Oracle", and the C series brochure notes a "cable TV interface for teletext" as optional. The microcassette facilities featured in the C series brochure were reportedly prototyped as a peripheral, and the telephone handset featured in the brochure was supported by an optional bracket. General expansion capabilities were provided by an "Electron-style expansion connector" as also featured in the Master Compact. The machine offered no built-in storage mechanism (such as a disk drive) nor a connector for an external storage mechanism, although the C series brochure mentions a 3.5-inch disk drive as an option. A separate file and print server "in the same style as the Communicator itself" offering floppy and hard drive support plus a Centronics printer interface, based on the 6512 CPU and having 64 KB RAM plus 64 KB ROM, was intended to be the means by which Communicator machines, fitted with a standard Econet module, would access files and print documents. The Acorn Filestore product had essentially this specification and capabilities, and documentation was made available describing its use with the Communicator. Distinct versions of the FileStore E01 base unit and E20 hard disc unit were made for use with the Communicator, these having a different colour but, in the case of the E01 unit, also providing different software. The E01S unit was also usable by the Communicator and could be expanded by the E40S and E60S hard disc units. The Communicator provided an office software suite, including View (word processor), ViewSheet (spreadsheet), Videotex and VT100 terminal emulation, plus Econet local area networking, a telephone line input port for connection to the public switched telephone network (PSTN), an RS423 serial port for connection to serial printers or other computers, and a Centronics parallel port to connect a printer. The system software that bound the packages together was a mixture of BBC Basic and assembly language. The software development team was led by Paul Bond, who led development of the original Acorn MOS, a keen pilot who would occasionally fly team members in his Cessna when things were quiet. First versions of the Communicator were monochrome-only; later (but before first customer delivery), a daughterboard provided full colour. A briefcase version of the Communicator was apparently offered as the Spectar II by Advanced Medical Communications, supposedly for use by pharmaceutical company representatives, offering a bar code reader and "credit-card size memory packs", with one version having "a flat
