Interesting print out
I bought a zeddy and found a printout in the manual.
What was interesting is that it looks like it does hi-res script from a purely BASIC program. Or at least I assume it is just the program and nothing else loaded. I don't have the time to type it in and test it!
Is the DATA machine code for the hi-res driver?

Re: Interesting print out
It looks like it's altering the SYSVARS for the character set, 23606, 23607 - so my guess is that it's a FONT in the data statements, rather than any machine code.There doesn't seem to be anything that would call any machine code in the program either.
Re: Interesting print out
Maybe you bought a Zeddy, but the program is made for a Speccy (ZX81 BASIC does not have DATA, READ, RESTORE commands).Lardo Boffin wrote: ↑Thu Jun 22, 2017 2:54 pm I bought a zeddy and found a printout in the manual.

That would explain it - I have never programmed in ZX81 BASIC so wouldn't have spotted that!siggi wrote: ↑Thu Jun 22, 2017 3:12 pmMaybe you bought a Zeddy, but the program is made for a Speccy (ZX81 BASIC does not have DATA, READ, RESTORE commands).Lardo Boffin wrote: ↑Thu Jun 22, 2017 2:54 pm I bought a zeddy and found a printout in the manual.

I may have to change the title to not very interesting...

Re: Interesting print out
100% certain its for a spectrum , not only because of read data and restore statements, but the lower case letters and use of the poke to change character font !
Re: Interesting print out
and from the address used for the 'font file' , written for a 16k machine...

Re: Interesting print out
There we go. Definitely not interesting then!
Although I don't mean that as abuse towards the Spectrum!

Re: Interesting print out
Yeah, never mind the : used for multi-statement lines... which is not available on the ZX81, but is available on the ZX Spectrum
Don't worry about it. Bits and pieces of different computer systems often get mixed together. I have a key top from a keyboard that I don't recognise that arrived with something...
Manuals for add-ons for who knows what, that never came with the computer that I got.
Even some Plus 4 joysticks (although they did just come with various other joysticks).

Re: Interesting print out
By the way, if you wrote a suitable program, it was possible for the ZX81 to print lower case, or even your own UDG on the ZX81 / Alphacom 32 Printer / Timex Sinclair 2040 printer.
