[comp.sys.mac.hardware] Sega 3D glasses document fix 1.1 now 1.2

jmunkki@kampi.hut.fi (Juri Munkki) (01/08/90)

This is patch 1.2 of the Sega 3D glasses interface document.  It
supersedes versions 0.9, 1.0 and 1.1 of the document. Version 1.2 is
available with anonymous ftp from vega.hut.fi [130.233.200.42].
pub/mac/finnish/sega3d/

Version 0.9 and 1.0 of the document have the TxD+ and TxD- pins
reversed. This causes problems only with my demo software and can
be noticed easily, because both lenses show the same image. Fix
this problem by pulling out the TxD+ and TxD- pins from the miniDIN
connector, swap them and push back in.

Version 1.1 (which is what you have after you make the previous
change) has the tip and center of the glasses connector switched.
Again this doesn't cause any problems unless you use the demo
software. The spiro and Macintosh demos will clearly be inside
the screen and their perspectives will look wrong. To fix the
problem resolder the connector or change the software to swap
the meanings of left and right. If you intend to write for the
glasses, it might be a good idea to include an option to switch
left and right.
