Kubla Khan and the 75d
Message #1 Posted by Andy on 7 Feb 2003, 9:52 a.m.

Last night I was attempting to determine the contents of a 32k CMT eprom for my 75 by utilizing the HELP LEX file. The HELP LEX file lists all of the keywords on the 75 or in a given LEX file (see DataFile: V7N5P28) and can be quite handy when trying to decipher undocumented LEX files.

Anyway, I was reviewing the keywords when I came across one called "KUBLA KHAN". When I typed "KUBLA KHAN" into my 75d (at the BASIC prompt) and pressed enter, it displayed (rapidly) the poem by Samuel Taylor Coleridge. By setting the display to the 82164a (display is ":I1") I was able to capture the output to a file as well.

Certainly others have already figured this out, however, I have never seen it documented anywhere so it was kind of like discovering it myself!

If you've seen this easter egg documented in any of the journals, please post the reference.

You can find details about it in this excellent book:

"A Guide to HP Handheld Calculators and Computers" by W.A.C. Mier-Jedrzejowicz, Ph.D., 3rd edition, ISBN: 1-888840-30-7.

in the section dedicated to the HP-75D
