Damn
I feel your pain! I had a similar situation also in the early 90s.. My dad was cleaning up and wanted to throw away some disks. I pointed to a box of all the educational software we had, but somehow he threw out another box of disks - _EVERYTHING_ I ever programmed, the BACKUPS of the same, all the drivers and backup drivers for all my hardware, and all the archives of BBS related stuff. I didn't realize it until weeks later when it was too late and that made me put my remaining software and the atari on ice, while all of my hardware (rverter, voicemaster jr, computereyes, parrot, hybrid arts midi, atr8000 and loads of other stuff) I threw into my electronics junkbin, where they got cannibalized. Years later I got all my drivers back and reconstructed what was left of the hardware, but life will never be the same without my programming stuff.. I've had dreams now and then that I found the missing disk case, hidden in the house, or while looking around a junkyard.
Anyways, I wish you luck! Your situation sounds a tad more hopeful than mine.
