-------------------------¢DOCUMENTATION FOR SEQDOS:¢By TIM PATRICK - 08/28/87¢-------------------------¢¢SEQDOS (SEQential DOS) replaces the¢cassette handler with a disk handler¢that writes sequential files to drive¢one (D1:).¢¢It was originally written to allow¢fast development of cassette based¢software. You load and save to the¢"C:" device, except that the data is¢written to drive-1 instead of the¢cassette. This, obviously, will be¢much faster than a real cassette.¢¢Since no-one uses cassette any longer¢it would seem to be pretty useless¢now. But there is another practical¢use for a sequential DOS format!¢¢Using SEQDOS as an AUTORUN, you can¢load the handler from any DOS, and¢SEQDOS files are identical no matter¢what type of DOS is running!¢¢This will allow conversion of any DOS¢file format to any other DOS! It's a¢good way to get away from DOS 3.0 or¢DOS 4.0, and back to good ol' DOS 2!¢¢After the SEQDOS handler has been¢loaded, and DOS is active, put a¢blank(!) disk in drive-1 and run at¢$6F0 (see below).¢¢RUN commands:¢¢ATARI DOS:¢M פדקרפמ¢6F0 פדקרפמ¢¢OSS DOS:¢RUN 6F0 פדקרפמ¢¢This will format the disk in drive-1¢(NOTE: drive-1 must be configured as¢single-density!). Then you simply¢copy files to the "C:" device. The¢files are written sequentially to D1:¢one after another, so you may copy¢more than one.¢¢The first read after 1 or more writes¢'rewinds' the disk, and visa-versa.¢Hitting RESET will 'rewind' the disk¢also. (NOTE: my version of SEQDOS¢usually will recover from RESET, the¢original version didn't.)¢¢NOTE: It's a real good idea to write¢down the name of each file as it is¢copied to the SEQDOS disk. Otherwise¢unless you have a photographic memory¢you're going to forget what the file-¢names were before you can boot your¢target DOS and copy the files back!¢(SEQDOS does not use filenames or a¢directory... sequential, remember?)¢¢This should help you get back on the¢road to compatibility! For more info¢on SEQDOS see ANTIC, JULY 1984, pg.81¢for the original article.¢¢Keep on hackin'...¢¢Aloha from the Happy Hacker...TIM!¢əəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəəə
