Basically it is a modern computer in a retro looking keyboard case. Not worth the price though, it is a gimmick for all of the old school computer nerds who had one as a kid. I was too poor to pay the price back then, so I have no sentimental attachment. A TRS 80 though, now that might be something.
I couldn't afford one of those either but my cousin had one. I wrote my first programs on that little jewel.
