HP-29C Neutral Operations

[teenix]

Apologies for those who downloaded the modified source code for the 29C if had a flaw.

Attached is a zip file containing modified files for 19C and 29C to match the Neutral operations mentioned in the owner's manual.

Unfortunately, because of the structure of the original microcode, there may still exist problems when the code operates under certain circumstances. This would require analysis of every pathway in the code which would be a mammoth task, however I haven't noticed an issue.

cheers

Tony
