The Apple Computer. A truly complete microcomputer system on a single PC board. Based on the MOS Technology 6502 micro- processor, the Apple also has a built-in video terminal and sockets for 8K bytes of onboard RAM memory. With the addition of a keyboard and video monitor, you'll have an extremely powerful computer system that can be used for anything from developing programs to playing games or running BASIC.
Combining the computer, video terminal and dynamic memory on a single board has resulted in a large reduction in chip count, which means more reliability and lowered cost. Since the Apple comes fully assembled, tested & burned-in and has a complete power supply on-board, initial set-up is essentially "hassle-free" and you can be running within minutes. At $666.66 (including 4K bytes RAM!) it opens many new possibilities for users and systems manufacturers.
You Don't Need an Expensive Teletype.

avoid all the expense, noise and mantenance associated with a teletype. And the Apple video terminal is six times faster than a teletype, which means more throughput and less waiting. The Apple connects directly to a video monitor (or home TV with an in- expensive RF modulator) and dis- plays 960 easy to read characters in 24 rows of 40 characters per line with automatic scrolling. The video display section contains its own 1K bytes of memory, so all the RAM memory is available for user programs. And the Keyboard Interface lets you use almost any ASCII-encoded keyboard.
The Apple Computer makes it possible for many people with limited budgets to step up to a video terminal as an I/O device for their computer.
No More Switches,
No More Lights
Compared to switches and LED's, a video terminal can dis- play vast amounts of information simultaneously. The Apple video terminal can display the contents of 192 memory locations at once on the screen. And the fimrware in PROMS enables you to enter,

display and debug programs (all in hex) from the keyboard, ren- dering a front panel unnecessary. The firmware also allows your programs to print characters on the display, and since you'll be looking at letters and numbers instead of just LED's, the door is open to all kinds of alphanumeric software (i.e., Games and BASIC).
8K Bytes RAM in 16 Chips! The Apple Computer uses the new 16-pin 4K dynamic memory chips. They are faster and take 1/4 the space and power of even the low power 2102's (the memory chip that everyone else uses). That means 8K bytes in sixteen chips. It also means no more 28 amp power supplies. The system is fully expandable to 65K via an edge connector which carries both the address and data busses, power supplies and all timing signals. All dy- namic memory refreshing for both on and off-board memory is done automatically. Also, the Apple Computer can be upgraded to use the 16K chips when they become available. That's 32K bytes on-board RAM in 16 IC's --the equivalent of 256 2102's!
