HP 86/87 Matrix Rom Manual

[Michael Fehlhammer]

Thanks Ray,
but unfortunately this manual also covers the HP 85 version of the matrix ROM ( only ).
Perhaps there is kind of an addendum for the additional functions in the HP 86/87 matrix 2 ROM, or I would need the HP 86/87 manual version - or my assumption was wrong that there are additional functions. But what else should be included in the second ROM ?
