-------------------------›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 ÒÅÔÕÒΛ6F0 ÒÅÔÕÒΛ›OSS DOS:›RUN 6F0 ÒÅÔÕÒΛ›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!›
