Amiga
The Amiga family of personal computers were introduced by Commodore in 1985, and unlike its competitors had custom hardware for sound and graphics. The Amiga line was officially discontinued when Commodore went bankrupt in 1994, but the Amiga community continued releasing software for it long afterwards.
NetHack 3.0.0, released in 1989, was the first version of NetHack with official support for the Amiga; both NetHack 2.3e and 3.0 were also ported to the Amiga by Olaf Seibert, according to the game history. The Amiga port was dropped for 3.3.0,[1] but "resurrected" in 3.3.1. The Amiga continued to be supported until NetHack 3.4.3, which remained the newest version of NetHack from 2003 to 2015.
It is unknown if NetHack 3.6.4 can build or run on the Amiga, according to that version's README.
NetHack 5.0.0 has an official binary for Amiga.
Font
NetHack 5.0.0 has an entry in the symbols file for the Amiga. This entry addresses a font that is packaged as sys/amiga/amifont.uu and sys/amiga/amifont8.uu. These files are uuencoded. amifont8.uu decodes to a file called hack/8; this file contains the actual bitmap data.
This site describes the font format. The structure described in the site begins at offset 0x20 in the file.
The font is laid out below. It is unchanged since NetHack 3.1.3. The image below is expanded threefold for readability at modern screen resolutions.
Positions 20 through 7E are ASCII, as one might expect. Positions 80 through 8F, 96 through A0 and EE contain substitution glyphs. Positions A1 through BF, DB through E0 and FB through FF repeat glyphs seen in the lower half. Position 95 repeats position C6.
The positions used in the bundled symbols file are 91 through 94, C0 through C6, D4 through D9, E5 through ED and EF through FA.
Positions 7F, C7 through D3, DA and E1 through E4 contain usable and distinct symbols. D3 in particular looks like a throne.
