The source archive can always be found at:

The ROM images were downloaded from:

The preferred form for modification of the Spectrum ROM itself is not
available; I understand that even the copyright holders no longer have
the source code. The Incomplete Spectrum ROM Assembly was downloaded and
is available from:

  http://www.wearmouth.demon.co.uk/

1) What exactly do you have to do to use Sinclair ROMs in an emulator, such
as acknowledgements etc?"

Amstrad are happy for emulator writers to include images of our copyrighted 
code as long as the (c)opyright messages are not altered and we appreciate
it if the program/manual includes a note to the effect that "Amstrad have
kindly given their permission for the redistribution of their copyrighted 
material but retain that copyright".

"2) Can you charge a shareware fee for an emulator that uses the Sinclair
ROMs?"

No. No one should be charging for the ROM code because (as a result of the
point above) there are loads of freely available images anyway. If I ever
thought someone was charging for the ROM images then I'd make them available
as a free download on the www.amstrad.com web site. Naturally I imagine that
some emulator writers want to charge a shareware fee for the code they have
written and we have absolutely no problem with that as long as they aren't,
in any sense, charging for the parts of the code that are (c)Amstrad and (c)
Sinclair.

"3) Can you modify the ROMs, for instance to enable tape loading and saving,
and if so what are the requirements?"

The ROM code is simply a tool to let the emulator writers make a program
that works as close to the original machine as possible. If they choose to  
modify the behaviour in any way then that's entirely up to them (I guess you
could say that that is exactly what an emulator IS doing (ie modifying the
screen output and keyboard input to go via the PC bits)!!)

"4) Can you distribute modified ROMs?"

If you like (with that (c) proviso).

There are no restrictions on my part and one of the purposes behind the
file was to provide a documentation forum that didn't compromise the
copyright of the well-known book that introduced me to the innards of
computers or have any copyright restrictions of its own.

Anyway feel free to distribute the file.
