I'm reasonably sure about these dates, but there is a margin of error as I am going solely on some gaps within old product literature as a reference.

I have a copy of this lens which I picked up on eBay for a bargain. I have in mind to figure out how to non-destructively mount it to a Canon EF mount while retaining full functionality.
The register depth is slightly less than the EF mount, which makes the conversion a bit more interesting. Also on my copy, there is a protrusion for the aperture gate which needs to be taken care of/removed, as it would slap into the mirror on a full frame Canon DSLR.
This thread on camerahacker.com discusses some of the issues involved with such a conversion.
In general, Minolta Rokkor lenses are well regarded, and I am excited at the prospect of having this work with Canon EF.
The -X Designation
The designation making this lens a ‘Rokkor-X’ has no real meaning, other than marketing purposes for lenses that were exported from Japan to US and Canadian markets. To the rest of the world this lens is known as the “Minolta MD Rokkor 45mm f/2.0″.

This Lens Is Alive! – Updated May 14 2010
The bad news is that I didn’t mount this on a Canon DSLR, but the good news is that I am indeed using this lens… with a very unlikely companion… the Canon PowerShot S400 point and shoot camera. I have the lens handheld in an inverted position in front of the camera. The S400′s lens barrel fits perfectly and snugly inside the first ‘ring’ of the 45mm’s front element. The Rokkor is fantastically sharp. Below are some shots I have taken with this dynamic duo:
