Sinclair ZX80 / ZX81 / Z88 Forums

I once had a yellow folding reference card with a lot of info on the ZX81 such as Keywords, assembly code and timing and the character set. Does anyone have a jpg or PDF of this card? Thanks

Yes that was the most useful reference card. I used it every time I used my ZX81, for 30 years until last August. I moved overseas so gave away all my ZX81 stuff.

The Reference Card for programming.





Also useful was a hand-drawn copy of the keyboard layout.

Here is a PDF version of this card!

Cool!

Is it possible to scan at a higher resolution? Some of the small printing cannot be read.

Whoops! Sorry about this one! I didn't recognize that the card has small font printings. I will check my scanner's spec'. Thanks, mrtinb.

mrtinb and somebody else,

Please dispose the first file which I put on at the top of this post. That file was set for the 96 dpi. It was too fuzzy to read on the screen.

Now try these files with the 300 dpi result.

Oooo! That's much better. Thank you

Pretty much better, thanks for scanning.
