My 20D reminds me of this camera, and there is a good reason for that. The T90 was I beleive the prototype for the EOS line. It was part of the FD line, and used FD lenses, but it appears to be the first version of an EOS camera. It had multi-spot metering, and even though it had a three motor system (film wind, rewind, and shutter) it had the least vibration of any camera. Without mirror lock it produced very stable sharp images.
