µvMac (micro vMac) is a simple, configurable emulator for early Motorola 68000 based Macintoshes. It was forked from Mini vMac v36.4 by Paul C. Pratt, which was forked from vMac by Philip "PC" Cummins.
This fork was created to clean up and modernize the code base, make the project easier to compile and hack on, and allow for much easier user configuration. The intent of Mini vMac was to create a "emulator collection" of many very optimized "variations" of the same codebase. (See this article I wrote for more information.) I consider this much more trouble than it's worth, and intend to focus more on maintainability and accuracy.
µvMac is currently very early in development and is not ready for release, but its source code is publicly developed on Github.
Here's µvMac running on Linux with the default palette, emulating a CRT's natural colors. (This may be tweaked some.)
Here's some screenshots showing the configuration file modifying the system palette.
The below image, as well as the very first image on this page, are mockups of a possible upcoming feature, the configuration manager. This would replace Control Mode in Mini vMac, and would also appear when you start the emulator.
The configuration manager will require resources from a ROM. Here's the screen you get when you start up for the first time, without a ROM.
Supported Macintosh models
Currently, µvMac is very early in development, so only the Macintosh Plus is officially supported. Soon, the following systems are expected to be emulated:
- Macintosh Twiggy prototypes
- Macintosh 128k and 512k
- Macintosh Plus
- Macintosh SE
- Macintosh Classic
- Macintosh II
After that, µvMac will attempt to support these systems:
- Macintosh Classic II
- Macintosh Color Classic
- Macintosh Portable
- Macintosh SE/30
- Macintosh IIx
- Macintosh IIcx
- Macintosh IIci
- Macintosh IIfx
µvMac absolutely requires SDL2. There are no plans to support platforms that SDL2 does not target. For 99% of users, this should not be a concern. Dropping support for esoteric platforms and exclusively using SDL2 vastly simplifies the complexity of the code. (If there is enough demand, I may re-implement SDL1 support as well.)
Here's an incomplete list of platforms that can, in theory, be targeted. These are listed in order of support.
Development occurs exclusively on Linux and Windows, so those two operating systems are the only officially supported ones.
