The IBM System/360 Model 40 was a mid-range member of the IBM System/360 family. It was announced on April 7, 1964, shipped in 1965, and withdrawn on October 7, 1977. It was announced on April 7, 1964, shipped in 1965, and withdrawn on October 7, 1977.
The user guide engraved into a model of the Antikythera Mechanism. User guides have been found with ancient devices. One example is the Antikythera Mechanism, [1] a 2,000 year old Greek analogue computer that was found off the coast of the Greek island Antikythera in the year 1900. On the cover of this device are passages of text which describe ...
The first computers bearing the Macintosh Quadra name were the Quadra 700 and Quadra 900, both introduced in 1991 with a central processing unit (CPU) speed of 25 MHz.The 700 featured the case dimensions as the Macintosh IIci but vertically oriented as a mini-tower, with a Processor Direct Slot (PDS) expansion slot, while the latter was a newly designed full-tower case with five NuBus ...
Model Description WD1402A The first single-chip UART on general sale. Introduced about 1971. Compatible chips included the Fairchild TR1402A and the General Instruments AY-5-1013. [11] Exar XR21V1410 Intersil 6402 CDP 1854 (RCA, now Intersil) Zilog Z8440 Universal synchronous and asynchronous receiver-transmitter (USART). 2000 kbit/s.
The quad serial gigabit media-independent interface (QSGMII) is a method of combining four SGMII lines into a 5 Gbit/s interface. QSGMII, like SGMII, uses low-voltage differential signaling (LVDS) for the TX and RX data, and a single LVDS clock signal. QSGMII uses significantly fewer signal lines than four separate SGMII connections.
VGA section on the motherboard in IBM PS/55. The color palette random access memory (RAM) and its corresponding digital-to-analog converter (DAC) were integrated into one chip (the RAMDAC) and the cathode-ray tube controller was integrated into a main VGA chip, which eliminated several other chips in previous graphics adapters, so VGA only additionally required external video RAM and timing ...

Most of the 800 Series laptops used the PowerPC 603e CPU, at speeds of 100 MHz, or 166 MHz in the 860 model, although the earliest 800 (Type 6020), the direct ancestor of the 850, used a 603 and was apparently only offered to developers. [3]
