Use it when something fails and you want to send the log. Each run starts with a line like this one, where <code class=\"\" data-line=\"\">NN<\/code> is the build number:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\" data-line=\"\">---- SmartDisk II vX.YY.NN, run started ----\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How big it gets.<\/strong> The file grows up to 256 KB. Then the board renames it <strong><code class=\"\" data-line=\"\">SMARTDISK.OLD<\/code><\/strong> (the older <code class=\"\" data-line=\"\">SMARTDISK.OLD<\/code> is deleted) and starts a new <code class=\"\" data-line=\"\">SMARTDISK.LOG<\/code>. The two files hold 512 KB at most. The board keeps the log from power up, so the start of the boot is in the file when the setting was saved on.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When it writes.<\/strong> The board never writes in the way of the computer. It writes only when the setting is on, the card is free, and the emulation is quiet.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\"><table><thead><tr><th>Emulation<\/th><th>What &#8220;quiet&#8221; means<\/th><\/tr><\/thead><tbody><tr><td>Disk II<\/td><td>no track waits to be written and the Apple II has been off the drive for 200 ms.

If that memory fills before the board can write, the new text is dropped. The next write puts a line like this in the file:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\" data-line=\"\">---- 640 bytes of log lost: the ring was full ----\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">The number is an example. It tells you that the file has a gap of that many bytes at that place. A busy computer (a long copy, a boot from a 3.5 inch image) can make such gaps. A quiet board does not.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The memory line.<\/strong> Once a minute the log holds a line about the memory the board uses:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code class=\"\" data-line=\"\">mem: heap peak N of M bytes, stack peak N of 4096 bytes\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">With Log to SD on, this line is in the file. It shows how close the board came to the end of its memory.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3.5 trace log<\/strong> adds the dialogue between the 3.5 inch drive and its computer to this log.
