Computer Transceiver Systems Execuport XL

The Execuport was a hybrid CP/M, MS-DOS system. You could start with the base Z80 model running CP/M and later upgrade to an 8086 or 80186 processor for MS-DOS compatibility. Many if not most of the CP/M system manufacturers took a similar approach at the time as a hedge against the growing dominance of MS-DOS.

The base Z80 model was called the Execuport XL, and the 8086/80186 model was the Execuport XL+. The XL+ could also run CP/M as well as several multi-user operating systems. Both models shared the same physical configuration with a built-in monitor in a reddish brown case. One unusual feature was the 132-character-wide screen. Most systems of the era offered 80-column screens.

Computer Transceiver Systems had earlier produced Execuport-branded portable terminals. The company launched in the late 1960s as a manufacturer of computer peripherals.
