!Spectrum/PCSNAPS/SPECUT~1/!!README

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

			Spectrum Emulator Utilities
			===========================

The Programs in this directory were developed for use in an attempt to decode
the snapshot format used the Speculator *Specsave/*Specload commands.

Although written to be general purpose routines, in order to avoid repeated
entry of the same data during devopment they have explicit file pathnames
etc. hard coded into them. If you wish to make use of them then you should
ensure that you either 

	a) Replace hard coded references with your own choices
	b) Remove hard coded references and uncomment input routines.
     or c) Ensure your directory structure is setup as follows


		  <Spec$Dir> = adfs::IDE5.$.SPECTRUM.!Spectrum

New = Speculator snapshot taken immediately after an initial *Spectrum
Poker = Snapshot of basic program to initialise z80 registers to known values
x = Snapshot of machine after *Specloading and then RUNning Poker

For those occasions where the current directory is used I had it set to <Spec$Dir>

                 discoveries that you may make. )
