The A9home is a small-form-factor desktop computer that runs RISC OS Adjust32. It first announced at the 2005 Wakefield Show, and following the withdrawl of the Iyonix RISC PC was the only hardware to be manufactured specifically for the RISC OS marketplace.
Measuring 168x103x53mm in size, it runs on a 400 MHz Samsung ARM9 processor. It has 128MB SDRAM main memory and 8MB video RAM. The internal hard disk has a capacity of 40GB. The front panel features two USB 1.1 ports, and microphone and a headphone sockets. On the rear, it has two USB 1.1 ports, two PS/2 ports, a 10/100 BaseT network port, an RS-232 serial port, and a power connection socket. Like the Mac mini, it is powered by an external PSU (5V, 20W). The front panel also features a power/reset switch, a status/health indicator, and a drive activity indicator LED. The A9home is not designed to be internally expanded.
The A9home can use a program called Aemulor to emulate older 26-bit applications. This was originally developed for Castle's Iyonix PC.
The Sony Data Discman was an electronic book player launched by Sony Corporation in 1990.
It was marketed in the United States towards college students and international travelers, but had little success outside of Japan. The Data Discman's purpose was for a quick access to electronic reference information on a pre-recorded disc. Searches for information were entered through a QWERTY-style keyboard and the "Yes" and "No" keys. A typical Data Discman model had a low resolution small grayscale LCD, CD drive unit, and a low-power computer. Early versions of the device were incapable of playing audio CD discs. Software was prerecorded and usually feature encyclopedias, foreign language dictionaries, novels, and the like.

This green-screen serial terminal by C.Itoh Electronics Inc. is a rebadged DEC VT-101 terminal.
The Black Watch was launched in September 1975 by Sinclair Radionics, later Sinclair Research, the company behind the ZX81 and ZX Spectrum. It cost £24.95 ready-built or £17.95 as a kit. It had a red LED display and was marketed by the company as follows:
'if that [the technical description] sounds technical, think of the outcome: a watch with no moving parts, a watch with nothing to go wrong, a watch which gives accuracy never achievable by the most precise mechanical engineering.'
The Black Watch, however, was riddled with problems. So many were returned that the company made a huge loss and would have been bankrupted but for a government subsidy. However, the Watch is a good early example of Sinclair's interest in aesthetically pleasing electronic products.
Our Black Watch comes in its original display case.
Assorted boards removed from the Ferranti/Cambridge university Titan computer. Note the use of germanium transisitors and 'hearing aid'-style triode valves.
A third-party VGA adapter for the Sega Dreamcast. Plays Dreamcast games on VGA monitor or television.
This media centre PC by Elonex was released in 2008 and aimed to replce both the home entertainment system and computer with a single unit. It runs Microsoft Windows XP Media Centre and can record one video stream while watching another with its dual TV tuners. The Nvidea graphic card supports both DVI and component output. The Intel Pentium D processor is supported by 1GB RAM and a 200GB hard disk drive for recording TV shows. The DVD drive supports rewritable discs. Hidden behind the fold-down front panel are USB and media card ports.
The MicroVAX II, was a mid-range MicroVAX introduced in May 1985. It ran VAX/VMS or, alternatively, ULTRIX, the DEC native Unix operating system.
It used the KA630-AA CPU module, a quad-height Q22-Bus module, which featured a MicroVAX 78032 microprocessor and a MicroVAX 78132 floating-point coprocessor operating at 5 MHz (200 ns cycle time). Two gate arrays on the module implemented the external interface for the microprocessor, Q22-bus interface and the scatter-gather map for DMA transfers over the Q22-Bus. The module also contained 1 MB of memory, an interval timer, two ROMs for the boot and diagnostic facility, a DZ console serial line unit and a time-of-year clock. A 50-pin connector for a ribbon cable near the top left corner of the module provided the means by which more memory was added to the system.
Our example features a TK50 cartridge tape drive and an RD54 Winchester hard drive - which unfortunately may be faulty. The machine is running VMS 5.4.
This dual 8" floppy disk drive was produced by Pertec Computer Corporation. It was used with an Altair 8800b and has a similar case styling.
The HP 110 computer (also known as the HP Portable) was released by Hewlett-Packard in 1984. It ran MS-DOS on a Harris 80C86 processor, running at 5.33MHz. It had 272KB RAM and an 80 character by 16 line monochrome liquid crystal display. The MS-DOS 2.11 operating system and built-in application programs (MemoMaker, Terminal Emulator and Lotus 123) were all stored in ROM.
This 84-key keyboard was supplied with the original IBM 5150 PC. It uses a 5-pin DIN plug and is not electrically compatible with the later AT and PS/2 computers. The keyboard protocol is one-way and the keyboard therefore lacks the caps/numeric/scroll-lock LEDs that would later be introduced.
Part number: 1501105
This blade enclosure by RLX Technologies can hold up to 24 blade units in a 3U rackmount chassis. Each blade is an independent computer running at 800MHz with dual hard disks. Each 24 blade unit originally retailed for $10,000.
This blade centre unit was originally used at Hinxston as part of the Human Genome Project.
This expansion cartridge for the Sega Saturn by Joy Tech Europe adds 8MB memory and allows game saves.
This third-party RAM expansion for the Sega Saturn features a switch allowing it to be mapped as either a 1MB or 4MB RAM expansion. The 1MB option would be used for games that did not support running with the extra memory.
This expansion card connects to a (typically server-grade) PC via the PCI-X bus (not to be confused with PCI Express). It connects to SCSI storage devices through either the internal or external 68-pin connectors.

This personal computer from NEC Corporation was released in Japan in 1985. Like other machines in the PC98 range, it was not entirely compatible with the IBM Personal Computer despite using a similar processor. The BIOS, I/O ports, and graphic system are all very different from the IBM computer. Despite this, it could still run specially modified version of DOS and Windows. In Japan the PC98 computers were extremely popular, with thousands of software titles released - many of them games, despite it being originally positioned as a business system.

The 8595 is an early model 95, lacking the protective plastic flap that covers the power button in later models. The model 95 uses the same case as the model 85, but with redesigned internals. It is the largest Microchannel machine built by IBM that did not include non-Microchannel expansion slots.
This 3.5" exteranl floppy disk drive by Watford Electronics is designed to connect to a BBC Microcomputer DFS or ADFS. Under DFS it presents itself as disks 0/2. It run in 80-track mode.
This Cumana 5.25" floppy disk drive is powered by the BBC Micro and presents itself as disks 0/2. Switchable between 40 amnd 80 track modes.
The TRS-80 Expansion Interface (catalog number 26-1140) is the basic model, shipping with no additional RAM installed. Two other variants were also sold with catalog numbers 26-1141 and 26-1142, containing 16K and 32K or RAM respectively.
In addition to allowing extra RAM to be fitted to a TRS-80, the Expansion Interface also provides:
- DIN jacks for two cassette records
- Line printer card-edge for connection to Radio Shack Line Printers and other suitable parallel interface printers
- Min-Disk card-edge for connection of up to four Radio-Shack Mini-Disk Drives
- Expansion board card edge for use with the RS-232C Interface (or other custom designed PCB)
- Bus card edge, which duplicates the signals present at the TRS-80 card edge.
In addition to these connections, the Expansion Interface provides a 25mS heartbeat interrupt to the computer (RTC).
The Expansion Interface is not compatible with a Level I TRS-80, only Level II.
The TRS-80 Mini Disk 26-2161B is identical to the 2160B unit, except it lacks the terminating resistor set and is not supplied with a connecting ribbon cable. User's were intended to purchase one 2160B unit initially and buy additional 2161B drives to expand to the maximum four drive system.
The TRS-80 Mini Disk is a small version of a floppy disk. The disks are 5.25" in size ('small' in comparison to the 8-inch disks that were commonly used on larger systems at the time). The number 0 disk can contain about 58,8000 bytes of file space, and each additional disk will contain 83,060 bytes of file space.
To use the TRS080 Mini Disk, you need a 16K Level II BASIC TRS-80 microcomputer or a 16K Level I BASIC TRS-80 microcomputer which has been modified to Level II BASIC. You will also need the TRS-80 Expansion Interface that is distributed under three different part numbers (the difference in the three part numbered units is the amount of additional RAM they provide).
The 26-1160B Disk Drive is supplied with a ribbon interconnect cable and is fitted with a set of termination resistors. Therefore in a multi-drive system, the 1160B unit should be furthest from the computer end of the cable. Additional Disk Drives should be of the 1161B type, which are not fitted with the termination resistors.
This dual disk drive unit by Akhter sits over the top of the BBC Micro, providing two 5.25" disk drives (individually switchable between 40 and 80 track mode). It also provides a safe place for a monitor such as the Microvitec Cub.

This external floppy drive was manufactured by Apricot Computers.
This 8-bit ISA expansion card from Western Digital supports two MFM-format hard drives with up to 16 heads and 1024 cylinders each using the ST506/ST412 interface. It is jumper configurable for secondary addressing and default drive tables. The built in ROM BIOS supports non-standard drive types, virtual drive formatting, dual drive operation, bad track formatting and dynamic formatting. This board features a power connector for filecard applications and it will also operate in AT systems.
This generic floppy controller card was part of an Elonex XT-clone PC. It uses the standard UM8272A controller chip capable of controlling up to four floppy drives. Somewhat unusually, the card has an external DC37 connector allowing the use of the second pair of drives (most manufacturers omitted the external port, assuming that users would not have more than two floppy drives in their PC).
This 8-bit ISA floppy controller card is a generic Taiwanese clone. It can control up to two floppy drives through the internal edge-connector using a UMC8272A floppy controller chip. The board has a position for an external DC37 connector to control two more drives but the manufacturer chose not to populate it. The previous owner has soldered pin headers onto the reverse of the card so the two extra drives could be mounted inside his computer.
Display is 12 digits, green vacuum-fluorescent tubes, with half-height zero.

8-bit CMOS processor
The Compaq SLT/286 (1990), prices starts at $5,399.
The machine offers a bright high-resolution display that supports the VGA video standard, the first laptop with that feature. It has a 12-megahertz 80C286 processor, a new low-power chip that is among the faster 80286 microprocessors, and it is certainly capable of handling most applications. And it has a detachable keyboard, another first among laptops.
It is 8 1/2 inches deep - 2 to 3 inches less than the other leading laptops at the time
The SLT/286 provides mass storage in the form of a 20-megabyte or 40-megabyte hard disk drive. The shock-mounted drive is a new design that can withstand up to 80 G's of impact, or a ride in the trunk of a New York City taxi, whichever comes first. Data is transferred through a high-capacity (1.44 megabyte) 3.5-inch diskette drive. An optional 2,400-baud internal modem is $599.
At 14 pounds, including the battery and the hard disk, the SLT/286 strains the definition of laptop. Still, it is five pounds lighter than Compaq's lunchpail-shaped Portable III, a significant difference among portables. Most important, it runs for three hours on one battery charge. An optional backup battery pack ($129) weighs two pounds.
One drawback of the machine is that it does not support color, but then neither does any other laptop. (High-resolution flat-panel color displays will begin arriving next year.) Another surprise is that Compaq, which has forged its reputation for high-performance machines around the 80386 microprocessor from the Intel Corporation, did not introduce an SLT/386. While the 12-megahertz 80C286 is a better-than-average chip, it is no match for the 386 chip. Michael Swavely, Compaq's vice president for marketing, suggested in an interview that the power demands of the 386 chip had reduced the SLT's battery life to unacceptably short periods. The fast 286 chip, he said, offered the best balance of performance and battery life.
