@webmink maybe some #legacy #Networking fans want some #MAUI / #AUI and other partd for #Retro-#Ethernet?

Pretty shure some #CCCamp / #40C3 attendee from the #UK would like to get their hands on the other #10Base2 / #10Base5 gear...

  • Maybe take inventory on what you got there?

Attached: 1 image Also there *used to be external #Ethernet "#Modems"*... - Like [*this one*](https://en.wikipedia.org/wiki/File:Accton-etherpocket-sp-parallel-port-ethernet-adapter.jpg) that can be found on the [History section](https://en.wikipedia.org/wiki/Ethernet#History) of the Ethernet article on #Wikipedia... So it's not impossible to facilitate something like that. - Just a 10/100BASE-T adaptor connected via RS-232...

Now some folks may say: "Why don't you just get a regular-ass #AUI like a #NormalPerson?"

1. Simply because noone but the most tech-masochistic folks want to deal with like #coax cables, #VampireTaps, huge #MAUI boxes and rare vintage stuff + overhead to get a slow & underwhelming network experience. Pretty shure neither @ncommander nor @TechTangents would either.

2. The few late-era #10BaseT-based AUIs do exist but they are long out of production and thus quite expensive. And if you are on #10Base2 or even #10Base5 good luck finding a still working #switch that isn't sold by a #scalper like #ersazza way above #MSRP+#inflation!

3 An AUI is just an Interface port / media converter similar to #SFP & GBIC and necessitates a NIC already inside the machine.

4. AUIs are not just long outdated but also way more inflexible, whereas basically anything from an #Apple2 up to the latest #Android-#Tablet can be adapted cheaply to do #RS232 #serial and send AT commands to a #Modem.

5. Twisted-Pair Ethernet is cheap, commonplace and still supported and pretty much forwards- and backwards compatible. 10BaseT will run on Cat.3 but also on Cat.5 and even Cat.8 cables (In case one wants to hookup a vintage computer on a 40GBase-T port for no reason but to see if the switch does negotiate proper 10Base-T.

6. Because it's useful...

7. as said before: AUI port would be nice to have but not necessary...

8. it would allow Network access similar to #dialup abeit without the need for existing #PSTN infrastructure like @c3isdn has...

Everyone and their mom has a #Wifi232 to get their #VintageComputer online, but I wounder if there's a #wired (#LAN) option instead.

Background: In my area, 2,4 GHz WiFi is so overcrowded that it's basically unuseable and also because Ethernet is more reliable.

I don't mind if it looks like a MAU but with like a unmanaged 4-port Gigiabit Switch for #10Base2 / #10Base5 - lookalike "passthrough" and internal 10 MBit/s port so it can be used to directly link units or be hooked up to a switch. Similar to FriendlyNet

So technically it's closer to a DEC DELNI than real AUI but if someone wants to implement an #AUI and even add a an AAUI adaptor cable I'm not gonna tell anyone not to.

之前聊了 #10BASE2 以及 #10BASE5
有提到後來同軸電纜就慢慢退出區域網路接取標準
但是在廣域網路( #WAN ) 接取標準卻不是如此

在前幾篇就已經有象友提到,一些國家過去曾使用有線電視電纜進行網路接取。
確實,如:美國、中國,這樣地域廣大的國家,在過去因為有線電視作為基礎建設,有大量鋪設到許多人口非密集區;然而,這些地方如果要重新鋪設纜線作為網際網路傳輸,可能不敷成本。

#DOCSIS 就這樣出現了,嘗試透過已經存在的有線電視纜線 ( #Cable ) 來進行網際網路的傳送,應用在許多無法重新鋪設光纖線路的地區,而負責制定 DOCSIS 的組織 #CableLabs 也不斷的對 DOCSIS 進行提速,以目前最新的 4.0 版本也已經可以達到下載 10G 上傳 6G 的速度,與光纖常用的 #GPON#EPON 相比也絲毫不遜色。

臺灣的有線電視業者也用 DOCSIS 提供有線網路接取服務,而目前政府的政策下逐步在更換為光纖,改為所有訊號都改為光纖傳送。

前篇聊到了 #10BASE2
這篇來聊一下另外一個 10Mbps 的接取標準 #10base5

其實在過去有另外一個說法
10Base2 被稱為 #thinnet
而 10Base5 稱為 #thicknet
後者比前者約 5 年以前推出
兩者都是使用同軸電纜
並且都運行在 10Mbps

而 10Base5 使用的電纜線更加的粗
在使用上 10Base5 的概念更像是幹線的存在
同樣與 10Base2 一樣可以讓多個節點運行在同一個內網內
不過接取的方式有很大的不同

接入網路的接頭不是使用 #BNC 而是 #N端子 以外
還有另外一個接取方式稱為 #吸血鬼接口 Vampire tap
使用端子對同軸線纜進行穿刺再由收發器轉接為 #AUI 接口
電腦或是終端裝置再透過 AUI 線再接到 #網路卡

而後來 10Base2 出現
由於其低成本、線纜鋪設難度低以及接取的方式也簡單的多
也讓 10Base5 快速的退市

#10BaseT 的出現讓同軸電纜開始慢慢退出區域網路接取標準
