HP 86/87 Matrix Rom Manual
Obviously the HP 86/87 version of the matrix rom is essentially different from the HP 85 version, as it is composed of two ROM chips ( matrix 1 and 2; just one matrix ROM for the HP 85).
Therefore I assume that the HP 86/87 matrix ROM is more powerful and has more BASIC keywords than the HP 85 version.
On the internet only the HP 85 matrix ROM manual is available ( e.g. at, or ).
Does anyone know details about the additional functions in the HP 86/87 ROM, or even better, can anyone point me to a source for the manual?
