Description

The JVC HC-7E is the Victor HC-7 localized for the European market and features a "international" keyboard with a £ key.

The superimposing features and the firmware ROM have been removed. However, the Victor HC-A602S module is still built-in, but the Monitor/VTR Record connector has been replaced by a Monitor connector and the Balance slider has been removed.

This computer is available in dark silver. It seems to be the same as the JVC HC-7GB, except for the power supply (220V instead of 240V).
