I suppose NeXTStep OS 1.x with Display Postscript isn't freely available for emulation?

A classic Mac loaded with everything you'd want.

@methoxyf @rayckeith You can also run NeXTstep 1 (and others, including the 0.8 and 0.9 pre-releases) in the Previous emulator on which the Infinitemac NeXT emulation is based - https://previous.nextcommunity.net/
