    1. Congratulations! Thank you for purchasing the miniFLASH, another one of the fine products offered by Cloud-9. This product was designed to be used with the Radio Shack/TRS-80 Color Computers 1, 2, and the Tandy Color Computer 3. The miniFLASH allows you to use FLASH technology to store ROM Pak images or your favorite DOS.

    We know you’re excited about using your new miniFLASH! However, before you plug it into your CoCo, please read the following pages carefully for important configuration information. Examining the Interface There are a number of DIP switches on the miniFLASH that must be set properly to reflect your particular system DIP Switches The DIP switch block has three switches, and can be accessed even with the cover in place.

    You will learn shortly how to set these jumpers for your specific system setup. Configuring the Interface In order to insure that your miniFLASH matches your Color Computer system, it is important to set the state of the jumpers to reflect the proper base address as well as FBSR reset behavior.
