摘要: A single board multiple option card for expanding the versatility of a host computer includes an onboard microprocessor, digital signal processor and switched memory device. The is accessible by microprocessor under control microprocessor. further analog interface having plurality switches, positions which are controlled As result, options provided varying switches. Typically, such may include: "Invisible Keyboard"; "Voice Command Over Telephone Lines"; Store Forward Telephone"; Record Playback"; "Hands-free Telephone".
