TZX file format: Hardware IDs

Block 33 lists the hardware a tape needs or supports. Each entry is three bytes: hardware type, hardware ID and an information byte. A tape that runs on a plain 48K Spectrum needs no entry. These are all the types and IDs in the TZX 1.20 specification.

Information byte

Value	Meaning
`00`	Runs on this machine or with this hardware, but may not use its special features
`01`	Uses the hardware or its special features
`02`	Runs, but does not use the hardware
`03`	Does not run on this machine or with this hardware
