2. Paper Tape Format

1" wide paper tape using 7- or 8-bit ASCII code, such· as a model 33 ASR teletype produces, or the 11/16" wide paper tape usi ng a 5-bit Baudot code, such as a Telex prod uces.

The format requirements are 'as fol- lows:

a.All word fields are to be punched in consecutive order, starting with word field 0 (all addresses low). There must be exactly 2048 word fields for the 2048 X 8 ROM organization.

b.Each word field must begin with the start character B and end with the stop character F. There must be ex- actly 8 data characters between the B and F.

NO OTHER CHARACTERS, SUCH AS RUBOUTS, ARE ALLOWED ANY- WHERE IN A WORD FIELD. If in pre- pari ng a tape an error is made, the en- tire word field, including the Band F, must be rubbed out. Within the word field, a P results in a high level output and an N results in a low level output.

c. Preceding the first word field and following the last word field, there must be a leader/trai ler length of at

least 25 characters. This should consist of rubout or null punches -(Jetter key for Telex tapes).

d.Between word fields, comments not containing B's or F's may be inserted. Carriage return and line feed characters should be inserted as a "comment")

just before each word field (or at least between every four word fields). When these carriage returns, etc., are inserted, the tape may be easily listed on the teletype for purposes of error check- ing. The customer may also find it helpful to insert the word number (as a comment) at least every four word fields.

e. Included in the tape before the leader should be the customer's com- plete Telex or TWX number and, if more than one pattern is being trans- mitted, the ROM pattern number.

f.MSB and LSB are the most and least significant bit of the device outputs. Refer to the data sheet for the pin numbers.

8080 specifications

The Intel 8085 and 8080 microprocessors were groundbreaking innovations in the world of computing, paving the way for future microprocessor development and personal computing.

The Intel 8080, introduced in 1974, was an 8-bit microprocessor that played a fundamental role in the early days of personal computing. With a 16-bit address bus, it had the capability to address 64 KB of memory. Running at clock speeds of 2 MHz, the 8080 was notable for its instruction set, which included 78 instructions and 246 opcodes. It supported a range of addressing modes including direct, indirect, and register addressing. The 8080 was compatible with a variety of peripherals and played a crucial role in the development of many early computers.

The microprocessor's architecture was based on a simple and efficient design, making it accessible for hobbyists and engineers alike. It included an 8-bit accumulator, which allowed for data manipulation and storage during processing. Additionally, the 8080 featured registers like the program counter and stack pointer, which facilitated program flow control and data management. Its ability to handle interrupts also made it suitable for multitasking applications.

The Intel 8085, introduced in 1976, was an enhancement of the 8080 microprocessor. It maintained a similar architecture but included several key improvements. Notably, the 8085 had a built-in clock oscillator, simplifying system design by eliminating the need for external clock circuitry. It also featured a 5-bit control signal for status line management, which allowed for more flexible interfacing with peripheral devices. The 8085 was capable of running at speeds of up to 3 MHz and had an extended instruction set with 74 instructions.

One of the standout features of the 8085 was its support for 5 extra instructions for stack manipulation and I/O operations, which optimized the programming process. Additionally, it supported serial communication, making it suitable for interfacing with external devices. Its 16-bit address bus retained the 64 KB memory addressing capability of its predecessor.

Both the 8080 and 8085 microprocessors laid the groundwork for more advanced microprocessors in the years that followed. They demonstrated the potential of integrated circuits in computing and influenced the design and architecture of subsequent Intel microprocessors. Their legacy endures in the way they revolutionized computing, making technology accessible to a broader audience, and their influence is still felt in the design and architecture of modern microprocessors today.
