True, my bad.
I had my Mac_II running with a MC68030 and MC68882 for so many years that I mixed things up.
Of course the stock cpu was a MC68020.
Personally I doubt that Paul C. Pratt will add a MC68030 emulation in MiniVMac II in the foreseeable future, same for a larger RAM assignment.
Not sure what you want to magnify - larger screen or enlarged pixel?
I could manage to build a few wide screen flavours, but don´t need Magnify or Full Screen.
For the Macintosh II emulation, these options specify the resolution of the external monitor, and shouldn't cause compatibility problems, at least if you choose values that were common on real monitors of the era. On the other hand, the Macintosh II emulation is unfinished, and not really usable yet.
Some example screen sizes:
common old Macintosh screen sizes
-hres 512 -vres 384
-hres 640 -vres 480
-hres 800 -vres 600
-hres 1024 -vres 768
common current screen sizes, but divided by two, so can use Magnify in full screen
-hres 512 -vres 384 { half 1024 x 768 }
-hres 640 -vres 400 { half 1280 x 800 }
-hres 640 -vres 512 { half 1280 x 1024 }
-hres 704 -vres 450 { half 1440 x 900, width constrained }
-hres 832 -vres 525 { half 1680 x 1050, width constrained }
-hres 960 -vres 540 { half 1920 x 1080 }
-hres 960 -vres 600 { half 1920 x 1200 }
The Magnify feature was described like this:
Full Screen Mode
-fullscreen 0 { (default) start with Full Screen Mode off }
-fullscreen 1 { start with Full Screen Mode on }
-var-fullscreen 0 { Full Screen Mode is constant }
-var-fullscreen 1 { (default) Full Screen Mode is variable }
"-var-fullscreen 0" combines with -fullscreen like so:
-var-fullscreen 0 -fullscreen 0 { Never run in Full Screen Mode }
-var-fullscreen 0 -fullscreen 1 { Always run in Full Screen Mode }
In both cases, the "F" control mode command disappears.
Magnify
-magnify 0 { (default) start with Magnify Mode off }
-magnify 1 { start with Magnify Mode on }
The magnification factor can be changed:
-mf 1 { disable magnification }
-mf 2 { (default) 2x }
-mf 3 { 3x }
-mf 4 { 4x }
...
Disabling magnification with "-mf 1" removes the Control-M command.
My guess is that most blown up screen sizes will be blurry, I try to avoid that.
With SheepShaver/Basilisk II I could set the screen to my native display res. 1600X900 and run full screen.
No idea if this works with Retina displays just as well.
I usually want the dock visible, same for removable drives, so I go with 1300X700 most of the time.
