== Intro ==
This interface was originally described in the book "[[Maschinenspracheprogramme und Hardware-Erweiterungen für Schneider CPC's]]" written by [[Paul Bauriedl]], released by IDEA Verlag in 1987. Around mid-nineties, Tim Riemann has circulated the schematic as GIG in the internet.
The circuit is very similar (or possibly indentical) to the [[Schneider 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.
