What DOS can read what Dos?
We have been asked several times about reading disks that are not formatted with the standard Radio Shack Model 3 or Model 4 disk operating systems.
WHAT CAN READ WHATReprinted from 17 Years of CN80 CD disk, Volume No3 Number 3, page 13Written by David GobenSo you have your favorite DOS running away and you get a disk from so-and-so and they tell you it is in such-and-such DOS format, which differs from your own. How do you know if your DOS can read that disk without going through some elaborate procedure? I am trying to ease the problem by providing some information on what can read what. In this presentation I am making use of some special keys. 1D means Single-Density, 2D means Double-Density, 1S means single-sided (1-sided disk), and 2S means double-sided (2-sided disk). Thus a references such as LDOS 1S 1D means LDOS single-sided single-density. If a special procedure is first required, it will follow the reference, such as "Use CONV/CMD". You will of course have to refer to the respective "Read from" DOS manual to see how to use such a program.This presentation is of course incomplete and you are encouraged to share your expertise where information is lacking by notifying CN-80 in writing (and in an ASCII-saved file on disk if you can), informing them of DOS compatibility or solutions to such problems.To start such a list off I will begin with TRSDOS 6.x, LS-DOS 6.x, and LDOS, which are 100% media compatible with each other. Needless to say they will read all formats of each other's disks. What I mean by this is that no matter if you format a disk single density or double density or single-sided or double sided under Model I or Model III LDOS, or Model 4 TRSDOS or LS-DOS, they can easily read any of the other's disk formats.
TRSDOS 6, LS-DOS 6 and LDOS can read:
TRSDOS 2.x (Model I) after using REPAIR
TRSDOS 1.x (Model III) by using CONV
DOSPLUS (Model I) 1S 1D after using REPAIR
DOSPLUS (Model III & 4)
1S 1D 2DNEWDOS80 1S 1D after using REPAIRULTRADOS 1S 1D after using REPAIR
TRSDOS 6 all formats
LS-DOS 6 all formats
LDOS (both Model I and III) all formats
