Back in 1989 I had OS-9 L2 running on a Coco3, with an LR-Tech HD controller and a SCSI drive. Recently recovered from floppies the backup of that setup. Here is the SDISK3 part of it, http://qdv.pw/coco/?p=426 Can't remember what is it, how is it used, is it complete? Any help would be appreciated. Kandur
