For sale is an old board made in between 1993 and 1997. It has the i51 MPU, ROM, and RAM installed in DIP-sockets. I can provide several ROMs containing Intel BASIC51 (sort of gw-basic with floating point), and other firmware units.
This board is fully working and comes with documentation.
It's currently located in Denmark, but I am going to go there to stay for a couple of weeks so probably I will bring it to Italy when I will come back.
I am looking for 50 euro + S/H. If interested, or for question/info, contact me in private.
