Re: Transwarp GS question...

After almost snapping a couple pins off my TWGS CPU plug, I have to concur.
Mine have become permanent fixtures in the motherboard.  If I want a
motherboard without a TWGS, then I will buy a GS CPU for $10 on ebay rather
than risk damaging a potentially much more costly component by removing the
plug!  Funny how the peripherals value more than the CPUs nowadays...
