Legal Stuff
The pictures are stolen from Wolfsoft. I have written to them but they don't respond. So I will use the pictures until they write me that I must delete them ;).
Getting the Chips
RAM
I found Memphis AG which offers 512Mbit (64MB) RAM Chips for about 18 Euro each. So you will get 128MB RAM.
Here is the datasheet:
Flash Memory
But why only increase the RAM up to 128MB? One 32MB SD-Ram Chip costs less than 5 Euro. So you could mod a SL4 to 64MB for less than 10 Euro. Getting the 128Mbit (16MB) Flash Chips to upgrade a CL4 class SIMpad is also possible.
Bigger (256Mbit - 32MB) chips are also available but very hard to get. The 16MB chip costs about 9 Euro (Memphis AG).
The Flash chip is easier to add because there is no need to remove a chip first you "only" need to solder the chip in SMD ;).
Looking at the pictures
The card reader plastic needs to be removed.

Getting build in service
Wolfsoft offers this service for about 190 Euro inkl. chips.
But Memphis AG the chip distributer knows also cheaper service companies.
To do
- Buying some chips and do the mod?
- Do detailed discription about how to get rid of the old chips without killing the SIMpad
