The following procedure is applicable to the following CoCo device types: CoCo-70X, CoCo-80X, and CoCo-90X. This update method requires software version 1.3.14 or later.

.bin files have a certain naming convention: CoCo80X_serialNumber_yyyyMMdd.bin

Regardless of the device type (C70X/80X/90X), the .bin file will always use the word “CoCo80X”. The extension will always be .bin. The file name should not be changed. Prior to updating, make sure that the serial number in the .bin file matches the CoCo device.

Place .bin file in SD card root folder

Place the file in the SD card root directory, and make sure that this is the only .bin file in the directory.

Log into CoCo and start update

Insert the SD card and boot up the CoCo (in either order is fine). Then from the home screen, navigate to the update button. Note that the Update function has been moved into the About menu in newer versions (see below):

On the following screen, press the Update button (F2). Then when it asks “Retain the old CSA file?”, press “Yes/Keep” (F6)*

* It is recommended to choose to keep the old csa files unless the user is trying to restore the default CSAs. Press “Reset/No” to restore all CSAs to the system defaults. This will also erase all custom CSAs, so it is advised that the user backs these up prior to resetting the CSAs.

The device will shut down once the update is finished. To verify that the correct software version was installed, press Setup > F2 (About). To check the software options, press Setup > F2 (About) > F1 (Software Options).
