hi
there is another good programmer for 8051 family and 28** eeprom series here:
**broken link removed**
i have built it and its worked properly

 

the circuit for the easy downloader looks simple, but how come it uses a "pre-programmed" microcontroller to program another microcontroller?

its just like these:
q: what do you use to program a microcontroller?
a: a programmer
q: what makes up a programmer?
a: a microcontroller

???
 

you can use your friends programmer or you can spend some money and to program it by rented programmer.
but as i told you can use the above programmer that don't have any pre programmed micro and also can program the 28c** eeprom series.
good luck.
 

Did you check this new verison?
