Hi Folks,
I am old enough to remember typing in listings to my ZX-80 from the computer hobby mags at the time. Took a long time, then you had to debug to find the typing errors, then you had to debug to find the logic errors (and that was without the risk of physically destroying things that machine robotics/CNC can do) As soon as it became feasible magazines moved to electronic distribution (on cover disk, CD, etc ….)
Using printed listings in my opinion has all the issues above, plus this wastes valuable magazine space better used for words and photo’s when internet distribution is so much more efficient ( and cheaper!). I would think that anyone running CNC machinery would have at least a low bandwidth internet connection capable of transferring a few K of text files about.
BTW OCR depends on very high quality scans and a good portion of luck, not one for the MEW digital archive then …
Just my opinion.
Dave
