"Intel P8256AH old chipset to 8080 8-bit systems"

[TymoZXDev]

I am looking for good documentation or any possible to Intel P-8256-AH.

I already have few docs in PDF files.

I have lost in strange way doc in PDF as Intel Application Note "AP-150" series. I don't remember good number of application note, but it was series AP-150.

Number is between 150 and 160 for sure. Name is something like "~Programming of P-8256-AH~".

I have another one: AP-153 - "Designing with the 8256". It is good.

Another one is for complete information about details of programming 8256 AH.

It is not so necessary, but I will very happy to have this.

If somebody knows where can I find it? 

Probably could be in collection of Application Notes or in appropriate "Data-book" from past years.

It is very hard to find it because this documentation could have encoded number of doc, different of the real title and number of note.

P.S.

Nearest possible numbers are:

AP-156

AP-157

or encoded number of doc in the web as : 2010901 etc.

I think you've got the wrong forum.  This doesn't have anything to do with FPGAs.

If I remember this documentation I found thanks to Google search results, it was encoded by number at first position from Bitsavers.org

This service is very large and it is difficult to find it out even if I know it was from Bitsavers.org. It was for sure Intel Aplication Note AP-170 and greater but up to 160. "Programming 8256 AH". I will try to find it out anyway and search this service by myself. Thank You.
