I'll take the cover off the machine again (it's not my internet machine) and re-check the RAM. It has currently two banks filled out from three and reports 16MB when started. Each bank has two SIMMs in it, so I assume they are 4MB SIMMs.
So, can I actually put in the third bank SIMMS of larger capacity, say 16MB so as to double the memory.
