Password protection? There wasn't any as part of CP/M. <The CP/M 3+ manual says the syntax is drive:12345678.123;password. <Maybe it's a weird DR thing. They tended to add weird stuff... You didn't say CPM3! If you say CPM it is assumed the more common v2.x version. V2.x did not have passwords, V3.0 did. Obviously if this apple cpm card has V3 disks it it was a very late one or someone went to some trouble to port v3 to it. FYI: v3 was not widely popular. Allison
