As the Dutch TV commecial says… “A little bit of myself and a little bit of… “. My Home-brew AT89C51 Eurocard SBC based on an old Elektor design with some extensions. Flash interface to support Atmel’s “Flip”. As well as some external memory so that also plain 8051 and 8031’s can be used. The AM29F040 is used as I had a whole pile of these.
