I've read his last message, and it sounds like he will be able to distribute his DIFFERENCE files. Forgive my ignorance, but what are DIFFERENCE files? How would they be of use to someone else? If I wanted to make these changes on my machine, would I have to type in the Rainbow's BIOS code and recompile it? Would I need an E-PROM to change the Z80 bootstrap loader code? I understand Suitable Solutions was undertaking a survey to determine what new products should be introduced for the Rainbow. One of the items was a 80286 chip replacement for our machines. Perhaps with the talents of people like Richard Thomsen, such projects could be realized. Hey, perhaps Richard Thomsen could join forces with Suitable Solutions to market such Rainbow improvements or even a new MS-DOS machine! Using DEC as his guide, he would be certain how NOT to market his machine. Since Suitable Solutions is already well established, such a joint venture might provide the best forum for Thomsen to get his ideas out to the Rainbow community. George
