Hi Doug, the cards are indeed PC coprocessor cards.  They are
described in the IIGS user's manual.  They were introduced
to the Apple II before the introduction of the IIGS, back in the
days of the IBM XT, so they are XT class coprocessors.

The color switch is a video converter and mixer.  You plug a
cable that hangs out from the back of the GS into the GS RGB
video port.  You plug an internal cable from the color switch
into the PC Transporter.  The connector that is MOUNTED
on the back of the GS from the color switch (not the cable,
the OTHER connector) is where you connect the GS RGB
monitor.  If your GS units did not come with RGB monitors,
it is possible to connect an Amiga Commodore RGB monitor.
The GS uses 15Khz analog RGB, like the Amiga.

The color switch converts digital CGA to analog RGB and
mixes the signal with the GS' own analog RGB.

Part of the emulation software lies not in the card, but must
be loaded from disk.  The software is on the ground ftp server.
...it is the emulation software with a bootable disk image
(of MS-DOS start up) to get you started...

     As Neil Parker points out (and as Dr. Tom informed me yesterday),
there is some problem with connecting via the DNS ('name') URL. You can
use ...
