	Woodford County Almshouse Registers Index (1868-1957)
		The Woodford County Almshouse Registers Index was compiled by Eric Groenke, intern for the Illinois Regional Archives Depository (IRAD) System at Illinois State University in Normal.
		Each entry found in the index contains the following categories of information: the name, birthplace, age and occupation of the inmate; the date of admission to the almshouse; and the page and volume numbers.
		Registers show the admission number; the name, birthplace, occupation, age and former residence of the inmate; the dates of admission and discharge; the date of death (when the inmate died while staying at the almshouse); and remarks.

	Index register - Wikipedia, the free encyclopedia
		An index register in a computer's CPU is a processor register used for modifying operand addresses during the run of a program, typically for doing vector/array operations.
		Index registers were first used in the British Manchester Mark I computer, in 1949.
		Before the invention of index registers, and without indirect addressing, array operations had to be performed either by linearly repeating program code for each array element (i.e.

	Index Registers and Loops
		Index registers on the 7090/94 were 15-bits in length (enough to span 32,768 words) and were used primarily for loop counters and to modify addresses.
		Index registers had four specific associated instruction types: Load an index register; store the contents of an index register; increase or decrease the contents of an index register; and test the contents of an index register.
		The contents of the index register could be added to the address field to form the final address by specifying the 2's-complement of the quantity in the source code which would also be subtracted to yield the same affect as adding (almost all of the remainder of the 7090/94 architecture was 1's-complement based).

	Method and means to access and extended memory unit - Patent 3976976
		When an instruction calls for indexing, the operand is modified by the specified index register as normal, the extended bits of that index register is appended to the resultant operand to form an extended effective address.
		The output of the B register is fed to R' register (15 bits) which holds the quantity while it is added to the output of the lower-order 15 bits, UL, during address modification.
		The output of the BX register (3 bits) is fed to holding register R'X, the output of which is fed to the SX portion (3 bits) of register 44.

		The three bits of the tag specified three (seven in the 7094) index registers, the contents of which were subtracted from the address to produce an effective address.
		The Index registers operated using two's complement format and when used to modify an instruction address were subtracted from the address in the instruction.
		The IBM 7094, with seven index registers had a "compatibility" mode to permit programs from earlier machines that used this trick to continue to be used.

	Registers
		Registers are fast memory, almost always connected to circuitry that allows various arithmetic, logical, control, and other manipulations, as well as possibly setting internal flags.
		In some RISC processors, constant registers are used to store commonly used values (such as zero, one, or negative one) — for example, a constant register containing zero can be used in register to register data moves, providing the equivalent of a clear instruction without adding one to the instruction set.
		Index registers are used to provide more flexibility in addressing modes, allowing the programmer to create a memory address by combining the contents of an address register with the contents of an index register (with displacements, increments, decrements, and other options).

	Closed-loop reading of index registers using wide read and narrow write for multi-threaded system (US6188411)
		When index registers are read in a multi-threaded system, programs in two different threads could access the same index register, each writing a different index into the index register.
		The current thread detects that the index was overwritten by another thread by extracting the index from the 16-bit read and comparing it to the desired index.
		whereby the stored index is read with the selected data from the selected data register that is selected by the stored index to determine when to re-execute reading the indexed registers.

	Index Registers and Addressing
		You put a pointer to it in the index register, and use an offset to the field you want in the offset field.
		index register also gives us an opportunity to learn about a standard hack that manufacturers apply to their instruction sets to expand them beyond the limitations of their original design: a prefix byte.
		When they wanted to add a second index register, they had a problem: their were too many instructions using indexed addressing to just add that many new op codes to the instruction set.

	Registers and Indexed Registers
		A register is just a memory location, and can be accessed using the appropriate CPU instructions for the address space in which it lives.
		For this reason, operations on index registers are often performed "atomically," or a lock is used to tell other threads or processes to keep their hands off the "index register" while you are using it.
		In some, unfortunately not so rare, cases, the "index register" and "data register" are at the same location, and the location alternates between being the "index register" and being the "data register" with each access, often with a separate register to reset the first to index mode.

		This extra facility offered by the index registers can be quite powerful, but is only likely to be used by the more experienced machine code programmer, so we'll deal with it in theory only.
		Indexed addressing with the Z80 CPU is not as powerful as with other processors, such as the 6502, so if you don't want to use them, it is usually relatively easy to just use the other registers instead.
		In this case it means that the register 'C' holds the identifying value of the port.

		After the D register is added to the 8-bit offset, the appropriate register is added, and the effective address is normalized to fall within bank 0.
		When the index registers are changed from 16 bit to 8 bit, the high byte of each index register is lost and forced to zero.
		However, unlike the index registers, MVN and MVP treats the Accumulator as 16 bits wide, regardless of the state of the M flag.

		This leaves the index registers and accumulator/memory into 8 bit mode (which is the same as emulation mode).
		While the status register is set for 16 bit memory/accumulator mode (m=0), data loaded is 16 bits wide with the load byte coming from the effective address and the high byte of the accumulator coming from the effective address plus one.
		When the status register is set to 16 bit index register mode (x=0), the pull and push index registers will operate on 16 bits when the status register x is set to 0.

		Spills and fills occur only at the ends of the cache, and registers are saved/loaded from the memory stack (normally implemented as a register cache separate from the execution stack, similar to the way FORTH uses stacks).
		The 80C166 has sixteen 16 bit registers, with the lower eight usable as sixteen 8 bit registers, which are stored in overlapping windows (like in the SPARC) in the on-chip RAM (or register bank), pointed to by the Context Pointer (CP) (similar to the SP in the AMD 29K).
		Unlike the SPARC, register windows can overlap by a variable amount (controlled by the CP), and the there are no spills or fills because the registers are considered part of the RAM address space (like in the TMS 9900), and could even extend to off chip RAM.

		By the 1900s earlier mechanical calculators, cash registers, accounting machines, and so on were redesigned to use electric motors, with gear position as the representation for the state of a variable.
		All machines at that date still lacked what became known as the von Neumann architecture: their programs were not stored in the same memory 'space' as the data and hence programs could not be manipulated as data.
		The first working von Neumann machine was the Manchester "Baby" or Small-Scale Experimental Machine, built at the University of Manchester in 1948; it was followed in 1949 by the Manchester Mark I computer which functioned as a complete system using the Williams tube for memory, and also introduced index registers.
