This web tool lets you open existing TRS-80 Color Computer disk images, browse their contents, and copy files in and out. You can view files directly in the browser — including converting classic CoCo graphics formats to PNG (MAX, CM3, CLP, MGE, NIB, MAC, PCX, IMG, GIF, and Atari ST Tiny) and reading BASIC programs as text. Supports OS-9 VHD hard disk images, DECB/TRSDOS-style .DSK/.JVC floppy disk images, and other CoCo virtual disk formats.
