CMDR-DOS：FAT32上的准将DOS
从流行的1541 5.25英寸驱动器到现代sd2iec SD卡接口，连接到Commodore 64串行总线的所有磁盘驱动器都使用Commodore DOS协议。CMDR-DOS是Commodore DOS协议的一种新的开放源代码实现，它使用具有FAT32文件系统的SD卡，并支持诸如分区，子目录和时间戳之类的高级功能，并且在65c02上运行！
指挥官X16
它的内置的DOS 指挥官X16，并运行在主CPU上，所以籽粒API（ ，talk，tksa，untlk，listn，secnd，unlsn，acptr）ciout直接调用进入DOS执行。LOAD在8 MHz系统上，这允许大约140 KB / sec的速度。

该实现是Commander X16 ROM的一部分，可在此处获取：
https://github.com/commanderx16/x16-rom/tree/master/dos
未来
该代码库非常通用，可以重用于其他类型的项目：
其他新型复古机
CMDR-DOS可以轻松移植到其他类似Commodore的65c02 +系统，例如MEGA65和C256 Foenix，从而在这些平台上为FAT32提供DOS接口。
类似于sd2iec的设备
从功能上讲，CMDR-DOS代码库也非常类似于sd2iec所做的事情-减去了Commodore Serial部分。可以将其移植到1581replica之类的设备上，该设备附有SD卡而不是磁盘驱动器，并且该设备将具有基于65c02的sdi2ec类设备。
