Appendix C— Creating User-Defined Bitmap Graphics and Fonts
228 IPL Programmer’s Reference Manual
Creating Six Bits Per Byte User-Defined Fonts
You can also create bitmaps in Advanced mode. In Advanced mode, each
data byte represents six bits in the bitmap. See the following example to
create a six bits per byte format like the previous one bit per byte (“$” and
“i”) bitmap font examples.
To download a six bits per byte format
1 Draw the character on graph paper.
2 Change the graph paper drawing into a pattern of ones and zeros.

3 Starting with the first column, divide each vertical column into groups
of six digits. (If the bottom group has less than six digits, add zeros to
this group until it also has six.) The six digits in each group are the six
bits that you download in a byte of data. The top digit of each group is
bit 0, and the bottom digit is bit 5.
