According to the 22DISK database, Televideo 801 and 806 use a similar format (albeit with the sector numbering starting at 1), but we emulate neither. I'm not familiar with the Televideo series, e.g. if the TV802 uses the same disks and how to operate the machine. Another option would be MT CP/M for the TRS-80 Model 4, but I can't find disk images and the emulation only has SD images hooked up at the moment.
