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.

Mostek cut a deal with a startup Zilog, in which Mostek provided fab resources to manufacture the Zilog microprocessors in return for second sourcing rights to the Zilog family. Mostek produced MK3880, the Zilog Z80 and a series of Z80 support chips, until Zilog built their own fab.

The HP Integral PC (or HP 9807A) was a portable UNIX workstation computer system produced by Hewlett-Packard, launched in 1985. It was based on the Motorola 68000 microprocessor (running at 8 MHz) and ran early version of the HP-UX operating system.

This program (written in Visual Basic) let my Z80 NANO COMPUTER communicate with an IBM PC Computer. You can choose either a serial or a parallel transmission for both the directions.
This 60 sec. video demo will show both Serial and Parallel transmission (TX and RX respectively)
In the demo the software will import the Assembly code from a third-party PC Z80 Simulator and then transmit it from the PC to the Z80 NANO COMPUTER ram. This trasmission in this demo is serial (RS-232). A 16 bit checksum is calculated on both the machines, transmitted to the Z80 machine and there checked. Serial transmission allows also a parity checking control. Then the program will re-import data from the Z80 to the PC, via parallel transmission this time. I have choosed a slow 10 ms handshaking to let you see the data while imported. A 16 bit checksum is calculated on both the machines, transmitted from the Z80 to the PC and here checked.
Hexadecimal data are manually copied from the program and pasted in a notepad to show you that data have been sent and received in a correct way.
The Apple IIc, the fourth model in the Apple II series of personal computers, was Apple Computer’s first endeavor to produce a portable computer. The end result was a luggable 7.5 lb (3.4 kg) notebook-sized version of the Apple II that could easily be transported from place to place.

The seven trimmers (all connected to a 555 oscillating circuit) are tuned to play the seven musical notes (Major Scale). The two quad analog/bilateral switch 4016 select the appropriate resistor, according to a seven bits word. The last bit is used to activate or mute the sound. The amplifier is just a simple general purpose low-power amplifying transistor (2N2222A).
