Panasonic HHC Snap Forth Reference manual wanted.

And or I am sponsoring a

construction of one from available information.

I will post pages as best estimated to be and will be open to suggestions for missing portions.

Anybody with a real HHC SNAPFORTH REFERENCE MANUAL please email as this would be a great help to us wishing to complete this project.

This will be extrapolated from a combination of other HHC manuals, AIM 65 Forth Manual, or testing and educated guessing.

It will be attempted to look as though it is an original manual by following a similar layout in the chapters and other charachteristics.

I know that there was one given to somebody in 1990 by a career programmer as yet not named for privacy.

Anybody have one of these in their closet?

Thank You,,

A fellow HHC fan

P.S. Also wanted detailed memory map for this computer.

I will post the data I know so far and would like any added information available to fill it out.

View map as is so far

HHC memory map

Here is some info from my memory of it's memory.

General memory block usage:

System and user built in RAM Hex 0000- 1FFF

Peripheral control ROM 2000- 3FFF

ROM banks up to 128 k per module address.

and LCD and system control chip and internal peripheral hardware

shared bank with any 16 k space 4000 - 7FFF

External add on RAM banks up to 128 k per module address. 8000- BFFF

System ROM including "Snap" Forth derived operating system C000 - FFFF

There could be an error here and it will be fixed once I look at my notes.

A more detailed map will be available soon and will be under constant construction.
