MiniVNC Remote Desktop Server for vintage Macintosh computers #Retrocomputing

MiniVNC is a remote desktop server that has been written from the ground up for best performance on 68k Macintosh computers.

It was originally an experiment to see whether a Macintosh Plus could be controlled remotely, but has since been expanded to support color on all vintage color Macs!

The goal of MiniVNC is to provide better performance and compatibility with older Macs than ChromiVNC

It accomplishes these goals by:

  • Using Classic Networking (i.e. MacTCP) rather than Open Transport
  • Implementing a limited subset of the Remote Framebuffer Protocol, which favor of performance over full compatibility with all clients.
  • Implements fast but inexact screen change detection, favoring performance and low memory utilization while allowing for the occasional missed update and visual artifacts.
  • Written in C++, with optimized 68x assembly code where necessary for best performance.

MiniVNC is built on MacTCP and requires System 7, but it will operate on later Macs using Open Transport. MiniVNC has been developed and tested using a RaSCSI device operating as an Ethernet bridge, but should also work using a Mac with a built-in Ethernet port.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
