The new 4.7 version resolves a problem with switching between localtalk and serial devices while using a Performa 6400. In addition, more devices have been added to the "Device" list.
Installing the Update
There are two extensions that need to be manually dragged into your extensions folder*. Use one of the following combinations:
1. "Port Juggler" & "PJ Classic" for Port Jugglers received before June of '96.
2. "Port Juggler" & "PJ 4x" for the Port Juggler 4x.
*Note: Before you install the new Port Juggler 4.7 software you want to remove and trash any earlier versions from your system folder. If you have earlier Port Juggler software, it should be in either your Extensions folder or the Extensions (Disabled) folder. There may also be a file named "Port Juggler Prefs" in your Preferences folder, which should also be trashed.
**If you have a Power Port Juggler you will need to determine which version of the PJ Power software to use. The examples below should help you decide.
 
If you have a Power Port Juggler with 5 silver serial connectors then you will need to install the "Port Juggler" & "PJ Power5" extensions.
 
If you have a Power Port Juggler with 3 silver serial connectors then you will need to install the "Port Juggler" & "PJ Power3" extensions.
