Intellivision reset switch

[Jules Richardson]

Can anyone who's been inside an Intellivision confirm that there's supposed 
to be a little foam disc beneath the reset switch plate?

I picked a system with a box of cartridges up earlier, half expecting the 
machine to be dead (I was figuring it was going to be a blob of 
easily-dead-after-so-many-years custom logic inside, but it's more like a 
"real computer" in nature). It *was* dead, but the [initial, at least] 
issue seems to be that the reset switch consists of a metal plate which is 
supposed to make contact with the PCB when pressed - and presumably is held 
away from the PCB by something when at rest. Except that there's no 
"something" in this machine - with the machine the right way up, the plate 
is free to contact the PCB, holding it in permanent reset.

I'm guessing it was a blob of foam, which has deteriorated, but maybe it 
was a metal spring, or a piece of u-shaped plastic etc.

cheers
