Wrote up a little blog post on the GlyphBlaster. Nothing you haven't seen if you've been following me, but just putting it out there.

really happy to have discovered something hiding in plain sight for several years: robyn & rand miller's original Myst pitch document from 1991.

it's a succinct work of art in itself. i'm surprised at how much of the world design was already on paper.

as all of the copies found elsewhere online are heavily compressed webp/jpeg, i've uploaded the robyn's original PNGs to IA here:

Thanks to contributer demik, Snow can now print from your emulated system to a PNG, using an emulated Apple LaserWriter IISC!

To try it, grab the bleeding edge build and check out https://docs.snowemu.com/manual/printing on how to set it up

The reverse engineering effort is written up here: https://68kmla.org/bb/threads/laserwriter-iisc-scsi-protocol-reversed-for-emulator-implementation.52165/

Oh wow! The newly released version 1.4.0 of the Snow Macintosh emulator now even runs on a Raspberry Pi Zero 2. Previous versions only showed a black screen.

It comfortably fits into the 512 MB of available RAM, using about 50-60% of it. The downside - two CPU cores almost pegged to 100% still only result in about 1/3rd real world speed for compact 68000 Macs (emulating a Mac Classic or Mac Plus in my case). This is slow - considering how slow these machines already were.

But hey, it works!

Thanks to contributer beholdnec, Snow now supports bin/cue CD images and also audio CDs!

This allows, for example, for playing 'Battle Chess: Enhanced', which uses CD audio for music and sound effects, in all its full glory.

These new features are now available in bleeding edge.
