The IBM Model M shell is made of what kind of plastic?

IIRC, Unicomp cases are made of a blend of ABS and PVC. I think IBM/Lexmark ones were too, although there was some speculation that they changed materials at some point.

Does that applies to M2 series as well? Looks like the made big cost reduction on the M2 shells

Old school IBMs are ABS. Unicomps are stamped PC/ABS.

Try boiling a IBM shell. It ain't pretty.

I should boil a Unicomp shell sometime.

Thx for the information. My religion does allow me to burn keyboards :yuck:

I think M2 it's plain ABS.

BTW, this time the keyboard science have to wait, i don't believe anyone wants to open and reassemble an M2 just to see if stamp is present..

It's likely the most hideous keyboard ever to dismantle and reassemble.

Keyboard freaks you know

Some people use to open and reassemble macbooks, and believe it worst than any keyboard :-)

I disassembled an M2 a long time ago, and I have vague memories that it might have been all-PVC. I don't really remember for certain though.

Is it written somewhere in the inner shell the kind of plastic used? I have an M13 and I can look for that legend

The kind of plastic indication is meant for recycling purposes, so is enforced only on reasonably recent plastic items, in the older ones is not said that this indication is present.
