 The SX64 or SX -100 is a portable version of the CBM 64 and therefore identical to the technical data with a large extent to it. As you can see from the picture above Commodore inserted a 5.25″ drive with a spare bay for other devices such as an oscilloscope or another drive and included a 5″ Colour monitor. In the DX64 instead of the spare bay it had an additional 5″1/4 drive. The SX64 has a removable keyboard identical to that of the Commodore 64 and serves as a cover for both the monitor and the drive. Due to the small monitor, it is a bit uncomfortable to work with. Fortunately the SX64 has a socket to connect the machine to a normal monitor. On the right hand side of the device there is a small plastic flap, from which you can adjust the volume, brightness, colour and contrast. Additionally the SX64 has a carrying handle, which makes the computer portable. Since Commodore installed a 1541 compatible drive, they decided to remove the interface for the cassette tape. Although as a machine was as good as the Commodore 64 Commodore did not sell a lot of these machines, due to it’s expensive price. Commodore stopped the production of the SX-64 in 1986. The VIP 64 was the same as the SX64 except it was released for Europe users only.
