00:00:07.859 --> 00:00:14.670
just adding a CPU a stick of RAM a storage device and a power supply to a

00:00:12.480 --> 00:00:20.220
mini ITX motherboard will give you a small and fully functional computer in a

00:00:17.910 --> 00:00:24.810
matter of minutes and this is possible because of how many different functions

00:00:22.230 --> 00:00:30.480
the average motherboard combines into one little slab of like fiberglass metal

00:00:28.170 --> 00:00:35.700
and silicon but it wasn't always like this in fact early electronics didn't

00:00:33.239 --> 00:00:40.440
have anything resembling the lovely green boards with black integrated

00:00:37.890 --> 00:00:45.030
circuits that were used to today instead it was common to see individual full

00:00:42.719 --> 00:00:50.270
sized wires linking every capacitor resistor and other component necessary

00:00:47.910 --> 00:00:55.590
to make up a full computer system unsurprisingly this approach took up

00:00:52.920 --> 00:01:01.590
tons of space added a bunch of weight and was relatively fragile meaning that

00:00:59.190 --> 00:01:06.299
the printed circuit board took off in popularity pretty quickly starting in

00:01:03.660 --> 00:01:12.390
the 1950s it should be noted however that these early PCBs were still a far

00:01:09.659 --> 00:01:16.710
cry from the RGB motherboard that you might have sitting in your computer

00:01:13.740 --> 00:01:21.650
right now while back then a simple device like a radio might have gotten

00:01:19.110 --> 00:01:26.189
away with using just one PCB full-fledged computers needed many

00:01:24.360 --> 00:01:31.439
circuit boards to handle different functions connected by a backplane that

00:01:29.189 --> 00:01:35.939
you might consider to be a forerunner of the modern motherboard unlike true

00:01:34.110 --> 00:01:41.130
motherboards though these back planes tended to be dumb connections with no

00:01:38.610 --> 00:01:46.079
actual logic that consisted of little more than a bunch of slots lined up in a

00:01:43.530 --> 00:01:52.110
row so that other expansion cards could be plugged in for example the Altair

00:01:48.750 --> 00:01:55.710
8800 used one slot to insert a processor

00:01:52.110 --> 00:01:59.520
another for memory and so on it wasn't

00:01:55.710 --> 00:02:02.130
until 1981 that we got a big upgrade the

00:01:59.520 --> 00:02:10.170
planar board in the original IBM PC featured an Intel 8088 CPU built in

00:02:06.210 --> 00:02:13.319
memory and actual external IO so it was

00:02:10.170 --> 00:02:16.420
far more than just a glorified bundle of

00:02:13.319 --> 00:02:18.250
wire like smooshed together all you

00:02:16.420 --> 00:02:23.140
could connect directly to it was a keyboard and a cassette drive but it

00:02:21.070 --> 00:02:27.040
also included a handful of expansion slots that didn't look too different

00:02:25.000 --> 00:02:31.030
from what we're used to today and those slots were important because

00:02:28.300 --> 00:02:36.280
motherboards were still so simple that they didn't have features that we

00:02:32.890 --> 00:02:38.620
consider basic now like drive headers

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

00:02:41.560 --> 00:02:49.900
would need a standalone disk interface card and we didn't see modern memory

00:02:47.020 --> 00:02:55.270
modules that fit into RAM slots until the mid-1980s either by the late 80s

00:02:53.110 --> 00:02:59.920
though engineers had fully embraced the goal of integrating more and more

00:02:57.730 --> 00:03:06.010
functions onto the motherboard and so little ICS called super i/o chips were

00:03:03.430 --> 00:03:10.810
becoming more common these functioned like rudimentary versions of a modern

00:03:08.170 --> 00:03:17.350
chipset they provided drive controllers ports for printers mice keyboards and

00:03:13.480 --> 00:03:19.630
other devices and the systems BIOS now

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

00:03:22.299 --> 00:03:29.530
space and they were much more cost effective than expansion cards setting

00:03:27.340 --> 00:03:34.630
the stage for full-featured modern motherboards around the same time in

00:03:32.019 --> 00:03:41.440
1987 specifically we've got the first ever integrated VGA graphics chips when

00:03:38.140 --> 00:03:44.769
IBM released model 50 of their almost

00:03:41.440 --> 00:03:47.320
famous personal system - unlike modern

00:03:44.769 --> 00:03:51.040
integrated GPUs though this was a chip that was affixed to the motherboard

00:03:49.209 --> 00:03:57.549
instead of being built into the CPU itself a paradigm that we saw again

00:03:53.950 --> 00:04:00.880
starting in the mid-1990s as 3d GPUs

00:03:57.549 --> 00:04:03.220
like the s3 trio and the ati rage series

00:04:00.880 --> 00:04:08.470
appeared on motherboards obviating the need for a separate card for basic use

00:04:05.739 --> 00:04:13.840
though GPUs that were soldered onto motherboards began to disappear in favor

00:04:10.780 --> 00:04:16.450
of ones built into CPUs by the mid 2010

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

00:04:20.320 --> 00:04:27.370
vaguely modern look socket 1 appeared alongside Intel's wildly popular 486

00:04:26.200 --> 00:04:32.070
processor while earlier designs involved soldering

00:04:29.620 --> 00:04:37.150
the CPU directly to the board or significant force on the part of the

00:04:34.150 --> 00:04:39.340
user to insert or remove them socket one

00:04:37.150 --> 00:04:45.550
had a simple mechanism based around a pin grid array very similar to modern

00:04:41.620 --> 00:04:48.400
AMD sockets though with a mere 169 pins

00:04:45.550 --> 00:04:53.260
but it wasn't just CPU sockets that were getting a facelift expansion slots were

00:04:50.830 --> 00:04:58.000
also changing at that time and it was about time as the ancient is a standard

00:04:56.290 --> 00:05:04.900
had been used since the days of the original IBM PC in 1994 PCI started

00:05:02.770 --> 00:05:11.020
becoming popular in consumer pcs followed by the short-lived AGP for

00:05:07.810 --> 00:05:14.919
graphics cards in 1997 and PCI Express

00:05:11.020 --> 00:05:16.750
which is still with us today in 2004 but

00:05:14.919 --> 00:05:21.010
what about onboard networking in audio well in the mid 1980s there were a

00:05:19.060 --> 00:05:25.750
number of proprietary networking protocols but since the now-familiar

00:05:23.380 --> 00:05:31.270
Ethernet was a relatively simple standard with easy physical construction

00:05:27.940 --> 00:05:33.760
it became the go-to for networking in

00:05:31.270 --> 00:05:38.080
the late 80s and again its simplicity meant that it quickly spread to PC

00:05:35.800 --> 00:05:42.310
motherboards in the early 1990s and although sound cards also started

00:05:40.450 --> 00:05:46.660
appearing on the market in the late 80s and early 90s and we had little internal

00:05:45.039 --> 00:05:51.220
speakers that could emit beeps and bleeps for a while we didn't see true

00:05:48.940 --> 00:05:58.180
fully functional onboard digital sound hit the mainstream until 1999 when Intel

00:05:54.610 --> 00:06:01.090
included the AC 97 standard in its 810

00:05:58.180 --> 00:06:05.770
chipset which incidentally was also the first Intel chipset to include

00:06:02.860 --> 00:06:10.180
integrated graphics meaning it was no longer necessary to have a separate chip

00:06:08.020 --> 00:06:16.120
for video processing be it on the motherboard or on an adapter card so now

00:06:14.139 --> 00:06:20.710
that all of these innovations had a clear home on the PC motherboard the

00:06:18.639 --> 00:06:25.630
stage was set for refinements made possible by decreasing costs and the

00:06:23.620 --> 00:06:29.979
continued miniaturization of components not to mention an increase in processing

00:06:27.880 --> 00:06:34.240
capacity to handle lots of different features meaning that these days even

00:06:31.990 --> 00:06:41.270
small form-factor motherboards feature RGB headers premium power delivery and

00:06:37.469 --> 00:06:43.580
Wi-Fi and of course by lear the 2010

00:06:41.270 --> 00:06:47.480
manufacturers also realized that all those bells and whistles are meaningless

00:06:45.440 --> 00:06:52.390
without some vaguely threatening heatsinks to show all comers that you

00:06:50.000 --> 00:06:56.480
mean business speaking of meaning business do you mean

00:06:54.680 --> 00:07:00.800
business when it comes to keeping prying eyes away from your online activity then
