The CRAY used UNICOS which was POSIX compliant and so BASIC could have been compiled for it. But yes, BASIC was never an “out of the giant box” language.

`store` and `load` implemented, using #JupiterAce code, as it is more robust than ZX-Forth original. This means you cannot load screens from #ZX81, though you could load screens into Ace Forth (if you can think of a use for that). With that done, I can now start coding! #minstrel4th #retrogaming

I had a PYE B&W TV too, though not like that. I remember it had a rotary tuning dial. My gran gave it me. Used it on my ZX81 and Spectrum. Parents were reluctant for me to plug it into the big colour TV, though I did sneak it down occasionally.

I, like many other started with the good old ZX81, on to a Spectrum and showed some interest in computers at work. Ended up being the DP manager working in an arcane language called DACL and DOS commands, then onto IBM system 36 /38 before getting fed up being inside and left to drive lorries..
