The things we keep around for years, without being able to 
disassemble them or throw away....
Like if they were embalmed in Haitian protection spells. LOL
I still have two expansion boards for the old Mac 512. they are 
called expansion boards, upgrading the machine to a whopping 
MEGAbyte, but are actually complete new motherboards. Still brand new 
and in box, totally worthless, but for some reason I could never 
trash them.
Well, maybe twenty years from now a collector will go nuts and offer 
me his Rolex for it. More likely, I will find a chip on it I need and 
finally kill them.

Do you use the slide-a-wire-under-them method?

Some have great power supplies; others a nice silent fan to place 
next to the bed on hot summer nights. :-)
Usually, the most valuable things are all the different types and 
sizes of machine-screws, the brass and anodized ones you can't get 
from the hardware shop. I have quite a collection of them and they 
have saved the day more than once.

Hmmmm... now you've made me curious. I have this - working! - Nixdorf 
8810 "portable" (15kg).
Built and shaped like an old scope, with the keyboard in the lid, a 
built-in small green monitor and... a thermal printer. Latest 4.77 
Mhz technology! 256 Kb of portable power for the successful 
businessman. :-)
The chips in there must be hand-engraved and signed by Fred 
Flintstone personally.

But I'm rambling too now .... very un-vcf-related, all of this.
