CP/M 2.2AT Combo Altair/Tarbell BIOS for Altair 8800

Demonstration of a CP/M 2.2 BIOS for the Altair computer that supports both the Altair and Tarbell floppy controllers at the same time. Drives A & B are Altair drives, while drives C & D come off the Tarbell controller.

Is it possible to have 5 drives connected at the same time? I believe that in a previous video you noted that the drives were numbered 0, 1, 2, and 3, but could there also be a fifth drive?

So does the program ASM support reading/writing to many disks or have you had to modify it to do that?
