Where it runs

Everything NeuraWeb writes for a Commodore loads from a real floppy and runs on the real machine. Each machine gets what it can carry; nothing is promised to all of them alike.

Commodore 64The full desktop, from a 1541 floppy. Built for 64K of memory and a 170K disk.
C64 UltimateThe same, with the Ultimate's extra memory and its network.
Commodore 128A fuller version: more memory and 80 columns.
VIC-20 and PETSmaller, text-only versions where a desktop will not fit.
NEURA/8In the browser, on the exact machine, with nothing to install.

Every release is tested twice: on NEURA/8, and on a real C64 Ultimate and 1541s before it ships.
