It's key advantage is that is available at boot up.
Its key disadvantages are that code cannot be entered in assembly language
and there is no ability to save to memory devices.
The available memory are for programming is `0200-EDFFh`. The following areas are reserved:
Memory Area | Function
------------|-----------------------------------
`0000-00FFh`| Jump and restart (RST) vectors
`0100-01FFh`| HBIOS configuration block
`FE00-FFFFh`| HBIOS proxy
Commands can be entered at the command prompt `>`
Automatic case conversion takes place on command entry and all arguments are expected to be in hex format.
The current memory bank in low memory is displayed before the prompt i.e.:

P xxxx - Program RAM at address xxxx
R xxxx [[yy] [zzzz]] - Run code at address xxxx
Pass yy and zzzz to register A and BC
