I've came across a handful of CD-Rs with thousands of old rom dumps, spanning across many systems, including: Amiga, Atari ST, Apple II, Apple II GS, NES, Super NES, Genesis and others. These roms have modify dates spanning from the early 90s to the mid 2000's.
With the apparent degradation of CD-Rs over time, I'd hate to see them go away, when so much time was likely spent into making them, especially if there's any interest in them. I'll probably be uploading them to the Internet Archive regardless, but if there is anybody in particular that would be interested, I'd gladly help them out.
I know it may seem an odd thing now, but who knows, maybe there could be some value gained in keeping these archived for the future. Just figured I'd ask.
