* Overview of Device Interrupt Support
*
* Originally, the CPU maintained a queue of requested interrupts. Entries in this queue recorded a device's
* priority, vector, and delay (ie, a number of instructions to execute before dispatching the interrupt). This
* queue would constantly grow and shrink as requests were issued and dispatched, and as long as there was something
* in the queue, the CPU was constantly examining it.
*
* Now we are trying something more efficient. First, for devices that require delays (like the SerialPort's receiver
* and transmitter buffer registers, which are supposed to "clock" the data in and out at a specific baud rate), the
* CPU offers timer services that will "fire" a callback after a specified delay, which are much more efficient than
* requiring the CPU to dive into an interrupt queue and decrement delay counts on every instruction.
*
* Second, devices that generate interrupts will allocate an IRQ object during initialization; we will no longer
* be creating and destroying interrupt event objects and inserting/deleting them in a constantly changing queue.
* Each IRQ contains properties that never change (eg, the vector and priority), along with a "next" pointer that's
* only used when the IRQ is active.
*
* When a device decides it's time to interrupt (either at the end of some I/O operation or when a timer has fired),
* it will simply set the IRQ, which basically means that the IRQ will be linked onto a list of active IRQs, in
* priority order, so that when the CPU is ready to acknowledge interrupts, it need only check the top of the active
* IRQ list.

From the "PDP-10 System Reference Manual", May 1968, p. 1-4:
1.1 NUMBER SYSTEM
The program can interpret a data word as a 36-digit, unsigned binary number, or the left and right
halves of a word can be taken as separate 18-bit numbers. The PDP-10 repertoire includes instructions
that effectively add or subtract one from both halves of a word, so the right half can be used for
address modification when the word is addressed as an index register, while the left half is used to
keep a control count.
The standard arithmetic instructions in the PDP-10 use twos complement, fixed point conventions to do
binary arithmetic. In a word used as a number, bit 0 (the leftmost bit) represents the sign, 0 for positive,
1 for negative. In a positive number the remaining 35 bits are the magnitude in ordinary binary notation.
The negative of a number is obtained by taking its twos complement. If x is an n-digit binary number, its
twos complement is 2^n - x, and its ones complement is (2^n - 1) - x, or equivalently (2^n - x) - 1.
Subtracting a number from 2^n - 1 (ie, from all 1s) is equivalent to performing the logical complement,
ie changing all 0s to 1s and all 1s to 0s. Therefore, to form the twos complement one takes the logical
complement (usually referred to merely as the complement) of the entire word including the sign, and adds
1 to the result. In a negative number the sign bit is 1, and the remaining bits are the twos complement
of the magnitude.
Zero is represented by a word containing all 0s. Complementing this number produces all 1s, and adding
1 to that produces all 0s again. Hence there is only one zero representation and its sign is positive.
Since the numbers are symmetrical in magnitude about a single zero representation, all even numbers both
positive and negative end in 0, all odd numbers in 1 (a number all 1s represents -1). But since there are
the same number of positive and negative numbers and zero is positive, there is one more negative number
than there are nonzero positive numbers. This is the most negative number and it cannot be produced by
negating any positive number (its octal representation is 400000 000000 and its magnitude is one greater
than the largest positive number).
If ones complements were used for negatives one could read a negative number by attaching significance
to the as instead of the 1s. In twos complement notation each negative number is one greater than the
complement of the positive number of the same magnitude, so one can read a negative number by attaching
significance to the rightmost 1 and attaching significance to the 0s at the left of it (the negative number
of largest magnitude has a 1 in only the sign position). In a negative integer, 1s may be discarded at the
left, just as leading 0s may be dropped in a positive integer. In a negative fraction, 0s may be discarded
at the right. So long as only 0s are discarded, the number remains in twos complement form because it
still has a 1 that possesses significance; but if a portion including the rightmost 1 is discarded, the
remaining part of the fraction is now a ones complement.
The computer does not keep track of a binary point - the programmer must adopt a point convention and shift
the magnitude of the result to conform to the convention used. Two common conventions are to regard a number
as an integer (binary point at the right) or as a proper fraction (binary point at the left); in these two
cases the range of numbers represented by a single word is -2^35 to 2^35 - 1, or -1 to 1 - 2^35. Since
multiplication and division make use of double length numbers, there are special instructions for performing
these operations with integral operands.
SIDEBAR: Multiplication produces a double length product, and the programmer must remember that discarding
the low order part of a double length negative leaves the high order part in correct twos complement form
only if the low order part is null.
...
2.5 FIXED POINT ARITHMETIC
For fixed point arithmetic the PDP-10 has instructions for arithmetic shifting (which is essentially
multiplication by a power of 2) as well as for performing addition, subtraction, multiplication and division
of numbers in fixed point format [§ 1.1]. In such numbers the position of the binary point is arbitrary
(the programmer may adopt any point convention). The add and subtract instructions involve only single length
numbers, whereas multiply supplies a double length product, and divide uses a double length dividend. The high
and low order words respectively of a double length fixed point number are in accumulators A and A+1 (mod 20),
where the magnitude is the 70-bit string in bits 1-35 of the two words and the signs of the two are identical.
There are also integer multiply and divide instructions that involve only single length numbers and are
especially suited for handling smaller integers, particularly those of eighteen bits or less such as addresses
(of course they can be used for small fractions as well provided the programmer keeps track of the binary point).
For convenience in the following, all operands are assumed to be integers (binary point at the right).
The processor has four flags, Overflow, Carry 0, Carry 1 and No Divide, that indicate when the magnitude of a
number is or would be larger than can be accommodated. Carry 0 and Carry 1 actually detect carries out of bits
0 and 1 in certain instructions that employ fixed point arithmetic operations: the add and subtract instructions
treated here, the move instructions that produce the negative or magnitude of the word moved [§ 2.2], and the
arithmetic test instructions that increment or decrement the test word [§ 2.7]. In these instructions an
incorrect result is indicated - and the Overflow flag set - if the carries are different, ie if there is a carry
into the sign but not out of it, or vice versa. The Overflow flag is also set by No Divide being set, which
means the processor has failed to perform a division because the magnitude of the dividend is greater than or
equal to that of the divisor, or in integer divide, simply that the divisor is zero. In other overflow cases
only Overflow itself is set: these include too large a product in multiplication, and loss of significant bits
in left arithmetic shifting.
SIDEBAR: Overflow is determined directly from the carries, not from the carry flags, as their states may reflect
events in previous instructions.

* The 'value' property stores the 36-bit value as an unsigned integer. When the value should be

*
* The 'remainder' property stores the remainder from the last division. You should assume it will

*
* The 'error' property records any error(s) from the last operation.
*
* NOTE: What we call extended Int36 values DEC refers to as "double length numbers", and they refer

* presumably because they number the left-most significant bit 0.
*/
class Int36 {
/**
* Int36(obj, extended)
*
* The constructor, which simply calls set(), creates an Int36 from either:
*
* 1) another Int36
* 2) a single 36-bit value, with an optional 36-bit extension
* 3) nothing (initial value will be zero)
*
* All internal Int36 values (ie, the value and any extension) are unsigned values in the range:
*
* 0 <= i <= Math.pow(2, 36) - 1
*
* The lower bound is ZERO and the upper bound is Int36.MAXVAL. Whenever an Int36 value should be
* interpreted as a signed value, values above Int36.MAXPOS (ie, values with bit 35 set) should be
* converted to their signed counterpart by subtracting the value from Int36.BIT36 (aka MAXVAL + 1);
* the easiest way to do that is call isNegative() to check the sign bit and then call negate() as
* appropriate.
*
* NOTE: We use modern bit numbering, where bit 0 is the right-most (least-significant) bit and
* bit 35 is the left-most bit. This is opposite of the PDP-10 convention, which defined bit 0 as the
* left-most bit and bit 35 as the right-most bit.
*
* Although the integer precision of JavaScript floating-point (IEEE 754 double-precision) numbers is:
*
* -Math.pow(2, 53) <= i <= Math.pow(2, 53)
*
* it seems unwise to ever permit our internal values to creep outside the 36-bit range, because
* floating-point operations will drop least-significant bits in favor of most-significant bits when a
* result becomes too large, which is the opposite of what integer operations traditionally do. There
* might be some optimization benefits to performing our internal 36-bit truncation "lazily", but at
* least initially, I prefer to truncate() the results of all 36-bit arithmetic operations immediately.
*
* Most of the Int36 operations come in two flavors: those that accept numbers, and those that accept
* another Int36. The latter are more efficient, because (as just explained) an Int36's internal value
* should always be in range, whereas external numbers could be out of range OR have a fractional value
* OR be something else entirely (NaN, Infinity, -Infinity, undefined, etc), so numeric inputs are
* always passed through the static validate() function.
*
* We could eliminate the two flavors and check each parameter's type, like we do in the constructor,
* but constructor calls are infrequent (if they're not, you're doing something wrong), whereas Int36-only
* operations should be as fast and unchecked as possible.
