Re: LOWRES -demo
Dr Beep, your ZX81 work is truly inspiring! Your new approach got me thinking and I've came up with a twist on your original idea and put together a simple 1K demo. I hope you like it! LoHiRes.p Wel done, you are close to my current idea in the display so I am gonna take a look in your screen.

Re: LOWRES -demo
It's a very interesting new technique. As an optimisation, you can replace the two instructions LD H,D and LD L,E with single instruction EX DE,HL to achieve the same effect but using 1 less byte per row. That was my first try too, but now try printing 2 lines of telephone, then you get an errordis...
