3 were made, 1 blew up on launch, 1 was scrapped just after launch and the other......... i think that blew up too but i cant remember for sure.
story has it iirc that the 2nd one wasnt scrapped but was bought by an eccentric billionaire who kept it in a secret collection of rare and unique ships in an asteroid belt somewhere.....**** Obviously none on that was in the original game, it was just fluff lore, but that was the cool thing in the original game. i lost loads of time looking for generation ships and space dredgers on my spectrum (I think by the time i got it on the amiga i realised it was all nonsense and not in game - tho the amiga did have the constrictor i think it was called, experimental ship that you could get in a unique mission late in the game ....... didnt that even have a cloaking device? (i may be making that up) but either way it was tough as nails.
So much cool lore in the old games... i would dearly love to have tionisla grave yard in elite dangerous
***maybe not totally accurate, i could cheat and google but where is the fun in that
