Sinclair came out with this device a year earlier, but it was in 1979 that electronics retailer JS&A offered it for almost $150 less than Sinclair was selling it.
The Sinclair's rechargeable batteries were built into the unit. It came with an American AC adapter and charger, earphones, carrying case, rechargeable batteries and a built-in antenna for both VHF and UHF. It also came with a cigarette lighter power converter, in the days when cars and boats had cigarette lighters!
