Olivetti P 6060
General purpose, desktop system, programmable In BASIC
The basic unit consists of:
— central memory (RAM) — read-only memory (ROM)
— arithmetic-logic unit — full alphanumeric keyboard
— console
— alphanumeric display
— floppy disk read/write unit (single drive).
The basic unit options are:
- central memory extensions
- integrated alphanumeric printer
- second drive for floppy disk read/write unit
- one or two Olivetti Standard (IPSO) interfaces, for connection to compatible peripheral units
- DCC 6609 interface, for connection to the moving head disk cartridge unit
- asynchronous line control unit for time-sharing applications and for connection to compatible
EIA RS 232 C (CCITT V 24) peripheral units.
Basic Unit
Central Memory
(RAM - Random Access Memory) MOS integrated circuit design. Capacity of 40K 8 bit bytes, of which:
- 32 kbytes are reserved for operating system resident on floppy disk
- 8 kbytes are available to the user for program and data storage. Access time: 700 nsec.
Read Only Memory (ROM)
ROM loader - consisting of bi-polar LS I circuits - for calling the operating system into the reserved area in central memory (32 K). Loading occurs automatically when the system is activated.
Access time: 350 nsec. Arithmetic-Logic Unit
Receives and executes program instructions from central memory. Input/Output Channels
16 channels for exchange of information between the central unit and input/output units (both integrated and peripheral).
Total overlapping of input/output and processing operations.
Mode of operation:
- multiplexor, for simultaneous management of input/output interfaces
- selector, for high-speed
management of one input/output interface
- Direct Memory Access (DMA). Alphanumeric Keyboard
Electronic keyboard, with 80-character buffer:
- alphanumeric BASIC section, for entering statements, commands, and alphanumeric strings (26 full BASIC words on single keys)
- editing section
- algebraic section, for entering numeric data and algebraic operators
- section for user-definable functions under either program or manual control
- two end-of-line (EOL) keys
- result keys, for recalling four stack registers in calculator mode
- command section, with full commands on single keys. Console
Consists of:
- illuminating switches for selection of operating modes
-- indicator lights to show system status
- decimal wheel to select output precision in calculator mode.
Alphanumeric Display
Plasma display can represent complete set of ISO characters (upper and lower case, special characters, etc.). Capacity: 32 characters (5 x 7 matrix). Pointer to indicate current operating position.
80-character buffer.
Pointer can be shifted, and line «moved» left or right when consisting of more than 32 characters (up to maximum of 80 characters).
Display shows:
- keyboard entries
- programmed data and messages
- system messages
- complete program lines
- lines of text
- results in calculator mode
- error messages.
Floppy Disk Read/Write Unit
For exchange of operating system, program, data and text files between floppy disk and central memory. Exchanges are carried out in blocks of 128 characters.
Average access time: 333 msec (including latency and settling time). Nominal transfer speed: 250 kbits/sec.
Central Memory Extensions
Central memory can be expanded to 48, 56, 64, 72 or 80 kbytes (corresponding to 16, 24, 32, 40 or 48 kbytes of user memory).
Integrated Alphanumeric Printer
Thermal serial printer, handling complete set of ISO characters (upper and lower case, special characters, etc.).
Printing line: 80 characters (5 x 7 matrix).
Printing speed: 80 char/sec.
Two buffers, 80 characters each.
Prints program output in specified format.
Lists programs or texts.
Acts as plotter.
Second Drive for Floppy Disk Read/Write Unit
Enables second floppy disk to be used, increasing storage and file handling capacity (programs, data or text).
Olivetti Standard Peripheral Interface (IPSO)
For data management and exchange between central memory and IPSO peripheral units.
System can be supplied with one or two interfaces; each enables up to 4 input, 4 output, or 4 input/output units to be connected simultaneously. Maximum exchange speed: 20,000 cps. Input/output: serial by character, parallel by 8 + 1 bits.
Moving Head Disk Unit interface (DCC 6609)
Enables connection of DCU 7292 moving head disk external mass memory unit.
Average access time: 50.5 msec (including latency time).
Transfer speed: 300 kbytes/sec. Asynchronous Line Control Unit For connection to data transmission lines (time-sharing) and compatible EIA RS 232 C (CCITT V 24) peripheral units.
External Connections iP50 Peripherals
- high speed impact printers
- punched tape readers - tape punch
- punched card reader
- cassette tape units
- measuring instrument adaptor
- plotters
- computer compatible magnetic tape unit
- input/output typewriter.
Moving Head Disk Unit (DCU 7292) Random access external mass memory for data, programs and operating systems.
Unit consists of two disks, one fixed and one removable (total capacity: 9.8 Mbytes).
Average access time: 50.5 msec (including latency time).
Transfer speed: 300 kbytes/sec. Serial Peripheral Units
All compatible EIA RS 232 C
(CCITT V 24) serial peripherals. Time-sharing
The P 6060 can be used as a time-sharing terminal connected to remote computers, through the asynchronous line control unit. Representation of Variables in Memory
Simple numeric variables, and each element of array numeric variables, are represented in floating point with double or single precision as requested:
- double precision (8 bytes), with 13 digit mantissa, 2 digit exponent (from -99 to + 99) and sign
- single precision (4 bytes), with 6 digit mantissa, 2 digit exponent (from - 63 to + 63) and sign. Simple alphanumeric variables and each element of array alphanumeric variables are represented in 16 bytes. User may request any representation from one byte to a maximum of 1023 bytes.
Programming Language
P 6060 uses extended version of BASIC (Beginners All-purpose Symbolic Instruction Code) compatible with ANSI and ECMA Standards.
Main features:
- input format in fixed point and floating point
- output format automatically in integer, fixed or floating point, depending on order of magnitude
- output formats selected by program
- immediate execution of statements in calculator mode
- handles external files of various types (data, program, text)
- sequential or random data files
- simultaneous program access to data files
- subroutines and functions (single-line or multi-line)
- user definable keys
- program chaining
- strings variables
- matrix operations
- plotting functions for integrated printer.
Operating System
Operating system resides on floppy disk, modular in structure, to allow dynamic loading into central memory. Organization:
- basic system: modules automatically loaded into reserved areas (32 K) in central memory
- extended system: modules for logical extension of system (handling strings, matrices, etc.).
Main functions of basic system:
- interpretation of machine language
- compilation of programs
- interpretation and execution of system commands (program editing, management of program libraries and data, etc.)
- compilation of statements in calculator mode
- management of integrated input/output units
- handling, under program control, of data files resident in external memory
- execution of utility programs (disk copy, file copy, disk reorganization, etc.).
Main functions of extended system:
- handling strings
- matrix manipulation
- use of integrated printer for plotting
- management of input/output operations with IPSO peripherals - use of system as terminal.
