The 16 bit version consists of three parts, the 8 bit version only of two. I've played the PC and Spectrum versions. The Spectrum version contains less random elements and is much easier to play (especially concerning the fight against the Vesucos). Therefore I consider Part 2 of the PC version being unplayable because in the Combat Panel you won't get a chance to react fast enough before the energy of your shield reaches zero.
