The DECstation 5000/240 can be seen as an improved version of the DECstation 5000/200. It has an additional high-resolution timer, better serial interface chips, and the CPU and Cache are sitting on a separate module plugged into the mainboard. DEC offered an upgrade to a 60 MHz R4400 CPU, which makes this machine to a respectable workhorse even for today's standards. If you bought such a machine with the upgrade already installed, the machine was labelled as a 5000/260.

Common with the 5000/200 is the almost obscene amount of memory modules you can plug into it, the three TurboChannel slots and the case that has no space for internal drives...
