VIC Wafer Storage
low-cost micro-wafer storage device for the VIC-20 will be available
later this year from Unitronics, through a licensing agreement with
Vadem, the unit's builder.
The V-20 Expander is described as an inexpensive
alternative to floppy disk storage for low-end computers. It reads or
writes data to small tape cassettes at a speed approaching that of
The device, which measures 5x6x7 inches, plugs into
the VIC's cartridge expansion slot. It includes a 10K RAM memory
expansion board, a 64K data wafer and high-speed microwafer drive, a
filing system, and VWOS - the Vadem Wafer Operating System.
Because VWOS is able to access the computer's memory
bus directly, rather than through a serial port, the V-20 is able to
improve on the data transfer rates of existing micro-wafer devices.
The expander is expected to sell for about $100.
