomer in the production of poly(vinylcarbazole),[3] a conductive polymer, in which conductivity is photon-dependent. The compound is used in the photoreceptors of photocopiers.[4] Upon exposure to γ-irradiation, N-vinylcarbazole undergoes solid-state polymerisation.[5]

gollark: This is underspecified because bee² you, yes.
gollark: All numbers are two's complement because bee you.
gollark: The rest of the instruction consists of variable-width (for fun) target specifiers. The first N target specifiers in an operation are used as destinations and the remaining ones as sources. N varies per opcode. They can be of the form `000DDD` (pop/push from/to stack index DDD), `001EEE` (peek stack index EEE if source, if destination then push onto EEE if it is empty), `010FFFFFFFF` (8-bit immediate value FFFFFFFF; writes are discarded), `011GGGGGGGGGGGGGGGG` (16-bit immediate value GGGGGGGGGGGGGGGG; writes are also discarded), `100[H 31 times]` (31-bit immediate because bee you), `101IIIIIIIIIIIIIIII` (16 bits of memory location relative to the base memory address register of the stack the operation is conditional on), `110JJJJJJJJJJJJJJJJ` (16 bit memory location relative to the top value on that stack instead), `1111LLLMMM` (memory address equal to base memory address of stack LLL plus top of stack MMM), or `1110NNN` (base memory address register of stack MMM).Opcodes (numbered from 0 in order): MOV (1 source, as many destinations as can be parsed validly; the value is copied to all of them), ADD (1 destination, multiple sources), JMP (1 source), NOT (same as MOV), WR (write to output port; multiple sources, first is port number), RE (read from input port; one source for port number, multiple destinations), SUB, AND, OR, XOR, SHR, SHL (bitwise operations), MUL, ROR, ROL, NOP, MUL2 (multiplication with two outputs).
gollark: osmarksISA™️-2028 is a VLIW stack machine. Specifically, it executes a 384-bit instruction composed of 8 48-bit operations in parallel. There are 8 stacks, for safety. Each stack also has an associated base memory address register, which is used in some "addressing modes". Each stack holds 64-bit integers; popping/peeking an empty stack simply returns 0, and the stacks can hold at most 32 items. Exceeding a stack's capacity is runtime undefined behaviour. The operation encoding is: `AABBBCCCCCCCCC`:A = 2-bit conditional operation mode - 0 is "run unconditionally", 1 is "run if top value on stack is 0", 2 is "run if not 0", 3 is "run if first bit is ~~negative~~ 1".B = 3-bit index for the stack to use for the conditional.C = 9-bit opcode (for extensibility).
