Keatah Posted August 18, 2018 Share Posted August 18, 2018 Thanks for creating what I don't have time to. I always thought this would have been cool to have as a kid, and be able to trade cards, or mail them to my buddies across town for pennies and no packaging. 1 Quote Link to comment Share on other sites More sharing options...
jhd Posted August 27, 2018 Share Posted August 27, 2018 This is very cool! Are you familiar with (or inspired by) Softstrip technology? I dimly recall seeing a few of those in magazines BITD. It is essentially a less dense/efficient implementation of the same concept. Quote Link to comment Share on other sites More sharing options...

I dimly recall seeing a few of those in magazines BITD. It is essentially a less dense/efficient implementation of the same concept. Not really, interesting stuff! Looks like the device could scan as well as print for $200 in 1985, advanced for the time. Sadly, nobody seems to have put a working demo on youtube yet, would like to see it in action. (You hear that, anybody who owns a working one?! Get on it!) In retrospect, their only chance of (even moderate) success was probably to make the format completely open (as QR codes did, it was patented only to protect it and open it to everyone from the get go) but in 1985 that was probably a pretty foreign concept for tech like this. I can't find any documentation on the format itself (wow, that's rare to find these days) but I suspect it had no error-correction and probably just basic CRC checks or something. But 50K data on a single magazine page is quite a lot for that day and age. Quote Link to comment Share on other sites More sharing options...
