There appears to be some level of controversy over distributing 22DISK these days (a good write up is here), but I suspect it has to do with Sydex putting up a web page offering to read old disks for people (something I do on this site at no charge).

However, 22DISK requires “disk definitions” to read each disk. Larry Kraemer has prepared a set of “disk definitions” to enable 22DISK to read Model 4 Montezuma Micro CP/M to DOS, as follows:
