== Software ==
Supported by "Starwriter".
== Similar (or identical?) Interface ==
The circuit is very similar (or possibly indentical) to the [[Tim Riemann's RS232 interface]], both circuits are using a Z80 STI, both mapped to the same I/O port addresses. Whether or not the circuits are fully compatible with each other is '''unknown'''. Some small details might differ. For example, the clock source being passed to the Z80 STI chip could be different.
