BTW, if we're at this subject, I'd suspect the '801 to be a descendant of some Japanese third-party manufacturer's printer (Seikosha if I'm right). I have a Seikosha printer wreck somewhere that looks exactly like the '801 and was (before hacked by some smart*ss) equipped with different data connectors whose shape remind me to the Atari serial port. Another interesting feature is that its head has just _one_ 'pin' and one magnetic coil. In fact this 'pin' is rather a slightly biased vertical 'bar'. You wonder how it was possible to put pixels onto the paper with this beast. There's a fluted shaft behind the paper that rotates with the head's horizontal movement. Pixel is put where the bar and the shaft 'meets' :-), everything is just a question of 'timing'. Wonder why then it wasn't possible to print 'bidirectionally' :-/. The major difference between the '801 and the '803 is this latter's real (8-pin) matrix-printer head :-). (I have a couple of '801s that I don't need -- If someone needs one I'd 'trade' them for some other stuff. I also have some refilled ribbon cartridges for them).
