But the limit on directory entries to 112 and no sub directories ment you could have only 112 files on a 10 Meg hard drive. My first experience with CP/M (and Microsoft) was a Microsoft Z80 plug-in for the Apple II. My early PCs also had Z80 plug-ins so that I could use my Microsoft CP/M basic complier for 8080 software development. Digital Research DOS Plus allowed one to read both DOS and CP/M disks, A great boon at that time. Mike Vince
