This article provided an overview of the RDISK, remote disk protocol for the MIC80. The RDISK protocol allows the MIC80 to mount a one megabyte file located on a remote host as a CPM2.2 disk. RDISK uses the UDP network protocol to transfer data between a client and host. The server side of the RDISK protocol is currently implemented in the Z80Emu program. The Z80Emu program can also be used to, create disk image files and manage the files contained in a disk image. The Z80Emu program can manage the files in a disk image either by mounting the disk under CPM or by using the built in file manager functionality.
