Thanks to Stefan Schomburg, I have been able to add a copy of the ROM image for Toolkit 2 version 2.03 to my website. This is quite an old version, the list of version numbers implies it was the first version to be patched to fix initialisation problems on the MG ROMs. There are a few more recent versions on my website for use with emulators, this will mainly be for posterity and software testing with older versions of Toolkit 2. Download it from:
