The HP 100LX and HP 200LX palmtop computers used a custom icon format, with filename extension .ICN.

Format
We did not find much documentation about this format, but the examples we've seen use a simple uncompressed bi-level format, with an 8-byte header. The image dimensions are stored in the header, but they are probably always 44×32.
Identification
A file begins with bytes 01 00 01 00.
Assuming dimensions of 44×32 pixels, the next four bytes are 2C 00 20 00, and the file is exactly 200 bytes in size.
