Thanks Ward and Tony, I guess the original problem was the nut between the keyboard and the chair. Who'd thought there was a Y-1987 problem. I downloaded LS-DOS and TRSCROSS and got them transferred to the TL/2. Using TRSCROSS, I am able to format disks that are readable by the Model IV on that system. Now, I need a little help getting LS-DOS to boot on the IV. When I tried to copy LS-DOS to a disk (using TRSCROSS), it told me the file name was not valid. Assuming the file needs to be renamed, what should the file name be? Is there anything special I need to do to make this a bootable image? If someone could provide step-by-step instructions, I'd really appreciate it...

Normally it prompts for the date first (actually, both the date and time prompts can be enabled/disabled by the appropriate command...). Are you giving it a valid date or time? Note that a lot of TRS-DOS 6/ LS-DOS 6 versions will only take dates between 1980 and 1987. Try a date in that range. The best fix for that is to upgrade to LS-DOS 6.3.1. You can get a disk image (and the source) from Tim Mann's web site. To get the disk image to a real disk you can use either xtrs (a trs-80 emulator which uses X) under linux, or a little program I've written, also for a linux box, that simply writes disk images to real disks. Let me know if you (or anyone else) wants the latter. If you really can't get it locally, I can write you an LS-DOS 6.3.1 disk and post it to you. Of course the post might well mangle it :-( -tony
