• 4 MHz Z80 CPU
• 64 kilobytes main memory
• Fold-down 69 key detachable keyboard doubling as the computer case's lid
• 5-inch, 52 character × 24 line monochrome CRT display, mapped as a window on 128 × 32 character display memory
• IEEE-488 port configurable as a Parallel printer port
• RS-232 compatible 1200 or 300 baud Serial port for use with external modems or serial printers

Broken

The device needs a new floppydrive which we thought was available. But de Osborne has a special drive with power via the ribbon cable, not via the usual molex connector.
