Sinclair ZX80 / ZX81 / Z88 Forums

Here in USA, the ZX80 was the first Sinclair product I heard of. From the advertisements I realized a real computer could be obtained for $150 or so -- although I did not have $150 being a high school student. After running it though my mind for weeks i became convinced it was too limiting. So when ...

PRINT 20-2*3**2+4/2*3 This is a good brain-twister Using my 1970s learnt order-of-operators, it all works out fine but this new PEMDAS idea messed with my head.

however it returns a FATAL error. Any ideas?

the include file has one line: that works fine if it is typed into the ASM file directly

Yes it is supported, I see now it was user error in my script. Very nice work on EightyOne

Cheers to Bob, it looks right at home on the ZX81 screen

And cheers to the original designer Ahmed. As a game it is difficult, but I work at it a few minutes every week and have progressed a bit. I'm still not sure what each icon represents yet sure it will become more clear in time

Very nice. I examined the keyboard article "Change the meaning of the keys on your keyboard" -- it was very informative. I transcribed the original text of the article. Can it be added to the type-in files?
