HP 150 Financial Calculator Software Patent

[Martin Hepperle]

Recently, I revisited the US Patent 4,649,499 of 1987.

The PDF document describes the touchscreen software for the Cardfile and the HP-12C Financial calculator.
It mentions two appendices in Microfiche form.
These are not easily accessible to normal people like me.

Appendix B seems to contain program listings for the HP-12C simulator and would be very interesting.

Were these micro fiches typically filed together with the Patent documents and could they still exist? Maybe they have been converted to paper/scans? Or just deleted after so many years?

I could imagine, that someone working in the field of patents, might be able to retrieve copies of these appendices.
So I would like to know, whether someone has access to Patent publications at this level and especially to these micro-fiches.
