Does anyone know anything about this machine? When and where it was manufactured, etc?

Apparently the machine is an Apple ][ clone, called "BOSS-I". I have an instruction booklet for the keyboard and there they show, how to connect it to an ordinary Apple. The keyboard has some function-keys and some other nice features (one key Applesoft commands, for example).

The main board has both 6502 and Z-80 installed. There are seven slots, tape in/out, composite out, keyboard connector and some strange switch on the back panel. Only markings I could find from the board were "500AW" and serial#.

If you can give me any information about this machine or would like to know a bit more about it, please write to pasi.loytty@iki.fi
