Intel 8085 assembly for z88dk: Zilog mnemonics, full opcode map (flags K/V, timings), and extended-instruction usage. Strong rule: stack-only locals and intermediates; static/BSS only for cross-call state. Prefer when writing or reviewing 8085 library asm, mapping Intel↔Zilog, choosing stack frames, K-flag loops…
