Apple 410 ROM dumps

This directory contains the raw ROM dumps from the Apple 410 Color Plotter.

B9801Y[LMN].bin are images the three 8K 27C64 chips installed on the board. ROM.bin is the consolidated ROM image built by concatenating the three individual roms.

test_extractor.py is a script for extracting the self-test commands from the consolidated ROM file.

'font_extract.py' extracts the font as a set of SVG files. 'font_to_pickled_dict.py' generates two pickle files, one with the font and another with the point markers. Each pickle file contains a single dictionary mapping characters to the raw sequence of bytes that represents the glyph in the Apple 410's native format.

'ff_import.py' is a rough script for importing the SVGs into fontforge. The generated font will require a lot of manual cleanup.
