PowerBook 190cs

The PowerBook 190 was Apple’s last model based on a Motorola 68040 CPU. The 190cs has an 8-bit dual-scan passive matrix color display. Apple eliminated the internal modem bay and the ethernet port found in the previous 500 series, forcing buyers to acquire these items separately.

PowerBook 190Because the PC Card uses a 16-bit bus, ethernet performance is roughly 25% slower than on the PowerBook 540.

Because the 190 and 5300 share the same case any many other enclosures, it is possible to upgrade your 190 with 5300 components by swapping in the video card (which adds support for an external monitor) and/or an active matrix screen. You can also install the infrared circuitry if you have a reason to. (Thanks to Jonathan Fletcher for sending in this tip!)

CPU Upgrades

  • Apple made a 100 MHz PowerPC 603e PowerBook Logic Board Upgrade Kit (M3881LL/A) for the PB 190, which effectively makes it a PowerBook 5300. This upgrade appears to be extremely rare.

Online Resources


  • From Apple Knoweldge Base Archive Article 19358: There is a known issue with the password security feature on the PowerBook 5300 and 190 series computers. This issue is resolved by installing the System 7.5 Update 2.0, which includes the Password Security 1.0.3 control panel.
  • The 100-series and 500-series PowerBooks do not provide SCSI termination power, depending on external SCSI devices to provide it. For more details, see SCSI Termination Power.
