Slot 1 refers to the physical and electrical specification for the connector used by some of Intel's microprocessors, including the Pentium Pro, Celeron, Pentium II and the Pentium III. Both single and dual processor configurations were implemented.

Intel switched back to the traditional socket interface with Socket 370 in 1999.

General[edit]

With the introduction of the Pentium II CPU, the need for greater access for testing had made the transition from socket to slot necessary. Previously with the Pentium Pro, Intel had combined processor and cache dies in the same Socket 8 package. These were connected by a full-speed bus, resulting in significant performance benefits. Unfortunately, this method required that the two components be bonded together early in the production process, before testing was possible. As a result, a single, tiny flaw in either die made it necessary to discard the entire assembly, causing low production yield and high cost.[citation needed]

Aristocrat Slots Online manufactured this entertaining new theme with Wilds, Free Spins, Multipliers, scatters, Michonne Attack, Reel Growth, Wild Attack, and a cool bonus round that Walking Dead fans are going to love. All this is set over a massive 100 pay-lines with a potential £500,000 pay-out.

Intel subsequently designed a circuit board where the CPU and cache remained closely integrated, but were mounted on a printed circuit board, called a Single-Edged Contact Cartridge (SECC). The CPU and cache could be tested separately, before final assembly into a package, reducing cost and making the CPU more attractive to markets other than that of high-end servers. These cards could also be easily plugged into a Slot 1, thereby eliminating the chance for pins of a typical CPU to be bent or broken when installing in a socket.

The form factor used for Slot 1 was a 5-inch-long, 242-contact edge connector named SC242. To prevent the cartridge from being inserted the wrong way, the slot was keyed to allow installation in only one direction. The SC242 was later used for AMD's Slot A as well, and while the two slots were identical mechanically, they were electrically incompatible. To discourage Slot A users from trying to install a Slot 1 CPU, the connector was rotated 180 degrees on Slot A motherboards.

With the new Slot 1, Intel added support for symmetric multiprocessing (SMP). A maximum of two Pentium II or Pentium III CPUs can be used in a dual slot motherboard. The Celeron does not have official SMP support.

There are also converter cards, known as Slotkets, which hold a Socket 8 so that a Pentium Pro CPU can be used with Slot 1 motherboards.[2] These specific converters, however, are rare. Another kind of slotket allows using a Socket 370 CPU in a Slot 1. Many of these latter devices are equipped with own voltage regulator modules, in order to supply the new CPU with a lower core voltage, which the motherboard would not otherwise allow.

Form factors[edit]

The Single Edge Contact Cartridge, or 'SECC', was used at the beginning of the Slot 1-era for Pentium II CPUs. Inside the cartridge, the CPU itself is enclosed in a hybrid plastic and metal case. The back of the housing is plastic and has several markings on it: the name, 'Pentium II'; the Intel logo; a hologram; and the model number. The front consists of a black anodized aluminum plate, which is used to hold the CPU cooler. The SECC form is very solid, because the CPU itself is resting safely inside the case. As compared to socket-based CPUs, there are no pins that can be bent, and the CPU is less likely to be damaged by improper installation of a cooler.

Following SECC, the SEPP-form (Single Edge Processor Package) appeared on the market. It was designed for lower-priced Celeron CPUs. This form lacks a case entirely, consisting solely of the printed-circuit board holding the components.

A form factor called SECC2 was used for late Pentium II and Pentium III CPUs for Slot 1, which was created to accommodate the switch to flip chip packaging.[3] Only the front plate was carried over, the coolers were now mounted straight to the PCB and exposed CPU die and are, as such, incompatible with SECC cartridges.

History[edit]

Historically, there are three platforms for the Intel P6-CPUs: Socket 8, Slot 1 and Socket 370.

Slot 1 is a successor to Socket 8. While the Socket 8 CPUs (Pentium Pro) directly had the L2-cache embedded into the CPU, it is located (outside of the core) on a circuit board shared with the core itself. The exception is later Slot 1 CPUs with the Coppermine core which have the L2-Cache embedded into the die.

In the beginning of 2000, while the Pentium-III-CPUs with FC-PGA-housing appeared, Slot 1 was slowly succeeded by Socket 370, after Intel had already offered Socket 370 and Slot 1 at the same time since the beginning of 1999. Socket 370 was initially made for the low-cost Celeron processors, while Slot 1 was thought of as a platform for the expensive Pentium II and early Pentium III models. Cache and core were both embedded into the die.

Slot 1 also obsoleted the old Socket 7, at least regarding Intel, as the standard platform for the home-user. After superseding the Intel P5Pentium MMX CPU, Intel completely left the Socket 7 market.

Book of Dead Slot Review

The first thing we need to mention is its actual name: Rich Wilde and the Book of Dead. However, we will refer it simply as Book of Dead from now on – it is much more practical.

Book of Dead is a classic video slot machine released in January 2016, and since then, it is one of the most popular games of Play'n GO. It is played on a 5×3 grid and contains 5 reels & 10 paylines. And it is also a no downloads slot, which means you can play it on our website without a download and registration. You can also pick one of our recommended online casinos if you want to try your chance with real money. However, before doing any of these, make sure to read our review. It contains everything you need to know about the Book of Dead slot.

How to Play Book of Dead Slot Machine

If you want to learn to play slots online, free, you can start with the Book of Dead. It is easy to learn and play. Here is what you need to do, step-by-step:

  • The goal is landing at least 2 same symbols side by side on a payline. (Note that some symbols pay only after landing 3.) When you do that, you will be qualified for a payout according to the paytable. (Check the paytable below for more information.) Your payout will be determined according to which and how many symbols you landed.
  • Before starting to play, we need to do two things. First, we should check the paytable by clicking the same-named button at the bottom right corner. Doing so will open a secondary screen where we can see the rules, symbols, and payouts. Read all of them at least once. Second, we need to determine our bet amount per spin. No worries: Book of Dead belongs to the free online penny slots category, which means it does not cost that much to play (if you are playing the real money version, of course).
  • To do this, we will use three buttons. The one that says 'coin value' sets the value of a single coin. The minimum value is 0.01 – this means if we play this game with 1 coin, it will be worth 0.01 credits. However, this is just for a single payline. Since there are 10 paylines, we need to multiply this value with 10 to see the actual cost per spin: 0.10 credits (0.01 x 10). In other words, the minimum cost per spin is 0.10 credits when we play the game with a single coin & 10 paylines.
  • The maximum coin value is 1.00. The math is the same: We multiply this with 10 to see the actual maximum cost per spin = 10 credits. When we play the game with a single coin and 10 paylines, the cost of each spin will cost 10 credits.
  • We are saying 'if we play the game with a single coin' because this can be changed from the section that says 'coins'. If you wish, you can bet up to 5 coins per spin. Likewise, you can also change the number of paylines. In this case, the minimum and maximum costs will also change. There is no real reason to do these. Stick with a single coin per spin and 10 paylines.
  • After determining the bet amount per spin, we can start playing the game. Click the 'spin' button to start playing the game. The 'autoplay' button will spin the reels automatically. You will keep spinning the reels until you win a prize or activate a bonus feature.

Book of Dead Slot Game Symbols & Payouts

Book of Deads free slot machine contains 9 symbols in total. Four of these symbols are shown with theme-related pictures. These are high-value symbols, and it is enough to land 2 of them on a payline to get paid. The remaining symbols are shown with play card signs. They pay less, and you must land at least 3 of them on a payline to get paid. The paytable is fixed and does not change according to your bet amount. The only exception is the scatter payout, which we will explain below.

Book of Dead also has a special symbol, which is shown with a picture of a spellbook. This symbol is wild and scatter at the same time. This means:

  • It is used to trigger the bonus free spins feature,
  • It substitutes any other symbol to complete a winning combination,
  • It makes a payout no matter where it lands on the reels (landing on a payline is not necessary).

The thing about the scatter symbol is, its payout will be multiplied by the total bet amount and added to the payline win. And since there is no need to land it on a payline, this may result in quite high payouts. Speaking of which, the highest payout of Book of Dead slot is 250.000 coins.

Let's continue with the paytable that shows the symbol payout values. After that, we will explain the bonus feature.

Bonus Features of Free Book of Dead Slot

There are two bonus features in the Book of Dead slot machine, and the first one is the free spins round. Landing at least three scatter symbols anywhere on the reels will award 10 free spins. However, before the round starts, a random symbol will be chosen by the game. This symbol will gain the 'expanding' feature. This means if it lands on a reel during the free spins round, it can expand and cover the entire reel. As can be guessed, this increases your winning chance.

The second bonus feature is the gamble round. It becomes active automatically after every winning spin. You can choose to play it or not – it is up to you. If you choose to play, you will be asked to guess the colour or the suit of a closed play card. Guessing the colour right pays 2x, and guessing the suit right pays 4x. You can play this game until you win 2.500 coins in total. If you lose, you will lose your initial payout too.

How to Win Book of Dead Free Slots: Tips & Tricks

There is no sure way of winning the game: The results of a spin are determined by an RNG (random number generator) software, and nobody can predict the results. However, we can give you a couple of tips in order to increase your winning chances:

  • Play with a single coin, 10 paylines, and minimum bet amount. There are multiplier payouts in Book of Dead, but only the scatter symbol offers them. While scatter payouts sound nice, they increase the total cost of spinning the reels too much. The best price/performance ratio can be achieved by playing the game with a single coin, 10 paylines, and minimum bet amount.
  • Do not play a gambling game. Doubling or quadrupling your payout sounds like a nice idea, but if you lose, you will lose your original payout too. And don't forget that your chance of losing is 50%: This is a high figure, and you should not take this risk.
