Yeah, I still have one. It has a Z80 and some small number of K of RAM. It cost about $150. A serial port was another $100. It had a cassette interface for loading and saving programs, a 25X40 or so display (as another user remarked) and chiclet keys. I fooled around with it for a few days but found it to be too braindead to do anything serious with. One thing I hadn't seen before at that time, it had a couple of words, FAST and SLOW. SLOW, I believe, replaced the inner interpreter with one that performed some integrity checks, like checking stack boundaries, which was useful. -- -- uunet!ficc!karl "Have you debugged your wolf today?"
