Re: BASIC Programming Manual WOS.org

My speccy manual is third edition no ring binding, so as you have the full set, mark it's probably best if you could help Charles out as mine doesn't seem to line up with his chapter headings and to be honest after looking at the pics posted I'm not really sure whats needed. :oops:

Re: BASIC Programming Manual WOS.org

Hi Charles.

I have revision three of the book and it doesn't line up page or chapter wise with yours and to be honest after looking at the pictures you've posted I'm not really sure what it is that you're after so i'll leave this one to Mark who I assume has edition two.

Re: BASIC Programming Manual WOS.org

OK Charles no problem, but the the pages listed for the three chapters don't line up in my Spectrum manual,which is identical to the one pictured, so can only assume error on the transcribers part. The pages in my copy are chapter 25 127-130 chapter 26 131-133 and appendices 135-141 Will have to era...

Re: BASIC Programming Manual WOS.org

Which Speccy version Charles?

If it's the plain 48k version then all that those pages refer to is a binary to hex conversion chart then the book index itself, nothing of worth missing but I'm happy to scan if you really want it. :D


Regards.

Re: Interrupts on ZX81

Well both NMI ( non mask-able interrupt ) and INT ( mask-able ) are use for video generation so whilst maintaining a display polling is your only choice. so what are the options without display running ? INT would be difficult to use but perhaps technically possible first problem is int is hardwire...

Re: Third party keyboard

Yet another one for on the ZX81 membrane keyboard. Bought in Utrecht in 1984. I don't know who made it. That is a Filesixty keyboard - basically a rubber mat similar to the original Spectrum which sticks on top of the original ZX81 membrane. Wrong one Rich! This is the earlier plastic buttoned, Nee...

Re: ZX80 ZX81 Video options.

I have my ZX80 comp' modded with a ccb module and whilst it's ok on my colour CRT TV I get some bottom line distortion on my LCD TV which no amount of adjustment will get rid of.
