Hi folks,
    I've just found an AutoCAD R13 dongle in the bottom of a box I got at a
factory clearout sale. It's one of those Rainbow Sentinel devices and I
can't tell what device is in it 'cos its a globbed die(it could be a pic ?)

Anyone got and ideas as to how it works? Can I read/write it to and use it
to protect any of my own software?
I did a web trawl (a short one!) but came up blank. Has anyone got any info
on these things?
Best regards
John
