<h2>About vnIIc</h2>
|
|
<p>
|
|
The name "vnIIc" is a play on <a target=_blank
|
|
href="https://en.wikipedia.org/wiki/Virtual_Network_Computing">VNC
|
|
("Virtual Network Computing")</a> and the <a target=_blank
|
|
href="https://en.wikipedia.org/wiki/Apple_IIc">Apple IIc</a> for humor
|
|
purposes, but the application does not use the VNC or <a target=_blank
|
|
href="https://en.wikipedia.org/wiki/RFB_protocol">RFB</a> protocols.
|
|
Apple IIc is a trademark of Apple Computer, Inc. VNC and RFB are
