This is an unusual and unexpected program, a "stand alone" Monitor/Disassembler. Usually these are produced as a support program for a company's assembler, and there is also the fact that there are already several on the market for the aging Spectrum.

With this in mind the program must stand on whether it is easy to use and any special features it has.

Taking the latter first, Eastmon make a big thing about the fact that the DEFB's following a RST28 command are correctly interpreted (the 'use the calculator' command as Toni Baker's fans will know). It also correctly copes with the Interface 1 RST's.

You may or may not find this important, its useful to know that it'll cope though, especially if you use them a lot.

The program comes complete with a comprehensive, word-processed, dot matrix printed, fourteen page manual. It's all in there, but if your eyesight is not 20/20 then you may have problems with the tightly packed text.

Yep, it's easy to use and all the features that you are likely to need have been included, full printouts to any type of printer system and full details of the state of all registers at each step.

There is a choice of output, either a straightforward address, code, mnemonic print or a full frontal, everything exposed, printout in minute detail.

It may be late in arriving but it certainly does not suffer in comparison with established existing monitors. If you haven't got one and you spend a lot of time programming in machine code then this is highly recommended, it will certainly provide you with the information needed to track down that elusive bug; even in RST28 sections!
