I recently returned to shooting 35mm again and came into an EOS-1 (1st-gen) which I've been shooting with my Nifty Fifty (fun!), but found myself missing the red focus dot and wanting an IS lens, specifically the EF 35mm f/2 IS and EF 100mm f/2.8L IS Macro.
So I've been thinking of upgrading to an EOS-1N to get my red dot back and saving up for this rather expensive (but soooo lovely) Canon glass, when I came upon this bit of info on :
Can anyone confirm this? If so, is this specific to 1st-gen EOS-1 only? I guess what I'm really wanting to know is: does IS functionality work properly with EOS-1N?

There are some minor compatibility issues with some early EOS cameras, but it is only under some specific conditions, and should not be a problem for you.
Here is a link to a Canon "Infobank" article which spells it out: Image Stabilization Camera Compatibility
IS lenses work with all EOS cameras, regardless of when they were introduced. The IS system − gyros, microcomputer and special lens group − is part of the lens, not the camera. However, there is some communication with the camera and there are some operational differences between the EOS SLR models.
We do not have full data for every IS lens/EOS camera combination. Before taking a picture, look through the viewfinder to check that the IS system is operating correctly (remember to allow up to 1 second for the system to start up after the shutter button is partially depressed). If there does not appear to be any increase in the steadiness of the image, or the image is jumping around in the viewfinder, there is probably an incompatibility. Movement of the image in the viewfinder immediately after an exposure is not usually a problem and will not affect the sharpness of the exposed image.
