Editing Enterprise (computer) (section)

=== Interfaces ===

The Enterprise included an array of connectors far beyond what was common on home computers of the time. There is an [[RGB]] output, a [[RS-232]] / [[RS-423]] serial port, a [[Centronics]] printer port, two external joystick ports, two [[cassette tape interface]]s, a [[ROM cartridge]] slot, and an ordinary expansion port. To save expense, many of the connectors did not use sockets, but instead had simple [[edge connector]]s that used the exposed traces at the edge of the [[printed circuit board]].

The BASIC ROM can be replaced by a ROM that emulates a ZX Spectrum 48K, which allows the Enterprise to run the catalogue of thousands of Spectrum BASIC games and any other titles that don't access hardware directly; a hardware peripheral was available to provide more complete emulation for other Spectrum titles — catching Spectrum hardware accesses and issuing an interrupt so that emulation software can deal with them.

An external [[floppy drive]] became available later, and allowed access to [[CP/M]] programs, while at the same time being compatible with the [[MS-DOS]] disc format and [[FAT12]] file structure (sub-directories etc.).
