Upgrade Your Multi-Pak To Work With The CoCo 3

These upgrades allow the Radio Shack's 26-3x24 Multi-Pak to work properly with the CoCo 3. Without this modification, the Multi-Pak and CoCo 3's memory map overlap and can cause unpredictable results, possibly even data corruption under certain conditions.

If you're running an non-upgraded 26-3x24 Multi-Pak with a CoCo 3, don't take a chance. Installation of the upgrade is easy – The 26-3024 has no soldering required.

The 26-3124 requires a trace to be cut and seven wires to be soldered to the MPI’s circuit board. A Cloud-9 installation service is available below if you do not want to attempt the installation or have the soldering tools.

Does My Multi-Pak Need This Upgrade?

Here's a simple test that will determine if your Mulit-Pak has already been upgraded to work with a CoCo 3. From BASIC's OK prompt, type PRINT PEEK(&HFF90) and press ENTER. If 126 is returned then the Multi-Pak has been upgraded. If it returns 255 then it has NOT been upgraded.

Standard Features

  • Updates your Multi-Pak 26-3024 or 26-3124 properly for CoCo 3 use
  • Quick and easy installation
