Easy-Downloader V1.1 with SDCC

The hardware has a bit change at rs232 level converter. Now the circuit uses a popular rs232 level converter, MAX232. Also I cut the bridge diode at the DC input, now I use only one diode to prevent wrong polarity of a given DC adapter. 18 March 2004: found hardware schematic error at MAX232. The error is that pin 2 on the D-SUB 9 connector must be connected to pin 13 on the MAX232, not pin 8. The error had reported by Henrik Olesen, student at the University of Southern Denmark.
