 SGI - PS/2 keyboard and mouse converter
 =======================================
 
+Progress: prototype board completed, firmware not done.

 About
 -----
 This project is a converter for connecting PS/2 keyboards and mice to old
 Silicon Graphics computers which had a proprietary keyboard/mouse interface. It
-should work on:
+should work on every non-PS/2 SGI computer with mini-DIN6, DB9 and DB15
+keyboard/mouse connectors, such as:
 
-  - 4D series machines
-  - Indigo
-  - Crimson
+  - Iris 4D series
   - Onyx
+  - Indigo
 
 This converter is not necessary, and will not work, for any later SGI machines,
 like the indy, O2, indigo2, Octane, and so on, because they use PS/2 keyboards
 and mice directly.

 SGI signalling and protocols, see the copy of the keyboard and mouse manpages
