15$ is about the prize of the parts, I think. I got one built for about 30$,
so that's all I can say.

Here is the information:

The pure cartridge contains nothing more than a ACIA 6551A, a crystal
(1.8432 Mhz), and a MAX232.
The software uses the non-maskable-interrupt for data receive, the location is
at $de00.
A real advantage: disk drive, printer and rs232 can be used at the same time.

This is really true.
