Hot on the heels of the Speccy emulator, is an emulation of the Spectrum's older brother, the ZX81. It uses the same VB core as vbSpec, but due to differences in the display hardware and processor speed of the ZX81, this will run happily at full speed on just about any PC that is capable of running Windows at a usable speed.
