The VT220 was a terminal produced by Digital Equipment Corporation from 1983 to 1987.[1][2]

Hardware [link]

The VT220 improved on the earlier VT100 series of terminals with a redesigned keyboard, much smaller physical packaging, and a much faster microprocessor. To meet the needs of various national regulatory agencies[citation needed], the VT220 was available with CRTs that used white, green, or amber phosphors.

Several of the VT2xx models were pyramid shaped, allowing them to sit on a table top, leaving the surface of the display at an angle to the user; this angle could be adjusted. Because it was lower than head height, the result was an especially ergonomic terminal. The LK201 keyboard supplied with the VT220 was one of the first full length low profile keyboards available; it was developed at DEC's Roxbury, Massachusetts facility.

The VT240 and VT241 were variants of the VT220, both capable of displaying vector graphics using the ReGIS instruction set. The VT241 was equipped with a color screen. The successor of the VT220 was the VT320, itself followed by the VT420.

DEC VT220 connected to the serial port of a modern computer.

Software [link]

The VT220 was designed to be compatible with the VT100, but added features to make it more suitable for an international market. This was accomplished with the National Replacement Character Set feature (e.g., Multinational Character Set) and support for 8-bit downloadable character sets.

Without A Head

by: Texas In July

I saw you die inside today
I saw you die inside today
Its gonna make things hard for you
But I see the will in you to change
The way you've been
Has me wishing the best for you
Only the best for you
Dead space replaced my memory back
The weight of your world has come over me
It's never been the same
Are you the one to blame?
If I could only ask for a better way
A better way to save you
Chop block with your head on it
You can cut it off
Do what you want with it
Who need a head when you don't use it?
Abused and polluter
This is not an illusion
I saw you die inside today
I saw you die inside today
It's gonna make things hard for you
You take a shot at me
And in the end you'll see
That your words will chain you down
Committed all alone
And in the time to come
You'll grip the hell that you put me through
Chop block with your head on it
You can cut it off
Do what you want with it
Who needs a head when you don't use it?
Abused and polluted
This is not an illusion
There's one illusion that I can see
It's that you need that thing
Bow down to the bottle
You're gonna lose your family
I've seen you stand taller than this
I've seen you stand taller
Face first in the earth
Addiction suffocates
Or it separates
Whichever one comes first
The weight of your world has come over me
It's never been the same
Are you the one to blame?
If I could only ask for a better way
