The fonts were chosen to reduce storage space which is a bit rough on the eye. As Grant mentioned, the 'R' is ugly. The 'K' is about the same, maybe a little worse. This and the lack of lower case letters make reading a novel on the rs-big-print painful. But, if reading a thermal monitor in a casting process or the digital readouts on a machine tool or the output of a weather monitor from

10, 20 or 30 feet, the rs-big-print starts to shine. The 6 line/12 characters look big, even on an old 13 in. monitor and at 20 & 30 feet they are comfortable to read. All in a 2.5 x 1.75 x .8 in. box. It still pays to avoid the r's & k's though.

Some of the displays showing rs-big-print messages were changed to full size to make the purpose more visable. If you get a chance to look, it's at

- Due in large part to messages here and rec.crafts.metalworking about

-searches for various type of crt controllers I've built one & placed it on

-the market. It generates large letters in 8 line/20 characters per line

-and 6 line/12 characters per line formats.

- A 9 pin d-sub connector for rs-232 input and a 15 pin hd dsub

-connector for output to a vga monitor are enclosed by a small plastic

-housing. At one side is a connector for a "wall mount" style transformer

-which is included.
