In the late 90’s in Kraków/Poland, there was an “internet” cafe without internet. It was called “Hardcore” and it basically was a LAN party with 12 computers connected via Coax. All the computers had Voodoo cards, cheap ball mice and horrible CRT monitors, but there was Quake2, Starcraft, Unreal and Half-life ….. it was a magical time back then.
My friend's dad had their entire house wired up with coax ethernet when I was a kid. He'd have all of us come over, and play Command and conquer, or Total Annihilation in various rooms with custom built PC's. I was never a part of the multiplayer games, but I remember the BNC connected ethernet from room to room. I learned a lot about computers as a kid from just tinkering with PC's at their house like they were Lego. LOL
This brings back memories. NE2000 cards, home made coax cables with crimped connectors. During LAN parties, the connection crapped out a lot, due to poor cables/connectors etc.
Aww come on Victor, 10BASE5 thick-net with vampire taps and AUI cables would be even more fun! :D Quick, someone send him a box full of goodies! If you like 3Com I might have some 10/100 switches I could send you... I'll have a look at the junk pile at work 😂 Btw, the AUI is just a connection between an ethernet MAC and PHY layers, nowadays this connection is almost exclusively an internal board interface and known as the MII: *Media Independent Interface* (or GMII for gigabit). SFP/SFP+/QSFP modules also serve the same function of allowing one to change the PHY interface while keeping the MAC separate, it is essentially a pluggable form of MII with power and device enumeration and control signals.
Here is why you need these terminations: If you don't use the them, the signals (electromagnatic waves) will be reflected on the open end of a cable or T-juntion. So the reflected wave is travaling back, which causes interference with the other waves, which causes then failures. If you use the termination these waves will "burned" by the resistor. But the termination has to be matched. This means that the resistor has to have the same resistance as the cable. In the video you had a 50 Ohm resistor, which means the coax cable also has a resistance of 50 Ohm (characteristic impedance). This is indeed a rough explanation of this topic, but I hope this enlightens this a bit for you and if I did a mistake in my explanation I am glad for critic.
I supported a 10Base2, 10Base10, FDDI network in the military.. It was a mix of Cisco, Cabletron (MMAC FDDI), and 3Com Hubs.. Also Novell Netware! In the dorms we ran NE2000 NICs (w/ IPX/SPX over 10Base2 Coax) and played rise of the triad! Windows 3.11 didn't have great network support so we had to boot into DOS and load the LAN and Protocol drivers manually. This brings back memories.. Now I'm supporting Cisco Nexus 40Gig networks and more cool stuff..
I love that he says then it just works. I remember when we did gamer night and used this network... Most of the night was used to make the network and when we finally got it to work we didn't want to game anyway 😂😂😂
Hi Victor, love your channel. This brought back memories. I had the very same hub at home to network two or three computers together. Lot of fun and frustration getting it to work. I also worked in a large hospital that had hundreds of stand alone computers and the hospital just installed a backbone running up the center of a 10 story hospital wing connecting two buildings. They installed a 3COM network computer with a hard disk expansion - something like 300 MB of disk space. We just started to install new computers using those T pieces. I was responsible for configuring that 3COM unit so regularly connected and disconnected my PC onto the network - always removing the termination device. How silly. Again a lot of fun. Thanks for a great video. Greetings from Australia.
Well done Victor, brings back memories...;I supported many customers with these technologies in those times...many times a defective terminators caused major network issues..fun looking for the faulty one when lots of PC's are connected ;-)
Collision doesn’t mean something is wrong with the network. Hubs are 1:2 duplex, so only one device may transmit at a time. If 2 devices try to transmit at once, this is a collision. In this case, both devices must stop transmitting and wait for a random amount of time to attempt again.
The hub always had the problem with the collisions. That only got better with the switch. They can send the data in the right direction and thus reduce collisions.
I have a similar setup to 10base2 media conversion but the most fabulous thing is the hub has LED bar graph indicators for bandwidth use so it looks like a cassette desk with 5 vu meters which bounce up and down with the traffic. Better still they are green, yellow and then red. About 10 LED for each meter.
Hello Victor! Do you have network equipment for other old network technologies such as Arcnet, Token Ring or FDDI, if so, make a video about it. Please, thanks!
Yeah, I was going to suggest Token Ring, but Arcnet would also be really cool to see. Totally forgot that ever existed. I had a whole box of Token Ring stuff back in the day, but everything had different connectors, and there was not really an internet to ask. Never got an working network, and now it's up to Victor to redeem.
@@fafler It will be cool to see, bridged/routed heterogeneous old networks technologies in same place working with TCP/IP under DOS/WIN/Unix-like OSes. Also even IPX/SPX with Novell Netware Server.
When I finally got network cards, 10BASE2 was long gone, so I only had 10BASET with a crossed cable. Still got to play StarCraft 1, Rollcage, SimCity 2000 and a few more games over LAN. Was really cool.
I always experienced good connectivity with these cables, simple to handle. Allthough: donot bend :) and donot use powertools near these cables as it would temporarily kill the network connection :) fun times
My Favorite Network Card are an 3com card with 100MBit/s and only one RJ45 Port. The special is that it's an ISA (16Bit) Card and that sound that the ISA Connection cannot handle full 100 MBit/s :)
This was the first type of networking I used in the 90s. Managing the cables was easy and if crimped right never a problem. I always liked this form of networking but obviously rj45 took over and had to adapt. I also used 10base 5 networks in a place i worked was surprised it was still being used as they had only a handful of stations and tried to get them to switch it cat6 but wouldn't.
I used 10base2 to connect 4 computers together for my PCBoard BBS back in the late 80's and early 90's.. Worked great! I was using Novell's Netware Lite to connect the DOS computers. I also used a great product called DesqView that allowed you to run multiple DOS sessions on one computer. Desqview would make a great video for you to create. I can get you the software if you need it. You forgot to add that hubs are still useful today in order to do monitor the network traffic using another computer running wireshark. Enterprise switches have the ability to mirror network ports but using a hub you don't need one.
remember the lan party with bnc? adding players who were to late and disconnect the end cap add user and add rhe end cap before the network or game broke.
I've only come across a few PCI cards with 10base2 or 10base5... I have a 3C900-COMBO with all 3, I think the exact model you have on the bottom right of the shot with all 4 cards. BUT, I never even heard of a 100Mb card with anything but RJ45. That has to be extremely rare.
I had this at school. Often some plug got disconnected and everything stopped. At home we had 25 pin parallel port cables running to all rooms that had a computer. Using some dos too you could transfer files. It only worked from one pc to another. Using a switch we could change what pc was linked to the main pc. These cables must have been much more expensive than coax and not really usable for anything else but file transfer. Later we got this 10base2 much easier. And I gues cheaper. Also actual networked gaming would be possible.
Well for me it's not that old or special since some companies still use it for their old mainframes which I manage. On the other side I was already fiber splicing in 2001 to get 100mbps connections on uplink ports at the first company where I worked. Those 3com cards were the most common cards you could buy and worked right out of the box, even in dos.

And here I thought finding an old 8 port 10 base hub was cool. Yet here's victor breaking out the freaking COAX :D
took me some time finding all the parts :D
No word to explain your hard work
Thanks 😍😍
The ABIT BP6 was the best Mainboard ever. I own one and it was an Server on different LAN Parties with two Celerons.
Aww come on Victor, 10BASE5 thick-net with vampire taps and AUI cables would be even more fun! :D Quick, someone send him a box full of goodies!

That only got better with the switch. They can send the data in the right direction and thus reduce collisions.
Neat video, thanks for sharing! Brings back a lot of fond memories for me of computing in the 90s.
Nice video, brings a lot of good memories :D Before this we even played with direct connection on two PCs via LPT port :D

coax kabels, terminators. oh wat ben ik blij dat we dat niet meer hebben voor een netwerk :P maar wel weer leuke video bart ;)
Next week: Token ring :D

with how many computers on 1 cable run? :)

No one comes late or leaves early! :D
Good....and bad memories, running networks with 10Base2 , 3com old stuff worked well, install many 3C509's

Cool video man
10BASE2 is for rookies. All the cool kids are using 10BASE5. :D
Fantastic!
So what your saying is that termination is very important?
Time for Doom death match under DOS using IPX
ohhhhhhhh . why did i sold 2 times a BP6 ,, i miss that mainboard so much... :-)
Yes great board! and the asus p2b-ds is great :)
Tell me you're Dutch, without telling me you're Dutch.
"Hub"
You can pronounce it as "ay you eye".

hey victor, what do you work as? also, do you have a bf/gf?
