There's another problem with the NEXT manual, they left out the table of contents because they were not sure whether the manual would fit into the already ordered boxes
Yes, that’s another problem which unfortunately ruins it a bit. No glossary either, IIRC.
I stopped reading after a few pages and decided to buy a new set of glasses, first. But probably the Spectrum simply isn’t my machine, as I grew up with the C64 and familiarity is an important part of the retro experience, at least for me.
