VNCview GS 1.0b1 README
VNCview GS 1.0b2 README
VNCview GS is a Virtual Network Computing client (viewer) for the Apple IIgs. You can use it to display and interact with the graphical desktop of another computer through your Apple IIgs.
System Requirements
A (real or emulated) ROM 01 or ROM 3 Apple IIgs
Apple IIgs System Software 6.0.1
Marinetti 2.0 or later, with a functional TCP/IP network connection
Apple IIgs System Software 6.0.1 or later
Marinetti 2.0 or later (latest version recommended)
Andrew Roughan's Crypto Tool Set (needed for password functionality)
A computer running a VNC server to which you have access

VNCview GS will generally perform best when connected to the VNC server through a high-bandwidth, low-latency network connection. A IIgs connected to the network via a high-speed network connection such as a LANceGS and a server connected to your LAN will probably provide the best performance.

Usage
To start VNCview GS, simply run the "VNCview.GS" program. The New VNC Connection dialog box will be displayed, allowing you to configure and start a VNC connection.

"View Only Mode" allows you to see the server's display but not to send any keyboard, mouse, or clipboard input to the server.
"Allow Clipboard Transfers from Server" indicates that the server is allowed to send its clipboard contents, which will be transferred to the IIgs clipboard.
The "Preferred Encoding" is the method that will be used to represent pixels on the server's display when sending them to the IIgs; the available options are Raw and Hextile. The Raw encoding sends lines of pixel values to the IIgs, while Hextile represents the display as a collection of small rectangular areas. One of these methods will likely be faster than the other in your configuration; the best way to tell which is faster for you is to try out both. In general, Raw encoding is best for relatively high-bandwidth connections like Ethernet, while dial-up modems and other low-bandwidth connections may give better performance with the Hextile encoding. Some servers may not support Hextile encoding, in which case Raw will be used regardless of this setting. VNCview GS also supports the "CopyRect" encoding regardless of this setting; it should always be faster than both Raw and Hextile but can only be used in limited circumstances.

The Raw encoding sends lines of pixel values to the IIgs, while Hextile represents the display as a collection of small rectangular areas. Raw is generally faster than Hextile in the current version of VNCview GS, but Hextile may be faster on slow network links. Some servers may not support Hextile encoding, in which case Raw will be used regardless of this setting.
When you have configured your new VNC connection, simply click "Connect," and if all goes well you will be connected to the VNC server. You can interact with it with the mouse and keyboard and scroll your view of its display. The option and Open-Apple keys are sent as "alt" and "meta," respectively; their exact interpretation depends on the server. Keyboard shortcuts for menu items are disabled when connected so that these key combinations can be sent to the server. Select "Close" or "Quit" in the File menu when you are done with the connection.

VNC Server Interoperability
VNCview GS should be able to connect with any VNC server that fully implements the RFB protocol as published by RealVNC Ltd. or its predecessors, though in practice it seems to work better with some servers than with others. Here is a list of some VNC servers for widespread platforms; many others are also available.

Troubleshooting
If you are experiencing problems, it may be helpful to try removing, rearranging, or even adding system extensions. This may eliminate assorted problems associated with Marinetti and its interaction with other components of the system. Upgrading to the latest version of Marinetti (3.0b1 as of this writing) may also be helpful.
x11vnc is a good option, because it supports server-side display scaling, which is useful to fit more information on the IIgs screen.
If these steps fail to resolve your problems or if you have other questions, comments, or bug reports, I can be contacted at SHeumann@myrealbox.com.
VNCview GS does not work with the Screen Sharing functionality in OS X, because the Screen Sharing server does not support the pixel format that VNCview GS requires. The above servers can be used instead.
