Sinclair ZX80 / ZX81 / Z88 Forums

Umm...that's why I said it was a ZX80 program with modifications on the next page for the ZX81.

But there's no modification of line 200, which is why I needed Andy's help. Thanks

Thanks, I was vaguely aware of TL$ being recognised by the ZX80. There's no alternative line given for the ZX81. I think I have an early hardback edition of the book, later editions seem to have one page more. Maybe they corrected this? I'm still pleasantly surprised that the library had a copy. It ...

What I do remember is being the first "kid on the block" to own it And even more amusing, last weekend I found my original copy. After much perusing of adverts I chose Catacombs as my first 16K game and then 3D Monst...
