Zilog Z80B 4.00MHz CPU (1983)
This CPU was taken from the motherboard of a defective KAYPRO II transportable "luggable" computer I salvaged for spare parts. |

AMD 386DX 40MHz CPU on interposer (1994) |
|
Intel 80486SX 25MHz CPU on interposer (CPU: 1989) (Interposer version: 1992) |
|
Intel 80486SX2 50MHz CPU (1992) |
|
Intel Pentium Pro 166MHz CPU (1995) The Pentium Pro was Intel's first dual-core CPU. Ten years later, Intel released a new generation of dual-core CPUs and called them the Pentium D. These CPUs had clock speeds of 2.8GHz and faster. |

Intel Pentium Overdrive 83MHz Factory Sealed Package In addition to the 83MHz Intel Pentium Overdrive featured above, this original factory sealed full package has also become a part of the Dan's 20th Century Abandonware collection. This Overdrive processor increases the speed and performance of 486 PCs. This package was donated to Dan's 20th Century Abandonware by Michael S. from IL USA. Thank you, Michael! |

1982 IBM 6360 8'' dual-floppy drive unit for IBM DisplayWriter word processors
A rare find today, this dual-drive 8" floppy disk unit was not able to be read/write tested by D2CA at this time. A power-up test was conducted by connecting the power cord to the power supply of D2CA's IBM 5160 8088 Personal Computer (image 16). The IBM 6360 has a power cord connector that connects to older computer power supply power out sockets, drawing power in much the same way as USB devices do with modern computers. The IBM 6360 successfully powered on and the drive motors ramped up normally. Disk drive testing will be done if D2CA is able to acquire compatible hardware for this unit. While it looks like it, contrary to popular belief this is not a toaster! This rare piece of computer history was donated to Dan's 20th Century Abandonware by Daryl C. from UT USA. Thanks, Daryl! |

Scorpius 22 Numeric Keypad
One of the major problems that nearly all laptop and notebook computers have is the lack of a numeric keypad. The numeric keypad is sacrificed to allow for more compact portability. This Scorpius 22 Keypad is a 1994 model with a 9-pin serial interface, a 9-to-25-pin serial adapter, and DOS/Windows 3.1 drivers on a floppy disk. This package is still sealed in its original shrinkwrap. This keypad gives laptop and notebook computers that lack a numeric keypad nearly all the functionality of a full-size 101 keyboard. Qtronix continues to sell Scorpius numeric keypads, including models with PS/2 and USB interfaces. |

Central Point Software Deluxe Option Board (1987)
For nearly the entire decade of the 1980's, many software companies encoded their software installation disks with copy protection schemes -- making duplication of these disks virtually impossible using conventional disk copying programs of the day, such as the DOS DISKCOPY utility. A hardware/software combination, the CPS Deluxe Option Board overcomes two major computing stumbling blocks. It is an ISA expansion card that employs a hardware chipset to override a computer's floppy disk controller and, using accompanying software utililities, can copy virtually any copy-protected floppy disk. The Central Point Software Deluxe Option Board can also format and read Macintosh 400K and 800K disks in a PC's 3½" floppy drive. Additional provided utilities allow the copying of files from Macintosh double- density disks to a PC, and PC files to be copied to Macintosh double-density disks. |

QIC Magnetic Tape Cartridge
Before the age of CD burners, DVD burners, and USB "flash drives," in the early 1990's the only ways to back up mass amounts of data on personal computers was to utilize a backup software program that spanned data across floppy disks or a technology at the time known as QIC magnetic tape cartridges. Default QIC tape cartridges of the day had a capacity of 120MB of uncompressed data, like the tape cartridge shown in the picture to the left. Internal QIC tape drives shared a PC's floppy controller and external QIC drives shared a PC's parallel port. |

Memory - SIMMs & DIMMs
30-pin SIMM memory modules were developed to replace individual memory chips found in 8088 XT and early 286 PC models. They would be used in later 286, 386, and even early 486 PCs. 72-pin SIMMs would be used in later 486 and first-generation 586-class PCs. In the late 1990's a new type of memory, called RAMBUS, was developed. It was a high-speed memory, but expensive and required a terminator card for each RAMBUS DIMM. A newer, less expensive type of memory called DDR would later replace RAMBUS. These items span the beginning of 30-pin SIMM memory modules to the end of 72-pin modules to the beginning of RAMBUS modules. The top module is a 30-pin 256K (that's kilobyte) SIMM. The second module from the top is a 72-pin 128MB SIMM. The last two are a 128MB RAMBUS DIMM and its accompanying terminator board. |

Snappy Video Snapshot Copyright © 1995 Play, Inc. This is the first release of Snappy Video Snapshot. A unique hardware/software combination, Snappy Video Snapshot is designed to capture still images from a video source -- a VCR, camcorder, or other video output device. The hardware device plugs into a computer's parallel port. A video cable, included with the unit, is plugged into the VIDEO IN port and the other end of the video cable is plugged into the video source device. A 9-volt battery powers the hardware unit. The video capture software, version 1.0, is a 16-bit Windows 3.1x program. But the first release of the Snappy Video Snapshot device was not without its inconveniences. While the unit had a "pass-thru" for the video signal to go out to a device, such as a television set, it did not have a parallel pass-thru to allow sharing a printer. A major inconvenience with this version of Snappy Video Snapshot is it is powered by a 9-volt battery. A 9-volt alkaline battery would only last five to six hours running the graphics-intensive tasks of displaying the video signal, capturing images, and rendering images in different brightness, contrast, and sharpness settings. Tired of wasting money on batteries, I bought a 9-volt power adapter, cut off the end, cut off the end of the 9-volt battery connector in the Snappy Video Snapshot unit, and spliced the wires together. This allowed me to plug the adapter into an electric outlet for unlimited power for the Snappy device. This unit can still be used today to capture still images from a video source. |
