Hilton is well known for its serious software, particularly banking systems, so I was interested to see how successful it had been when turning to machine code programming and manipulation. Disassembler comes in the most basic of packaging: a computer-printed inlay card and a standard cassette case. And basic instructions are given. I suppose Hilton considers anyone purchasing a disassembler does not need to be told which column is Hex, which is mnemonics and so son.

One loaded, it lies in memory while you write Basic programs, load machine code programs or do anything else with your Dragon. On typing EXEC &H7725, the computer starts the disassembler.

It offers a pretty basic range of options. You can direct the disassembled program to either printer or screen display. Once you give it the required starting address, it displays a screenful of code in the standard way. The program is, then, perfectly adequate and suitable for anyone using machine code.

The price is reasonable, but it may still be better to buy assembler/disassembler/editor all in one.
