Nice vid Greg.

Anyone spot the glider half way through?

Plus his is missing the printer cable this module generally comes with. I have this and the word processor module which has a genuine keyboard buffer which allows touch type speed with external keyboards alas only when the word processor is switched in, when switched out it's back to plod plod plod ...

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.

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.

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...

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.


Regards.

If you check City Of Xon I posted you will find they are one and the same game.

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...

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.
