Here is a typical traceiver, which can connect to twister pair network with blazing 10 Mbps providing us a practical way to connect HP 700/RX to the world. #hp #hp700rx #ethernet

But how about that mysterious AUI? AUI stands for Attachment Unit Interface, and it allows different types of network ports to be connected to the host machine, 700/RX. The network interface is provided by Medium Attachment Unit, MAU, aka tranceiver. #hp #hp700rx #ethernet

Third important external connection is the network. With 700/RX we have two options, thin ethernet (10Base-2) and something called as AUI. Thin ethernet used to be the way to cable your network back then, but nowadays it is practically extinct. #hp #hp700rx #ethernet

Fortunately 700/RX also supports separate sync signals, known as RGBHV or digital sync in HP world. Even better, it allows you change display mode at the boot screen. Interrupt boot process with a space and graphics mode can be selected with numeric keypad. @hp #hp #hp700rx #vga

700/RX also has a very familiar looking VGA connector at the back and a regular VGA monitor can be connected to it. However, HP have had a habit of using VGA signaling with sync on green, RGsB, which is not universally supported. #hp #hp700rx #vga #monitor #rgsb

HP-HIL bus found from 700/RX and other HP devices from the era allows wide variety of input devices to be connected, however, they are much harder to come by nowadays than common PS/2 keyboards and mice.

Let’s take a closer look at some of the connections in the HP 700/RX - the keyboard and mouse. The 700/RX is new enough that, besides HP's own Human Interface Link (HP-HIL), it also includes standard PS/2 connections for both the keyboard and mouse. @hp #hp700rx #hphil #ps2

HP 700/RX has a wide variety of connections to the outside world, a similar set that you can find from almost any workstation from the time. Most of these have been replaced with Universal Serial Bus aka USB in modern devices. @hp #hp700rx #connectivity #usb

i960 processor on 700/RX motherboard.

Speaking of HP 700/RX, its processor is a bit on the unusual side - Intel i960 running on 25 Mhz. i960 is more common on the embedded systems but never was popular processor on the desktop.

Apparently you can still connect HP's X terminal 700/RX from 1992 or so to a modern Linux, Ubuntu 24.10 with a really colorful way. #hp #hp700rx #ubuntu #x11 #acid #backwardcompability #rt4k
