I bought one on ebay for $10 and paid $90 for shipping. It was not the B version, but the 74. This one had a regular underwood style printer ribbon which was nice. But like Ed's experience mine came coated in gooey roller drip. Much thicker than rubber cement. More like elmers glue just before its hard but thicker like melted vinyl. It was a beautiful machine and I think it would have been a great machine if it werent for the goo. Its great because it was small (but very heavy!) You could really roll a tank over it without a problem. I always liked the looks and size of that machine (loved the keyboard) but alas, it went out to the curb. I paid the garbage men another $20 in tip for taking it away. So for $120 I learned about gooey 74s'
73!

>with alpha and numeric charcters on metal fingers inserted into the
>belt. The belt rotated continuously in front of the paper and when the
>appropriate character appeared at the appropriate spot on the page, the
>type finger was whacked by a print hammer to drive the finger against
>the ribbon and onto the paper. There was a print hammer for each
>character position on the paper. Sheesh! If you can picture all that and
>think it was a Rube Goldberg machine, you're right.

>Well! The UGC-74B(V3) has a large drum (the axis of which is
>perpendicular to the edge of the paper) that rotates continuously BEHIND
>the paper. The drum contains a complete type set (letters, figures,
>punctuation, etc) for EACH character position on the paper. Like the
>Terminet, the machine's logic knows where the drum is at all times, and
>knows what character is supposed to print at each position, and tells
>the print hammer at the specified character position to whack the ribbon
>against the paper when the selected character on the drum comes around.
>Again, there is a print hammer for each character position on the paper.

>The real problem with the machine is that the paper feed rollers, which

>rollers were available, it is a major surgical operation to remove the
>drum to effect roller replacement. Not to mention cleaning the goo off
>of the drum and everything else it got on.

>The second big problem is that there are no replacement ribbons

>I speak from sad, sad, frustrating experience about this. I bought
