  The IBM 1620 Data Processing System
This is not the 1620 in Watson Lab.
The 1620 was relatively small and inexpensive for its day.
A variation of the 1620 was the 1710, which had analog/digital converters, interrupts, and other features needed for industrial process control.

 Definition of IBM 1620
Most of the logic circuitry of the 1620 was a type of resistor-transistor logic (RTL) using "drift" transistors (a type of transistor invented by Herbert Kroemer in 1957) for their speed, that IBM referred to as SDTRL.
Following announcement of the IBM 1620 on October 22, 1959, due to an internal reorganization of IBM, it was decided to transfer the computer from the Data Processing Division at Poughkeepsie (large scale mainframe computers only) to the General Products Division at San Jose (small computers and support products only) for manufacturing.
Work was begun on a 1620 Model III in year-TBD, but the project was quickly canceled as IBM wanted to promote sales of their new System/360 and discontinue the old lines.

 IBM Archives: 1620 Data Processing System
The IBM 1620 was a general-purpose, stored-program data processing system for small businesses, research and engineering departments of large companies, and schools requiring solutions to complex problems in the areas of engineering, research, and management science.
With the 1711 model 2 and 1712 Multiplexer and Terminal Unit connected to the 1620, the computer not only received data from analog measuring devices, but fed results through the 1711/1712 to control processes by closing contacts which completed circuits to the instrumentation for closed-loop process control.
1620 symbolic language allowed the programmer to refer to instructions and data in the program by name or other meaningful designation without regard to their location in the machine to facilitate relocating sections of programs, incorporating subroutines, and inserting or deleting instructions.

The 1620 cost from around $85,000(?) up to hundreds of thousands of dollars(?) according to the configuration.
Because the 1620 was popular with colleges, IBM ran a clearing house of software for a nominal cost such as Snobol, COBOL, chess games, etc.
1620 consoles were used as props to represent Colossus in the film "The Forbin Project", though most of the machines had been scrapped by the time the film was made.

 Mackie - Onyx 1620
Get a Mackie Onyx 1620 Mixer Bag to go along with your Onyx 1620.
We rounded out the Onyx 1620 feature set by answering some common requests from our compact mixer customers: adding individual 48v phantom power and balanced direct outputs on every channel; a full Auxiliary section with Pre/Post control; and a new Talkback section with a convenient built-in mic.
In the category of "Why didn't someone think of this sooner?", we gave the Onyx 1620 an optional FireWire I/O card, which bridges the analog-to-digital gap by providing up to 18 independent channels of high-quality 24-bit/96kHz audio that you can plug right into your FireWire-equipped Mac or PC.

Monatrope 1620 is an alkyl polysaccharide with a range of properties required in an increasing number of cleaning formulations.
Monatrope 1620 is resistant to attack by strong alkalis, hence has excellent long term stability in strongly alkaline solutions that are typical of some of the higher performing cleaning formulations being brought to market today.
The 48-hour EC50 to the freshwater invertebrate Daphnia magna was found to be greater than 100 mg/liter and the assessment of toxicity to Pseudomonas putida, performed to characterize the potential for adverse effects on biological treatment, revealed a similar order of toxicity with an LC 50 greater than 560 mg/liter.

The IBM 1620 I was the original implementation of the IBM 1620, introduced in 1959.
This unit (commonly called 1620 until the Model II was introduced) was produced as inexpensively as IBM could make it, in order to keep the price low.

 PlYMOUTH MA - ITS HISTORY AND PEOPLE
The pilgrims founded Plymouth on Dec. 21, 1620, establishing a settlement that became the seat of Plymouth Colony in 1633 and a part of Massachusetts Bay Colony in 1691.
The term Pilgrim is derived from his description of himself and his coreligionists as they left Holland (July 22, 1620) for Southampton, where they joined another group of English separatists on the Mayflower.
His influence was instrumental in winning the approval of the Virginia Company for the proposal to resettle the congregation in America, and he was one of the few original Scrooby separatists who sailed on the Mayflower in 1620.

It is considered to be much harder to make a global change in host software than to change router software, because there are many more hosts and host vendors than routers and router vendors, and because hosts are less centrally administered than routers.
In order for the hop-by-hop redirection mechanism to eliminate all router hops, allowing two hosts connected to the same SM to communicate directly, a [X]Redirect message must be able to carry the IP address of the destination host.
The router could use the attribute "SameSM" for a route to deduce the shortest path to be reported to its neighbors.

The goal for the Onyx 1620 was no short order: to create a small-format analog mixer with more useful features, better sound quality, advanced tonal shaping, and full FireWire connectivity options.
The Onyx 1620 starts with eight of Mackie's Onyx mic preamps, which meet or surpass just about any standalone mic preamp on the market in terms of pure fidelity and headroom (and yes, there are specs to prove it).
Next up is the completely new Perkins EQ circuitry, a "neo-classic" 4-band design that gives you the sweet musicality of British EQ with greater filter control and minimum phase shift (plus a true hardware EQ bypass).
