The first version of the TRS-80 Color Computer has a calculator-style "chiclet" keyboard, and was available with memory sizes of 4K (26-3001), 16K (26-3002), or 32K (26-3003). This is the 16K model and therefore shipped with Microsoft Color Basic instaled. No monitor was supported; instead the user was expected to connect the computer to a regular TV.
The IBM dB Adapter is a battery-operated electronic device designed to extend the dB measurement capabilities of the IBM VOM 1749231. The dB Adapter has a range of -50 through 0 (zero) dB, in increments of 10 decibels.
This internal tape drive is designed to accept DC 6250 data cartridges, each containing 1020 feet of magnetic tape. The total storage capacity is 250MB. The tape drive is sized to fit in a standard half-height PC drive bay and connects to a Wangtek 30631-001 SCSI controller card (8-bit ISA bus).
This 8-bit ISA card by Quest Standard Telematique is powered by a Motorola 68000 microprocessor and was possibly used to connect to ISDN telephone lines.
This 8-bit ISA expansion card for the PC provides on 9-pin RS232 serial port. The port can be assigned to any of the COM1-COM4 I/O addresses using the jumper block at the top of the card. The serial controller is an INS8250N-B chip.
The large areas of unpopulated components are to support a 25-pin parallel port, which would have been assignable to any of LPT1-LPT3 I/O ports using the right side of the jumper block.
The card's FCC ID of identifies the manufacturer as Taiwan Mycomp Corporation.
The Quinkey was a cut-down version of the Microwriter MW4. It was not a standalone unit and was marketed as ana alternative keyboard for the BBC Micro computer. It was designed around the concept of 'chording' multiple keypresses together to allow full-speed typing with only one hand. Up to four Quinkeys could be connected to a single computer using the Quinkey Interface Unit, which connected to the BBC Micro's Analogue port.
Although praised by reviewers for the comfort and high speed of typing obtained with only a few hours training, the Quinkey was not a massive commercial success.
The ZX Interface 2 was released in 1983 by Sinclair Research for the ZX Spectrum home computer. It connected to the expansion port of the ZX Spectrum and features two joystick ports and a ROM cartridge slot.
The cartridge slot allowed instant load times, but due to it's limited size (only supporting 16KB of ROM without additional bank-switching hardware) only ten games were commerically released in this format.
The joystick ports did not use the Kempston joystick protocol and were therefore incompatible with previously released software. The first joystick was mapped to keys 6-0 and the second joystick to keys 1-5.
A pass-through expansion connector is present on the rear of the unit, but not all pins from the computer were exposed - enough only for connecting a ZX Printer.
The Sovereign was one of the last calculators to be released by Sinclair before the company refocused on the personal computer market. It was released in 1976 and can display eight digits in its red LED display. It features the usual four arithmetic functions plus square, square root, percentage, and memory. Because the case was made of pressed steel instead of plastic it was available in a variety of styles, including black painted, chrome plated, silver plated, and gold plated.
The Sinclair Executive Memory is a four-function calculator introduced by Sinclair Radionics in 1973. It uses eight red LED digit displays and is powered by four button cell batteries. The low power consumption required to run off such a small power source was obtained by pulsing the power supply to the electronics.
Syncro Express is a high speed floppy disk backup system for the Atari ST. Data is transferred directly from source to target using the Syncro Express Interface, producing a single sided copy in less than 23 seconds and double sided in under 44 seconds. Note that a secondfloppy disk drive is required.
The GNT 4601 is a combination paper tape reader/punch device. It handles serial data at speeds of up to 1200 baud, and all data and control signals conform to RS232C/V24 and RS423. There is also a current loop facility and a parallel input for the punch.

Anderson Jacobson was primarily a manufacturer of acoustic coupler modems, but also manufactured printing terminals designed to replace teletypes. Anderson Jacobson began early in 1967 as a manufacturer of one of the first acoustic data couplers. By 1973, the company had acoustic coupler products that transmitted at 150, 300, 450 and 1200 baud. The 1200 baud acoustic coupler believed to be the only one of it's kind in 1973An acoustic coupler is an interface device for coupling electrical signals by acoustical means — usually into and out of a telephone instrument.
The link is achieved through converting electric signals from the phone line to sound and reconvert sound to electric signals needed for the end terminal, such as a teletypewriter, and back, rather than through direct electrical connection.
It is designed for acoustically coupling a telephone to a data terminal for the purpose of transmitting or receiving messages, where the telephone handset is placed on a bracket mounted directly on the chassis of the terminal. Isolation of transmitting and receiving acoustic links is provided by a pair of resilient cups, one for each link. The inside contour of each cup is adapted to provide a supporting annular ledge for one end of the telephone and an airtight seal over the transducer thereof. An annular recess below the ledge is formed to receive and tightly hold a flange of a receiving or transmitting transducer. Each cup is mounted on the bracket by a resilient flange. The flange is connected to the cup by a sleeve which is turned in at the top to form an inverted auxiliary cup with the base of the main cup protruding through the bottom of the auxiliary cup. In that manner, virtually complete acoustic isolation is provided by the cup from the surrounding air and bracket.
Our coupler has a serial number of 30783 and was kindly donated by William (Bob) H Williams

Produced by Sun Microsystems in 1996, the JavaStation-1 was a Network Computer (NC) intended to run only Java applications.
The hardware is based on the design of the Sun SPARCstation series of UNIX workstations. As a Network Computer, the JavaStation lacks a hard drive, floppy or CD-ROM drive. It also differs from other Sun systems in having PS/2 keyboard and mouse interfaces and a VGA monitor connector.
The JavaStation-1 (part number JJ-xx), codenamed Mr. Coffee was the first production model and was based on a 110 MHz MicroSPARC IIe CPU. The computer was housed in a cuboidal Sun "unidisk" enclosure.
The JavaStation range of computers would ultimately be superceded by the SunRay thin-client system.
This paper tape reader and panel were used in a BCL Susie electronic computer.
The Nimbus PC was introduced by Research Machines for use in the education market. It sold with 192KB RAM, a single 720 KB floppy drive, and extended sound and graphics. It could be expanded to 1 MB of RAM, dual floppy drives, and up to a 160MB hard disk. The Nimbus was also designed as a network station and came with built-in Piconet and ethernet ports.
The Nimbus ran a modified version of Microsoft MS-DOS 3.10 that would not run on a standard PC. Although an IBM emulator software allowed some standard PC programs to run, only software specifically written for the Nimbus was able to take advantage of the improved sound and graphic features. However, RM and third-parties released numerous languages and educational software that fulfilled most school needs.
This 'all-in-one' computer system was released by PoloMicrosystems in 1984. It was marketed as a machine that contained everything you needed to run a small office - including items that other computer manufacturers would sell seperately such as monitors, disk drives, a printer, and software.
It featured two microprocessors: an Intel 80188 to run DOS and PC-compatible software; and a Zilog Z80 to allow it to run CP/M software.
It also included a modem to allow it to dial-up to online services. One notable feature was the button on the upper-right of the keyboard. This placed it into a low-power 'sleep' mode from which it would wake periodically to dial-up to the user's mail service. If any unread messages were found, the Polo would return to sleep mode with a flashing LED to alert the user to their new mail.

An Apricot-branded CRT monitor for the Apricot range of computers. White, 10" display.
The Apricot F2 was a business machine marketed by Apricot in 1985. It was similar in specification to the F10 but shipped with two floppy drives instead of a floppy/hard drive combination.
Compared to its' predecessor, the F1, it included an extra expansion slot, more memory and larger storage capacity. Like the F1, the F2 and F10 had an infra-red interface for the keyboard and the mouse/trackball (the same infra-red mouseball pointing device used with the Apricot Portable).
The F2 and the F10 use an Apricot-modified version of MS-DOS, so they were not 100% IBM compatible. They were provided with a nice graphical and iconized interface called Activity. Integrated were a desktop, and software including a wordprocessor, communication, painting and Basic. They were also sold with GEM Write, GEM Paint and the GEM desktop.
The PET has a special place in the history of micro-computers, as it was one of the biggest sellers in the 1979 / 1980 period, when computers were aimed at both the home and business market. Many people instantly recognise the PET as it stood out from the usual ' terminal plus box' computer.
This was the first PET model, launched in 1977. It was a popular machine and found many admirers, from educational use, hobbyists, and some business users. The first machines only had 4K of RAM, mine has 8K, but even this was very limiting so several third-party memory expansion boards were available to take the memory up to 32K. It has a built in system ROM (6K) and BASIC (8K), and with additional memory could run 6502 assemblers and even compilers The screen could display upper and lower case letters, and an attractive range of graphics symbols. These features encouraged a large library of software to be written.
The 2001 model was found to be slow in updating its display, until someone discovered a way of speeding up the graphics routines with a POKE to memory. This was fine, but on later machines the graphics hardware was improved and the same POKE caused the screen to go blank and was know as 'the killer POKE'.
Some of the chips used on the motherboard:
Main RAM 16 x MOS MPS 6550 (8K)
Main ROM 7 x MOS MPS 6540 (14K)
Video RAM 2 x MOS MPS 6550 (1K)

TRS-80 Microcomputer System Model III
The Model III is basically an upgrade of the Model I, which was released three years earlier. It has the same CPU, but it is faster, has more memory, and the floppy drives hold twice as much data, although the Model I could be upgraded to some of these features.
The major reason for developing the Model III was because the FCC had just instituted new regulations about RF emissions generated by computers and other electronic devices. The Model I was completely unshielded and was unable to pass the emission restrictions.
The Model III system is entirely self-contained. The original Model I had edge-type connectors with ribbon cable connecting the keyboard to the (optional) Expansion Interface, as well as the floppy drives. This type of connection is very unreliable, and led to the occasional system crash or lock-up.
Introduced July 1980
The improvements of the Model III included built-in lower case, a better keyboard, and a faster (2.03 MHz) Z-80 processor.
This Macintosh SE/30 was once owned by Douglas Adams.
The MZ-700 was launched in Japan in October 1982, but did not appear in the U.K. until October 1983. lt was the first Sharp home Computer with colour, but it came without a built-in display unit; instead, sockets were provided for a colour TV or an RGB Monitor; or a B/W TV set or a Mono Monitor. lt also had a built-in printer I/F with a switch which allowed you to run the MZ-1P01 4-pen plotter-printer or a more standard MZ-80P5( K ) dot-matrix printer.
Thus, with its clock speed of 3.5MHz, the MZ-700 seemed to meet many of the criticisms levelled at the MZ-80A when it was launched in June 1982. But it was still only a halfway-house - the printer I/F only suited Sharp printers, the screen was only 40 columns, and to run disk drives you needed an extra interface of some kind.
The MZ-700 was reviewed in the PCW Magazine in February 1984. By then most of the competing machines had high-res graphics, and the reviewer was hard on the MZ-700 over that. But he was impressed by the alternative languages available, and concluded that the MZ-700 was ‘worthy of serious consideration‘. The prices below come from this review; significantly, there is no mention of disk drives:

All these are INC VAT; in the same Magazine: BBC Model B £350, Commodore 64 £240
Model Numbers :
- MZ 711 was the basic model without any peripherals
- MZ 721 has an integrated tape recorder
- MZ 731 has built-in plotter and tape recorder
The Olivetti M290 was a personal computer based around the Intel 80286 processor. Unlike standard IBM machines, it was designed around a largely passive backplane. The majority of what the modern user would consider 'the computer' was based on an add-on expansion card. This 'processor card' held the CPU, main memory, optional maths co-processor, and keyboard interface. Other expansion cards handled external connectivity such as video, serial, and parallel I/O. The standard M290 shipped with a video card and monitor compatible with the IBM EGA standard. Various storage options were available, ranging from one 5.25" floppy drive, to dual floppy drives plus a 40MB hard disk unit.
This machine was owned and used by Chris Turner who was Chief Engineer at Acorn Computers Ltd.
