The HEX keypad front panel with the LED driver daughter board in place. The fascia artwork was inkjet printed on premium glossy photo paper at 600 dpi then protected by clear self-adhesive vinyl film used to cover book jackets.
N8VEM ribbon cable. From left to right, the ribbon cable lines are connected to pins 1 (black), 2 (white), 3 (gray), 4 (purple), 5 (blue), 6 (green), 7 (yellow), 8 (orange), 9 (red), 10 (brown).
Pin 1 on the header is marked by a triangle on the solder mask silk screen, and the pins are numbered 1, 3, 5, 7, 9 on the bottom row (toward the components), and 2, 4, 6, 8, 10 on the top row (away from the components)
The Indy, code-named "Guinness", is a low-end workstation introduced on 12 July 1993. Developed and manufactured by Silicon Graphics Incorporated (SGI), it was the result of their attempt to obtain a share of the low-end computer-aided design (CAD) market, which was dominated at the time by other workstation vendors; and the desktop publishing and multimedia markets, which were mostly dominated at the time by Apple Computer. It was discontinued on 30 June 1997 and support ended on 31 December 2011.

Retrocomputing (a portmanteau of retro and computing) is the use of early computer hardware and software today. Retrocomputing is usually classed as a hobby and recreation rather than a practical application of technology; enthusiasts often collect rare and valuable hardware and software for sentimental reasons. However some do make use of it.[1] Retrocomputing often gets its start when a computer user realizes that expensive fantasy systems like IBM Mainframes, DEC Superminis, SGI workstations and Cray Supercomputers have become affordable on the used computer market, usually in a relatively short time after the computers' era of use.

Con il termine retrocomputing si indica una attività di "archeologia informatica" che consiste nel reperire, specialmente a costi minimi, computer di vecchie generazioni, che hanno rappresentato fasi importanti dell'evoluzione tecnologica, ripararli se sono danneggiati, metterli nuovamente in funzione e preservarli.

8BASIC (C) is a BASIC interpreter developed by manufacturer G.G in 2010 for the homemade Z80/AM95 8 bit NANO COMPUTER.
38 "INPUT A " ; ask the user to enter the numeric value of variable A
39 "INPUT T$" ; ask the user to enter the string value of variable T$
40 " CLS " ; clears (blank) the 16-segment LED displays and reset (0) the 7-segment ones
41 " CLEAR " ; reset variables to their default type value
42 "PRINT A " ; display the numeric value of variable A
43 "PRINT T$" ; display the string value of variable T$
44 "PRINT+T$" ; display and scroll the strings T$ and consecutives till encountering # char
45 "PAUSE T " ; suspend the program execution. Value of T is the time in ms to pause
46 "BEEP T,F" ; generate a tone. T is the tone duration (ms). F is the tone number (max 7)
47 " IN (A) " ; assign to variable A the binary value input from the 8 bit parallel port
48 " OUT (A)" ; output binary value of variable A to the 8 bit parallel port
49 "A=PEEK X" ; assign to variable A the byte value at the X memory location
50 "POKE X,A" ; write byte value of variable A into X memory location
51 "SYS X " ; branch (and jump back) to the machine language program at the X location
Each statement is precompiled as much as possible to make the interpreter run faster and it always occupies 16 bytes.
Statements allow you extreme flexibility. For example a FOR...TO..NEXT cycle can be easily written as:
LET I=+1.00000
LET U=+1.00000
LET T=number of cycles
N:
cycle
I=I+U
IFT>=I:N
END
Due to the internal RAM memory structure, the maximum size of the 8BASIC program has been set to 488 lines, which will fit the first 8K RAM chip.
Understanding Oric by Ian McLean, published in 1984 by Prentice-Hall International. This is another of those books designed to be an alternative to the official manual and this example was suitable for both the Oric 1 and Oric Atmos as evidenced by the sticker on the front.

There's a cutting from an old computer magazine in the box where someone wrote a very angry letter saying that the position of the return key is just fine and it should not be mentioned in reviews.

AKA the "Executive 64"; the C64 reengineered into a portable. No battery, a small CRT screen, and it weighs quite a bit, but for the early 80s, it was pretty impressive.
