Brittle plastic

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

Is there any process to reverse the brittleness which could be used to
preserve the cases?
