Hello Marko, Tuesday, 3 August 99, you wrote: Marko> True, but I think I'll try to build the universal cable.

Would you also interested in diskcopier prg for 1541->C64/C128/C65->PC (I just remembered that sometime ago I promised you send it). >> At least you can connect all commies at once to one PC and serve all >> at once.

You can use switcher or something similar if you lack of ports. >> http://easyport.hypermart.net/cable.gif Marko> The schematic diagram doesn't mention the resistor values.
