From: Richard Clayton <richard@turnpike.com> To: rison@hep.phy.cam.ac.uk Date: Thu, 28 Sep 1995 15:51:28 +0100 [...] The situation is that the ROMs (of all the CPC machines) are joint copyright between Amstrad and Locomotive (Amstrad own the "firmware" copyright and we own the "BASIC" copyright - so about half the ROMs each). That is why both our names appear on the start-up screen ! so there will be no doubt !! Of course we wrote it all, but Amstrad bought some copyright off us so that we could not sell it all to some third party to make competing machines. Anyway ... we are happy to give you permission to distribute our copyright material with your emulator program without charge provided ** that you mention in the documentation which goes with the emulator that it remains our copyright, you just have permission to distribute it and ** provided that you continue to offer your program under substantially its current terms. In particular without asking for any money for using it. this along with Amstrad's permission will I think allow you to distribute the ROMs along with your emulator without problems.

From: CLIFFL@amstrad.com To: Mark RISON - Esperanto parolata <rison@hep.phy.cam.ac.uk> Date: Thu, 30 Nov 1995 09:18:03 +0000 Distribute anything you like subject to including the relevant copyright notices. Amstrad certainly won't come after you with a big stick and when I tried to locate someone in Novell who knew about the ownership of CP/M I failed miserably so I think you can assume that if they don't know they own it they aren't going to get heavy about it.
