a time and I get errors only in one bit through 3 bytes at least?The raw encoder count is only 16 bits so the if error is always a MSB due to cable characteristics, the next smaller encoder difference is only 128 counts so would likely not be noticed.

Sounds like errors in the EPP connection. I would try shortening the EPP cable to the minimum length (If you are using a flat cable) or if you need a longer cable, use a IEEE-1284 compatible cable and a very short flat cable adapter to the 7I43s header. Might also be a marginal EPP port on the Motherboard. Peter Wallace Mesa Electronics
