Mr. Jalkio, you don't know what you are talking about.

The A3000 is upgradeable to 18 Mbytes on the motherboard, no slots are used
or needed for this upgrade.  No simms are used or needed.

You take the 1Mbyte of ram out of the normal memory section of the
motherboard and stick it in the display ram area with the other Meg that
is already there (the machine comes with 1 meg 'chip ram' and 1 meg of
'fast ram').  This upgrades your 'chip ram' to 2 Mbytes.  Then you take
up to 16 Mbytes of 1Mx4 bit drams (in 4 Mbyte increments) and you plug
the discrete chips into the empty sockets provided by Commodore on the
motherboard.  You now have 18 Mbytes.  That is all there is to it.  There
is no need to "throw small SIMMs away".  There aren't any in there.
