The RomUpd card and program are now working very well, and all future SR-4's, RM-6's and dedicated systems will have it fitted. This week I was adding a user request to the software and used it for debugging the program. There is nothing like using a program to work out the wrinkles. The installation is also easy as only four connections are made to the processor board with NO track cuts. Just be careful not to lose the screws!
