Retro switch panel input option for the ELF2K. The artwork was inkjet printed at 600 dpi on premium photo paper which was then protected by clear self adhesive vinyl film used to cover book jackets.
Here's the inside. Yes, that's a passive backplane with a basic power supply and five cards. There's almost no logic in there, which makes sense, since this is a dumb modem. It just MOdulates the serial port levels to sound for the speaker and DEModulates the sound from the microphone to serial port levels.
It's built like something that's about to be launched to Mars.
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.

"+0.00000" ; 8BASIC standard numeric format is 6 digits plus sign and decimal dot
35 " LET T$=" ; (two lines statement) set the text variable T$ to the following string
"ABCDEFGH" ; 8BASIC standard string format is 8 chars (alphanumeric and special symbols)
36 "LET B==A" ; assign to variable B the numeric value of variable A
37 "K=INKEY$" ; make a program wait until a key is pressed and assign to K the pressed key
The Psion Printer II was a thermal printer with a built in rechargeable battery pack into which a Psion Organiser II could be inserted. The Organiser's top port was carried through to a port on the left hand side allowing for connection of accessories such as the Comms Link.
Here is a picture of the LZ64 out of the printer.
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.
Here's the null-modem RS-232 connector. The pins are (hopefully) clearly labeled. They're connected as follows (forgive the formatting)
N8VEM ------ 9-pin DSUB
2 (DSR) ------ 4
3 (RX) ------ 3
5 (TX) ------ 2
7 (DTR) ------ 6
9 (GND) ------ 5

Grazie all’iniziativa di Bruno Grampa, nella prestigiosa cornice del parco di Villa Toeplitz a Varese si è tenuto domenica 27 aprile 2003, presso il MUel- Museo Elettronico, la prima edizione di “Varese Retrocomputing”. La manifestazione si è articolata su un intero pomeriggio, a partire dalle ore 14:30, con interventi di esperti e collezionisti di retrocomputing che hanno presentato, in funzione, numerosi computer che hanno fatto la storia dell’informatica. All About Apple è stata presente con il simbolo dell’AMUG e del Museo, l’Apple Lisa, su cui è stato tenuto un keynote da Alessio Ferraro.
Il Comune di Forte dei Marmi, in collaborazione con Lilio Tarabella e il suo ‘Tarabella Hotel’, ci hanno offerto la possibilità di esporre, nella splendida cornice del Fortino di Piazza Garibaldi, una selezione delle macchine ‘storiche’ più significative nel percorso evolutivo di Apple.
Al Fortino sono arrivati l’Apple Lisa, il TAM (Twentieth Anniversary Macintosh), il Portable, il Macintosh 128k, i Newton, le Quicktake, il Set Top Box, l’Apple II, l’Apple //c, l’eMate, e tanti altri pezzi rarissimi del Museo All About Apple.

For the second straight year in a row, I've attended Codebits, a three day programming arts event/competition sponsored by Sapo/Portugal Telecom.
This year they had a Retro Computing area, to where event participants could bring their old computers and gaming consoles to show off how the past was, and I ended up being the official photographer of all the oldies! It was a lot of fun. You can see all the photos I took at Sapo Fotos.

In the early 1980's a boom in the UK home computer market led to many small outfits being set up to write software for the myriad of machines being produced. ByteLand were one of those, producing a small number of games for the Oric-1. This advert is from Personal Computer News Issue 30, of 1983.
Dating from the mid 1980s the Psion Organiser was one of the first pocket computers, this is one of the later models with a 4 line display and 64KB RAM. I had one of the 2 line XP models before this one.
Picture shows the LZ64 with the slide cover down and a comms link plugged into the top port. Alongside are 8k, 64k, 128k Datapaks and the Maths Pack. I also have a Datapak formatter somewhere.

The Schneider Euro PC is an all in one keyboard PC from 1988. Sporting a 8088 CPU running at 9.54 MHz, 512 KB RAM and a built in 720 KB 3.5" floppy drive. It had three graphic modes: CGA 620x200, Hercules 720x384, Text: 80x25

Here is an advertisement for it from the November 1989 issue of PC magazine:
8BASIC (C) is a BASIC interpreter developed by manufacturer G.G in 2010 for the homemade Z80/AM95 8 bit NANO COMPUTER.
Due to the strong mathematical support of the AM9511 processor, the interpreter offers floating-point arithmetic and is just hold in 3KB of EPROM memory.
The most interesting feature of the 8BASIC is that each statement is eight characters fixed-length, which exactly fits the computer's LED display.
