As an reader I like also to introduce myself:

in 1980 i build my first 8085-computer, first with HEX-Keyboard and
6 Digit-LED-Display later with b/w-monitor, ASCII-keyboard and floppy-discs running CP/M 2.2 - it has been a project of a german magazin (ELO) called "moppel".

My first microcontroller-project was a 8049 as an counter for agricultural equipment.
And an 8049 as controller for an activ monitor&keyboard-switch (8 PCs with one monitor&keyboard)

Another thing was an Pump-controller with an 8051.

Today electronics is just a hobby and i'm doing an Timer for a seeds-drying device (my father is a farmer) with an 8051 - not finished.

I'm 23h and my home is in the middle of germany (near Wuerzburg).
