PowerBook 190cs

The PB 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, forcing buyers to acquire the separately. Because the PC Card uses a 16-bit bus, ethernet performance is roughly 25% slower than on the PB 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!)
