As popular as the 15-1994 is, people often buy it only to discover the code they need is not in it, this is because many device codes had to be dropped to make room for all the extra Optimus/Realistic codes that Radio Shack supports.
To this end, I have created a cross-reference list of OFA device codes which shows if they are in either the 15-1994, the Cinema 7 (URC-7800 version) and the Producer 8 (URC-9800 version). This is based entirely on the code lists from the manuals, so there could well be errors. I spotted a few typos in the Cinema 7's list for example, and the 15-1994 manual makes no mention of cassette codes. As time permits, I will try to verify some of these codes. As I find device codes that were not mentioned in the manual I will add them to the list.
Eventually, I hope to add the actual infrared protocols to this page.
