HakPak is small Z80 toolkit for the SAM Coupé, featuring a disassembler and a selection of memory viewing/searching/editing options. It need just a single 16K page to run in, sharing the existing display with BASIC.
As a regular user and fan of the Multiface Genie disassembler on the Spectrum, I chose a similar style for the HakPak menu and status lines. Most actions require just a single keypress, to avoid having to type out commands in full.
Despite the program being rejected by SAM Computers Limited, it was further enhanced and later released as TurboMON.
