Depending on what RAM board you have, you can probably expand the RAM up to 16Mb.
Are you sure that it uses 72-pin SIMMS though? I've only heard of 30-pin SIMMs in these computers -- that's what my TT and STFM use.
It may be worth taking the top off your computer to check what type of RAM it uses and to jot down the serial number on the RAM board. You could do a web search on the serial number and find out a bit more info. That's what I did before upgrading my TT's RAM.
I have 4 x 4Mb 30-pins I'm selling for a fair price if they're any good to you.
