I am thinking about upgrading an old 486DX33 with 30 pin simms. I have no
manual or identification for the board.
I have a Intel 486DX2 66 that I am thinking of putting in it. I know the 33
and 66 run at the same clock speed so any DX33 should be able to run a 66
without any changes....right? This has a CPU board that isn't a Ziff
socket....I haven't replaced one of these yet......how much or a pain are
these to upgrade? Do you just manually pull them out and push them in....or
is there a trick to it?

The 30 pin memory array is the usual 8 slots.....at present there is 1 meg
in each slot. Do all 30 pin setups allow for mixing the groups of
four.....can I leave 4 megs in and replace 4 with 4 meg 30 pin simms or do
some 30 pin boards require particular memory configurations.

Thanks

Mark
