Hi Bill, Yes, you can use the same REX in a model 100 or 102.
If they are mod100/102's have the same amount of memory you will have no issues with stored RAM Images, but if they are different you will get a memory size mismatch when attempting to load them. Easy to fix using the file browse feature and creating a new Image though.
