Today I was working on a very nice 1995 vintage SPARCstation LX with CDROM and QIC-150 tape drive (3 lunchbox type units). I was trying to install a newer version of NetBSD on it than was already installed. The stack of 3 units was stored in a museum grade glass display cabinet. Sadly all 3 units have a small degree of yellowing but more importantly the plastic cases have become very brittle and bits just break off with minimal mechanical strain.
Is there any process to reverse the brittleness which could be used to preserve the cases? Thanks Tom Hunter
