RobPattonDotCom Posted March 28 Share Posted March 28 I have one working as D1 and D2, but I cant seem to sort out what the 8 dipswitches do, fully. It seems 5 changes the amdek to D2, but thats about all I can tell. Does anyone have a scan of the orig manual, or a list of what does what?!? Thanks!

+kheller2 Posted March 28 Share Posted March 28 PC version manual is here, I'm not sure if the dip switches would be any different for Atari https://archive.org/details/amdisk-iii-3-inch-disk-drive-users-manual/page/14/mode/2up Or here: https://www.atarimagazines.com/compute/issue46/040_1_REVIEWS_AMDC_3-Inch_Disk_Drives_For_Atari.php " Switches 1 through 4 are density selection switches that allow you to configure the drives for either single or double density on boot-up. The density of the boot drive is determined by the disk installed at boot-up. These switches have no effect if the controller is set for DOS 3.0. Switches 5 and 6 determine which drive will be the boot drive. The factory setting is for drive 1, but any drive up to and including 4 may be selected for this function. Switch 7 is used when more than three drives are connected to the controller, and is particularly useful when there is a 5¼-inch drive attached. When this switch is on, the external drive will be recognized as drive 1. When it is off, the 3-inch drives are 1 and 2, and the external drive is drive 3. Switch 8 sets drives that have been selected as dual density to 256 bytes per sector when off. When switch 8 is on, it sets all drives to be Atari 1050 compatible for use with DOS 3.0. When switch 1 is on, disks with 256 bytes per sector will not be recognized." 1 Quote Link to comment Share on other sites More sharing options...
RobPattonDotCom Posted March 29 Author Share Posted March 29 Awesome, thanks for that find. I wish the docs would expand on what "Switches 1 through 4 are density selection switches that allow you to configure the drives for either single or double density on boot-up" means. I know that all the switches up let me boot a disk I've made with mydos on it, and if I change any of the first 4, it no longer boots. But thats about it.

RobPattonDotCom Posted March 29 Author Share Posted March 29 I guess I just sorted it out 1-4 are SD or DD for the first 4 drives (I guess) But I'm still not exactly sure how 5-8 work. Guess I'll keep at it. Quote Link to comment Share on other sites More sharing options...
