Prototype Twiggy Mac disks

I got a chance to work with some of those Twiggy Mac disks this week, and I made some pretty cool discoveries. They are actually MFS format, but they have 870K capacity. The MacPaint 0.5 documents will open in MacPaint 1.0 on the Mac 128K.

The resource fork has a few differences, though, so I wasn't able to get any programs to run... yet! But I was able to extract a funny icon from the System file.

Thanks for spreading the word about these extraordinary prototypes.
Did those 5¼ flexi disk drives also use variable rotation speeds?

Yes, the Twiggy disks used variable rotation speeds.

Nice. Were you able to boot the images OK in Mini vMac?

I was curious about whether they'd run in an emu.

No, the disks would not boot a Mac 128K. None of the programs will run on the 128K.
