pinouts and scancodes for Symbolics kbds

Folks --

I am involved in yet another attempt at a Sybolics keyboard
adaptor -- YASKA? ya4ska? -- and the project is in need of
some info.


1. Pinouts. Bolics kbd uses a 6pin connector, but I am told
that most old kbds only used 4 wires. For example:

  1- Power
  2- Data
  3- Clock
  4- VCC

The actual pinouts for the Bolics would be useful. Are the other
two wires used, and if so, for what?


2. Scancodes. I assume that on-board processing in the kbd
converts key presses/releases into codes which are sent to the
kbd driver. Would be handy to have a table of the resultant codes
from each press/release for all keys.


tnx,
-f


PS If success for this latest adaptor project, slug list
will be first to know.
