just adding a CPU a stick of RAM a storage device and a power supply to a

4
00:00:12,480 --> 00:00:20,220
mini ITX motherboard will give you a small and fully functional computer in a

5
00:00:17,910 --> 00:00:24,810
matter of minutes and this is possible because of how many different functions

6
00:00:22,230 --> 00:00:30,480
the average motherboard combines into one little slab of like fiberglass metal

7
00:00:28,170 --> 00:00:35,700
and silicon but it wasn't always like this in fact early electronics didn't

8
00:00:33,239 --> 00:00:40,440
have anything resembling the lovely green boards with black integrated

9
00:00:37,890 --> 00:00:45,030
circuits that were used to today instead it was common to see individual full

10
00:00:42,719 --> 00:00:50,270
sized wires linking every capacitor resistor and other component necessary

11
00:00:47,910 --> 00:00:55,590
to make up a full computer system unsurprisingly this approach took up

12
00:00:52,920 --> 00:01:01,590
tons of space added a bunch of weight and was relatively fragile meaning that

13
00:00:59,190 --> 00:01:06,299
the printed circuit board took off in popularity pretty quickly starting in

14
00:01:03,660 --> 00:01:12,390
the 1950s it should be noted however that these early PCBs were still a far

15
00:01:09,659 --> 00:01:16,710
cry from the RGB motherboard that you might have sitting in your computer

16
00:01:13,740 --> 00:01:21,650
right now while back then a simple device like a radio might have gotten

17
00:01:19,110 --> 00:01:26,189
away with using just one PCB full-fledged computers needed many

18
00:01:24,360 --> 00:01:31,439
circuit boards to handle different functions connected by a backplane that

19
00:01:29,189 --> 00:01:35,939
you might consider to be a forerunner of the modern motherboard unlike true

20
00:01:34,110 --> 00:01:41,130
motherboards though these back planes tended to be dumb connections with no

21
00:01:38,610 --> 00:01:46,079
actual logic that consisted of little more than a bunch of slots lined up in a

22
00:01:43,530 --> 00:01:52,110
row so that other expansion cards could be plugged in for example the Altair

23
00:01:48,750 --> 00:01:55,710
8800 used one slot to insert a processor

24
00:01:52,110 --> 00:01:59,520
another for memory and so on it wasn't

25
00:01:55,710 --> 00:02:02,130
until 1981 that we got a big upgrade the

26
00:01:59,520 --> 00:02:10,170
planar board in the original IBM PC featured an Intel 8088 CPU built in

27
00:02:06,210 --> 00:02:13,319
memory and actual external IO so it was

28
00:02:10,170 --> 00:02:16,420
far more than just a glorified bundle of

29
00:02:13,319 --> 00:02:18,250
wire like smooshed together all you

30
00:02:16,420 --> 00:02:23,140
could connect directly to it was a keyboard and a cassette drive but it

31
00:02:21,070 --> 00:02:27,040
also included a handful of expansion slots that didn't look too different

32
00:02:25,000 --> 00:02:31,030
from what we're used to today and those slots were important because

33
00:02:28,300 --> 00:02:36,280
motherboards were still so simple that they didn't have features that we

34
00:02:32,890 --> 00:02:38,620
consider basic now like drive headers

35
00:02:36,280 --> 00:02:44,380
for example so if you wanted to load up your copy of flight simulator 1.0 you

36
00:02:41,560 --> 00:02:49,900
would need a standalone disk interface card and we didn't see modern memory

37
00:02:47,020 --> 00:02:55,270
modules that fit into RAM slots until the mid-1980s either by the late 80s

38
00:02:53,110 --> 00:02:59,920
though engineers had fully embraced the goal of integrating more and more

39
00:02:57,730 --> 00:03:06,010
functions onto the motherboard and so little ICS called super i/o chips were

40
00:03:03,430 --> 00:03:10,810
becoming more common these functioned like rudimentary versions of a modern

41
00:03:08,170 --> 00:03:17,350
chipset they provided drive controllers ports for printers mice keyboards and

42
00:03:13,480 --> 00:03:19,630
other devices and the systems BIOS now

43
00:03:17,350 --> 00:03:25,000
that all doesn't sound like a huge deal today but super i/o chips took up less

44
00:03:22,299 --> 00:03:29,530
space and they were much more cost effective than expansion cards setting

45
00:03:27,340 --> 00:03:34,630
the stage for full-featured modern motherboards around the same time in

46
00:03:32,019 --> 00:03:41,440
1987 specifically we've got the first ever integrated VGA graphics chips when

47
00:03:38,140 --> 00:03:44,769
IBM released model 50 of their almost

48
00:03:41,440 --> 00:03:47,320
famous personal system - unlike modern

49
00:03:44,769 --> 00:03:51,040
integrated GPUs though this was a chip that was affixed to the motherboard

50
00:03:49,209 --> 00:03:57,549
instead of being built into the CPU itself a paradigm that we saw again

51
00:03:53,950 --> 00:04:00,880
starting in the mid-1990s as 3d GPUs

52
00:03:57,549 --> 00:04:03,220
like the s3 trio and the ati rage series

53
00:04:00,880 --> 00:04:08,470
appeared on motherboards obviating the need for a separate card for basic use

54
00:04:05,739 --> 00:04:13,840
though GPUs that were soldered onto motherboards began to disappear in favor

55
00:04:10,780 --> 00:04:16,450
of ones built into CPUs by the mid 2010

56
00:04:13,840 --> 00:04:23,229
speaking of CPUs let's jump back again to 1989 when the first CPU socket with a

57
00:04:20,320 --> 00:04:27,370
vaguely modern look socket 1 appeared alongside Intel's wildly popular 486

58
00:04:26,200 --> 00:04:32,070
processor while earlier designs involved soldering

59
00:04:29,620 --> 00:04:37,150
the CPU directly to the board or significant force on the part of the

60
00:04:34,150 --> 00:04:39,340
user to insert or remove them socket one

61
00:04:37,150 --> 00:04:45,550
had a simple mechanism based around a pin grid array very similar to modern

62
00:04:41,620 --> 00:04:48,400
AMD sockets though with a mere 169 pins

63
00:04:45,550 --> 00:04:53,260
but it wasn't just CPU sockets that were getting a facelift expansion slots were

64
00:04:50,830 --> 00:04:58,000
also changing at that time and it was about time as the ancient is a standard

65
00:04:56,290 --> 00:05:04,900
had been used since the days of the original IBM PC in 1994 PCI started

66
00:05:02,770 --> 00:05:11,020
becoming popular in consumer pcs followed by the short-lived AGP for

67
00:05:07,810 --> 00:05:14,919
graphics cards in 1997 and PCI Express

68
00:05:11,020 --> 00:05:16,750
which is still with us today in 2004 but

69
00:05:14,919 --> 00:05:21,010
what about onboard networking in audio well in the mid 1980s there were a

70
00:05:19,060 --> 00:05:25,750
number of proprietary networking protocols but since the now-familiar

71
00:05:23,380 --> 00:05:31,270
Ethernet was a relatively simple standard with easy physical construction

72
00:05:27,940 --> 00:05:33,760
it became the go-to for networking in

73
00:05:31,270 --> 00:05:38,080
the late 80s and again its simplicity meant that it quickly spread to PC

74
00:05:35,800 --> 00:05:42,310
motherboards in the early 1990s and although sound cards also started

75
00:05:40,450 --> 00:05:46,660
appearing on the market in the late 80s and early 90s and we had little internal

76
00:05:45,039 --> 00:05:51,220
speakers that could emit beeps and bleeps for a while we didn't see true

77
00:05:48,940 --> 00:05:58,180
fully functional onboard digital sound hit the mainstream until 1999 when Intel

78
00:05:54,610 --> 00:06:01,090
included the AC 97 standard in its 810

79
00:05:58,180 --> 00:06:05,770
chipset which incidentally was also the first Intel chipset to include

80
00:06:02,860 --> 00:06:10,180
integrated graphics meaning it was no longer necessary to have a separate chip

81
00:06:08,020 --> 00:06:16,120
for video processing be it on the motherboard or on an adapter card so now

82
00:06:14,139 --> 00:06:20,710
that all of these innovations had a clear home on the PC motherboard the

83
00:06:18,639 --> 00:06:25,630
stage was set for refinements made possible by decreasing costs and the

84
00:06:23,620 --> 00:06:29,979
continued miniaturization of components not to mention an increase in processing

85
00:06:27,880 --> 00:06:34,240
capacity to handle lots of different features meaning that these days even

86
00:06:31,990 --> 00:06:41,270
small form-factor motherboards feature RGB headers premium power delivery and

87
00:06:37,469 --> 00:06:43,580
Wi-Fi and of course by lear the 2010

88
00:06:41,270 --> 00:06:47,480
manufacturers also realized that all those bells and whistles are meaningless

89
00:06:45,440 --> 00:06:52,390
without some vaguely threatening heatsinks to show all comers that you

90
00:06:50,000 --> 00:06:56,480
mean business speaking of meaning business do you mean

91
00:06:54,680 --> 00:07:00,800
business when it comes to keeping prying eyes away from your online activity then
