Low-tech computing for Minetest

Memory access

Memory access in this mod occurs over digilines, with the channel as the prefix plus the memory address, and the message as either the new value or 'get' to get it returned, so for example:

Prefix	Address	Value	Channel	Message
A	1	4	A1	4
Default	15	get	DefaultF	get

T400

Instructions

TOS = top of stack

ins	function	mnemonic
4095	duplicate TOS	dup
4094	swap TOS	swp
4093	read memory from TOS	read
4092	write to memory from TOS	write
4091	add TOS	add
4090	suptract TOS	sub
4089	jump to TOS	jmp
4088	skip if TOS = zero	sez

T416

The T416 is a 16-word memory. It stores 16 ints and is accessed as described in the Memory access section.
