Steve, you and me must be of the same generation

I started with the Sinclair ZX81 (I think it was called the Texas 81 in the US ?) - was amazed that you could get a full "traditional" startrek game with an 8 x 8 galaxy, black holes, bases etc all in 1K of memory !

As for the audio tapes, I remember playing them on a hi-fi and you could hear the actual pitch changes representing the 1's and 0's - baud rate of about 10 I guess
