External Hardware IO Address Map
Tandy designated IO addresses from $FF60 to $FF7F for add-on hardware, but several parties chose to build in the $FF40-$FF5F range as well. Here are known IO addresses for add-on hardware. Built-in devices (such as the SAM, GIME, PIAs, etc) are not included.
- FF40-FF4B Floppy Disk Controllers. See Hardware#Floppy_Disk_Controllers for list.
- FF40-FF4B MEGA mini MPI Serial UART A (gated via $FF7F)
- FF40-FF45 MEGA mini MPI Extended MPI Features (gated via $FF7F)
- FF4C-FF4F Some third party Floppy Disk Controlers: Sardis, JFD, Disto Super Disk Controller, and Disto Super Disk Controller II
- FF50-FF5F Glenside IDE Controller (first jumper option)
- FF50-FF54 MEGA mini MPI YMF-262 sound generator (gated via $FF7F)
- FF50-FF57 Disto Super Disk Controller
- FF50-FF59 Cloud-9 SuperIDE Interface Default Address Range, modified with jumpers
- FF50-FF5F Disto Super Disk Controller II
- FF50-FF5B MEGA mini MPI Serial UART B (gated via $FF7F)
- FF5A-FF5F CoCo PSG
- FF59 Cloud-9 miniFLASH default address, modified with jumpers
- FF60-FF62 X-Pad Model GT-116
- FF68-FF6B Deluxe RS232 Pak
- FF68-FF6B CoCoIO (first jumper option)
- FF6C-FF6F Direct Connect Modem Pak
- FF6E-FF6F MIDI Maestro
- FF70-FF7F Glenside IDE Controller (second jumper option)
- FF74-FF75 Cloud-9 TC^3 SCSI Interface default settings, modified with jumpers
- FF74-FF77 Disto Super Disk Controller II
- FF7A-FF7B Orchestra-90 CC (26-3143)
- FF78-FF7B CocoIO (second jumper option)
- FF78-FF79 & FF7C Cloud-9 SuperIDE Interface Real Time Clock
- FF7D-FF7E Speech/Sound Cartridge (26-3144A)
