The SPARCstation 2 uses a standard 50-pin SCSI interface and can house two 3 1/2" full-height disk drives. The SS2 also comes with a special auto-ejecting 1.44 MB floppy disk drive. Modern 80-pin Single Connector Attachment (SCA) SCSI drives can be used internally with an adapter, but the plastic drive sled used with 50-pin drives must be cut ...

Sun-4 is a series of Unix workstations and servers produced by Sun Microsystems, launched in 1987.The original Sun-4 series were VMEbus-based systems similar to the earlier Sun-3 series, but employing microprocessors based on Sun's own SPARC V7 RISC architecture in place of the 68k family processors of previous Sun models.
2 and manganese dioxide spinels through omission of the cobalt, whose negative temperature coefficient of resistance can encourage thermal runaway. The P–O bond in the (PO 4) 3− ion is stronger than the Co–O bond in the (CoO 2) − ion, so that when abused (short-circuited, overheated, etc.), the oxygen atoms are released more slowly ...
Experimental data shows 69% storage efficiency, with good storage capacity (over 1000 mAh/cm 2), low leakage (< 1 mA/cm 2) and high maximal discharge capacity (over 200 mA/cm 2). [34] By October 2014 the MIT team achieved an operational efficiency of approximately 70% at high charge/discharge rates (275 mA/cm 2 ), similar to that of pumped ...
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
The positive terminal has a maximum diameter of 3.8 mm (0.15 in); the flat negative terminal has a minimum diameter of 4.3 mm (0.17 in). [2] Alkaline AAA batteries weigh around 11.5 grams (0.41 oz), while primary lithium AAA batteries weigh about 7.6 g (0.27 oz).
The voltage of a single LiPo cell depends on its chemistry and varies from about 4.2 V (fully charged) to about 2.7–3.0 V (fully discharged). The nominal voltage is 3.6 or 3.7 volts (about the middle value of the highest and lowest value) for cells based on lithium-metal-oxides (such as LiCoO 2).
