OWNER’S MANUAL — Please read before using this equipment.

 

 

Two Power Options — let you power the keyboard from internal batteries (not supplied) or standard AC power (with an optional adapter) so you can make music almost anywhere (see “Connecting Power” on Page 2).

12-Note Polyphonic Sound — lets you play and hear up to 12 notes at the same time, so you can play or create almost any type of music.

100Auto-Rhythms — provide a steady beat for many styles of music, from rhumba to rock (see “Percussion Sounds” on Page 6).

100 Tones — let you set your keyboard to sound like anything from a harpsichord to a honky- tonk piano (see “Using the Preset Tones” on Page 5).

100 Prerecorded Tunes — let you hear a sample of what you and your keyboard can do. You can play the tunes either one at a time or consecutively, and you can turn off the melody or accompaniment portion so you can play along with the tunes (see “Playing the Prerecorded Tunes” on Page 5).

61 Full-Sized Lighting Keys — light as the keyboard plays a tune, to help you see which keys to press and develop your music skill (see “Using Lesson Mode” on Page 8).

This Owner’s Manual explains how to use this electronic keyboard. It does not teach music.

LK-1161 specifications

The Radio Shack LK-1161 is a notable entry in the realm of personal computing, particularly recognized for its balance of affordability and functionality. Released in the early 1980s, the LK-1161 was a powerful home computer that captured the attention of tech enthusiasts and casual users alike.

One of the standout features of the LK-1161 was its keyboard design, which catered to users looking for an efficient and pleasant typing experience. The integrated keyboard not only streamlined the design of the computer but also provided tactile feedback that many found appealing. This made the LK-1161 a popular option for those who required a reliable interface for programming and word processing.

The LK-1161 was powered by a robust Zilog Z80 microprocessor, a popular choice in many 8-bit computers of that era. This processor enabled the computer to handle various software applications efficiently, making it suitable for both home and educational use. With a clock speed of 4 MHz, users could enjoy a responsive system capable of multitasking between simple applications.

In terms of memory, the LK-1161 was equipped with 64KB of RAM, expandable to higher capacities with additional modules. This flexibility allowed users to adapt the computer to their needs, install more advanced software, or handle larger projects. The built-in BASIC programming language also provided a foundation for users to explore coding, making the LK-1161 a popular choice among budding programmers.

The graphics capabilities of the LK-1161 were modest compared to modern standards but were acceptable for its time. With support for several display modes, users could enjoy text and simple graphics, making the computer suitable for early gaming experiences and educational software.

Storage options included a built-in cassette interface for loading and saving programs, and users could also connect external floppy disk drives to enhance storage capabilities. This adaptability made it easy for users to manage data and software without relying solely on cassette tapes.

Connectivity was another strong point, with RS-232 serial ports allowing users to connect printers and modems. This facilitated data transfer and made it easier to print documents or connect to bulletin board systems.

Overall, the Radio Shack LK-1161 emerged as a versatile computing solution in its era, offering a way for individuals to engage with technology. With its blend of operational efficiency, user-friendly design, and expandability, it remains a memorable piece of computing history, symbolizing the early days of personal computing and its journey towards the modern era.
