Also, since the “bus” places additional load on the unbuffered expansion port IO lines, cartridges that are susceptible to signal degradation may not work with X-Pander 3, even when installed alone.Some helpful hints:Always insert or remove X-Pander 3 with the system port offClean cartridge contacts before installationSwitches are “on” when depressed. Thus, it is impossible to detail the nearly infinite combinations and whether each works or not. Our thanks to Carsten Jensen for creating the X-Pander3 User’s Manual.Expansion port cartridges were not normally designed to coexist with other cartridges. Jumpers are provided, but the jumper pins can be removed and replaced with a subminiature DPDT (double pole, doub e throw) switch.SupportThe unit works exactly like the Creative Micro Designs EX3 (EX2+1) units, so instructions for those units will work equally well with the X-Pander3.

This can be used to move a peripheral cartridge (like a serial card or ethernet card) normally residing at IO2 to the alternative IO1 position so that it can coexist with the RAM Expansion Unit, which must reside in IO2. The X-Pander 3 offers the following features:3 individually-selectable expansion portspower indicators for each portAbility to swap IO select lines on 2nd and 3rd portseasily accessed piano-style configuration switchestop-loading or back-loading 3rd port.3rd port can accommodate 2 cartridges at the same time*reset switch* Both top and back-loading options for port 3 share a single set of configuration switches, requiring 2 cartridges that can coexist without configuration.RequirementsCommodore C64, C64C, C128, C128D, or SX64Technical DetailsX-Pander 3 creates a “passive” cartridge port “bus”, with switches on the following lines:Power (2 switches)IO1 ($de00-$deff)IO2 ($df00-$dfff)ROML ($8000)ROMH ($a000)EXROMGAMEAdditionally, ports 2 and 3 contain jumpers allowing one to “swap” IO1 and IO2. Utilize multiple cartridges at once, or easily switch cartridges without removal. Github link: heir-apparent to the CMD EX-3 and EX2+1, the X-Pander 3 opens up a wealth of expansion options for your Commodore 64, SX64, C128, or C128D.
