can't help with the quest I'm afraid, but, for me, it is truly fascinating to see how far the program has evolved over the years.
I was messing around with MC versions 9.0 and 9.1 a few weeks ago, which was... interesting

JRiver's Nikolay posted this image of MJ v1.0.352 a few years ago...

suggesting that there may well be a complete set of install programs deep in the JRiver archives...
and I found this screenie of v5.0.601 (601!!! man, that must have been one helluva beta cycle!!)
