This is a ZX Spectrum game. You can play it on actual ZX Spectrum hardware (this version is the 128K version with AY Music) but it can be loaded onto a 48K no problem, you'll just not get the music.

Robot 1 has been left behind by the crew who have abandoned the ship which is on a collision course with the nearby sun! Robot 1 needs to gather together the 4 teleport keys and then find the teleport pad to escape. You have 5 minutes before things start getting toasty. Keep an eye on your battery meter, if it gets too low, you'll need to find a recharge socket. There are many data keys to collect around the ship which adds to your score as well.
