A native Mac IDE for ZX Spectrum with tools from the future.
Create, build, run and debug Sinclair BASIC and Z80 projects for ZX Spectrum 48K and 128K in a professional native Mac IDE.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
