Well, I got the entire package with my MDS 220 system.  All the manuals,
all the software including version update disks throughout development
of whatever it was used for, even what appear to be most of the recipts.
 I hope to eventually use it for some 8051 development (there's even a
box of spare bond-out 8051 chips for idiocy while breadboarding and
blowing out the ICE).

I even have a tube or two of (historically unobtanium) 8243 chips so my
'expanded mode' designs with the 8031 can 'pretend' to be a regular 8051
with masked ROM code.  I got a bunch of 8032 chips just last month. . .
