16-bit application (foldoc) | 16-bit application
 
     Software for MS-DOS or {Microsoft
    Windows} which originally ran on the 16-bit Intel 8088 and
    80286 microprocessors.  These used a {segmented address
    space} to extend the range of addresses from what is possible
    with just a 16-bit address.  Programs with more than 64
    kilobytes of code or data therefore had to waste time
    switching between segments.  Furthermore, programming with
    segments is more involved than programming in a {flat address
    space}, giving rise to warts like memory models in C and
    C++.

192.168.1.1 (foldoc) | 192.168.1.1
 
     The default IP address used to connect to many
    brands of router to set them up.  It can be used from a {web
    browser} in the URL (http://192.168.1.1).  This URL, and
    the necessary default login details, are often printed on the
    router.  The same address may also be accessible via a
    telnet command line interface.
 
    This is a private address that is only visible when
    connected directly to the router, i.e. it will not be routed
    by other network hardware.

ibm 1620 (foldoc) | IBM 1620
 
     A computer built by IBM and released in late
    1959.  The 1620 cost from around $85,000(?) up to hundreds of
    thousands of dollars(?) according to the configuration.  It
    was billed as a "small scientific computer" to distinguish it
    from the business-oriented IBM 1401.  It was regarded as
    inexpensive, and many schools started out with one.
 
    It was either developed for the US Navy to teach computing, or
    as a replacement for the very successful IBM 650 which did
    quite well in the low end scientific market.  Rumour has it
    that the Navy called this computer the CADET - Can't Add,
    Doesn't Even Try.
 
    The ALU used lookup tables to add, subtract and multiply but
    it could do address increments and the like without the
    tables.  You could change the number base by adjusting the
    tables, which were input during the boot sequence from
    Hollerith cards.  The divide instruction required additional
    hardware, as did floating point operations.
 
    The basic machine had 20,000 decimal digits of {ferrite core
    memory} arranged as a 100 by 100 array of 12-bit locations,
    each holding two digits.  Each digit was stored as four
    numeric bits, one flag bit and one parity bit.  The numeric
    bits stored a decimal digit (values above nine were illegal).
 
    Memory was logically divided into fields.  On the high-order
    digit of a field the flag bit indicated the end of the field.
    On the low-order digit it indicated a negative number.  A flag
    bit on the low order of the address indicated {indirect
    addressing} if you had that option installed.  A few "illegal"
    bit combinations were used to store things like record marks
    and "numeric blanks".
 
    On a subroutine call it stored the return address in the
    five digits just before the entry point to the routine, so you
    had to build your own stack to do recursion.
 
    The enclosure was grey, and the core was about four or five
    inches across.  The core memory was kept cool inside a
    temperature-controlled box.  The machine took a few minutes to
    warm up after power on before you could use it.  If it got too
    hot there was a thermal cut-out switch that would shut it
    down.
 
    Memory could be expanded up to 100,000 digits in a second
    cabinet.  The cheapest package used paper tape for I/O.  You
    could also get punched cards and later models could be
    hooked up to a 1311 disk drive (a two-megabyte {washing
    machine}), a 1627 plotter, and a 1443 line printer.
 
    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.
 
    The model II, released about three years later, could add and
    subtract without tables.  The clock period decreased from 20
    to 10 microseconds, instruction fetch sped up by a few cycles
    and it added index registers of some sort.  Some of the
    model I's options were standard on the model II, like
    indirect addressing and the console teletype changed
    from a model C to a Selectric.  Later still, IBM marketed
    the IBM 1710.
 
    A favorite use was to tune a FM radio to pick up the
    "interference" from the lights on the console.  With the right
    delay loops you could generate musical notes.  Hackers wrote
    interpreters that played music from notation like "C44".

    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.

iso 3166 (foldoc) | country code
 ISO 3166
 
     Originally, a two-letter abbreviation
    for a particular country (or geographical region), generally
    used as a top-level domain.
 
    Originally country codes were just for countries; but country
    codes have been allocated for many areas (mostly islands) that
    aren't countries, such as Antarctica (aq), Christmas Island
    (cx) and Saint Pierre et Miquelon (pm).
 
    Country codes are defined in ISO 3166 and are used as the
    top level domain for Internet hostnames in most countries
    but hardly ever in the USA (code "us").  ISO 3166 defines
    short and full english and french names, two- and three-letter
    codes and a three-digit code for each country.
 
    There are also language codes.

mcp-1600 (foldoc) | MCP-1600
 
    A processor made by Western Digital, consisting of at least
    four separate integrated circuits, including the control
    circuitry unit, the ALU, two or four ROM chips with
    microcode, and timing circuitry.
 
    The ALU chip contained twenty-six 8-bit registers and an
    8-bit ALU, while the control unit supervised the moving of
    data, memory access, and other control functions.  The ROM
    allowed the chip to function as either an 8- or 16-bit chip,
    with clever use of the 8-bit ALU.  Further, microcode
    allowed the addition of floating-point routines (40 + 8 bit
    format), simplifying programming (and possibly producing a
    floating-point coprocessor).
 
    Two standard microcode ROMs were available.  This
    flexibility was one reason it was also used to implement the
    DEC LSI-11 processor as well as the WD {Pascal
    Microengine}.
