Almost, Espen check www.lawicel.com (in Swedish), they have made a
'simstick' for Atmel 40pin devices, the AT90S/LS8535 has a 512byte 512byte
RAM and the 8kbyte Flash memory for the code. You can even get a finished
unit from Lawicel with everything it is 330kr($35). Note that the Simm100
can be used as a standalone unit or in the simmstick bus.

The fine thing about the Atmel's is that you won't need to get anything
exept the chip and board, programming is done with a passive LPT programmer,
only three resistors, they are even optional! Bascom AVR is availabel in a
demo version that is only limited to 2kbyte code. It has functions for
everyting from the ad conversions, eeprom memory communication, serial
communication and lcd output.

For you guys who can't understand Swedish I suggest that you get the stuff
from www.dontronics.com, you can also find information about bascom AVR
there and i think that you even can download the demo version. They also
have a shematic for making the passive programming cable.
