Works great; the PEEK is to determine which type of video adaptor is on the system, they then use the BLOAD to directly load to the screen either a monochrome or CGA image file. I no longer have the simple mods that I initially made, but only a combined file with some added capabilities. The basic (sorry!) problem is to eliminate the CHAIN command in line 1510 by merging the two files (after renumbering one or both under GWBASIC). As for the data flow to the watch from the program, I did look at the data and it was recognizable, but I really don't remember the format. It shouldn't be too hard to use any standard ASCII (text) editor to edit the data file, and use only the part of the program that reads the data file and updates the watch (around line 7615 in RC1000.SYS).
