Human Design Systems Inc and NCR Corp are among those X-terminal vendors now supporting PCMCIA standard peripheral cards on their workstations. The credit card-size adaptors provide a standard interface and small form factor for peripherals such as disk drivers, RAM expansion, flashPROM memory, modems and network adaptor cards. They are also used in personal computers and serial terminals. Human Designed will supply adaptor cards for $100, and is offering 2.6Mb and 5Mb Flash cards and 20Mb and 40Mb versions of Hewlett-Packard Co’s KittyHawk hard drives for $600 and $700 respectively. Human Designed also has a new X-terminal: the Intel Corp 80860CA-based FX14, which at $900 is said to be the cheapest X-terminal on the market. It is also fully expandable unlike some of its competitors, says Human Designed. The King of Prussia, Pennsylvania firm also added support for stereo sound to its X-terminal line with the HDperx multimedia option.
