With it, you do not need the keys of the board to load an image.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Apple II boots the SmartDisk II as if it were a normal 5.25 inch disk. The program that loads shows the images of the SD card in 40 column text. You choose one with the keyboard, and the Apple II restarts on it.<\/p>\n\n\n\n<h2 id=\"1-what-it-is-and-on-which-machines\" class=\"wp-block-heading\">1. What it is, and on which machines<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The Smartloader is a small program that the board holds in its own memory and serves as a boot disk. This firmware carries version <strong>0.53<\/strong>. The version is at the bottom right of the Apple II screen (<code class=\"\" data-line=\"\">V0.53<\/code>).<\/li>\n\n\n\n<li>The board serves it through the Disk II emulation (<a href=\"https:\/\/www.r3tr0.net\/index.php\/smartdisk-ii-documentation\/smtdoc_disk-ii\/\">Disk II emulation<\/a>). Any Apple II that can boot a Disk II can run it, with at least 48 KB of RAM. The connection is the one of the Disk II (<a href=\"https:\/\/www.r3tr0.net\/index.php\/smartdisk-ii-documentation\/smtdoc_hardware-installation\/\">hardware page<\/a>).<\/li>\n\n\n\n<li>It runs on the IIgs too (through the DB-19 port).
