Floppies formatted on the Tandy 2000 have two incompatibilities which prevent standard PC's from being able to read them. First, the format is 80 track double density, a format that was never implemented on a standard PC using a 5.25" drive. This format is similar (tho not identical) to the one later implemented for 3.5" 720K disks. Second, the media descriptor and FAT ID bytes in the format were not those of the later-used 720K 3.5" format (80 track double density), but that of the 360K. A two-step problem requires a two-step solution. First, you have to have a way to make a standard PC recognize 80 track double density format in a 5.25" drive. The ZAPMID documentation refers to an early utility called INTRCPT, which I've not included because it's kinda cumbersome to use. I have instead included Alberto Pasquale's 800 II, which is very clean, runs from the command line, and simply adds capabilities to your existing drive letters. Just enter "800 " at the DOS prompt and you're ready to go. Second, you have to change the media descriptor and FAT ID bytes to something that your PC will recognize. ZAPMID does that. If your 1.2M drive is A:, just put your disk in A:, enter "ZAPMID A: ", and the disk is ready. With 800 loaded and ZAPMID having changed the appropriate bytes, you should be ready to get at those disks. The only real incompatibility problem you may have is if your PC uses some funky proprietary BIOS (I hate proprietary hardware!). If you have problems, let me know and I'll see if I can help.

All I can say is that they worked fine for me.
