Computer Character Set Tables

I had really great plans when I started this set of Computer Character Tables, but I never finished it. This site http://www.oocities.org/mikes_javascript/hex_table_ascii.html has all the tables that I was planning to put here plus a few more.

EBCDIC Character Set

EBCDIC stands for Extended Binary Coded Decimal Interchange Code or something close to that. It is the character set used on most IBM mainframe computers which run MVS, DOS/VSE, and VM/CMS. Check out a better EBCDIC table.

FIELDDATA Character Set

Field Data or FIELDATA is used on the orginial UNIVAC mainframes. Its a 6 bit character set. The Univac 1100 series computers use FIELD DATA. Check out a better Fieldata table.

FIELDATA Character Set

Field Data or FIELDATA is used on the orginial UNIVAC mainframes. Its a 6 bit character set. The Univac 1100 series computers use FIELD DATA. Check out a better Fieldata table.

BCD Character Set

BCD was used on Honeywell and older IBM computers. I beleive it was before EBCDIC. Check out a better BCD table.

Baudette Character Set

A lot of devices that used paper tape or punched paper tape use Baudette codes or the Baudette character set. Check out a better Baudette table.

UNIVAC Character Set

Field Data or FIELDATA is used on the orginial UNIVAC mainframes. Its a 6 bit character set. The Univac 1100 series computers use FIELD DATA. Check out a better Fieldata table.

IBM Character Set

Punched Card Character sets

This site shows how to make 80 column punched card in the ASCII, EBCDIC, and Field Data character sets. http://www.oocities.org/mikes_javascript/hex_cardpunch.html. Just what you need if you have some old card punch equipment around :)

Morse Code Character Set

Just for fun I once wrote some code that allowed a 68HC11 Motorola microprocessor to display Morse Code on a LED. The LED played the words from the song In-A-Gadda-Da-Vida written by the band "Iron Butterfly". The LED was on a machine used to manufactor semi-conductors and when it was flashing (and singing the words to the song In-A-Gadda-Da-Vida) the machine was in a working state. I never found out if any of our customers who used this machine discovered that the LED was singing the song In-A-Gadda-Da-Vida in Morse code. Any how here is a table that shows how to write ASCII and EBCDIC characters in Morse code. http://www.oocities.org/mikes_javascript/hex_morse.html

The words to the son In-A-Gadda-Da-Vida follow:

In-A-Gadda-Da-Vida, honey,
don't you know that I love you?
In-A-Gadda-Da-Vida, baby,
don't you know that I'll always be true?

Oh, won't you come with me
and take my hand?

Oh, won't you come with me
and walk this land?
Please take my hand!

Braille Character Set

This site shows how to display ASCII or EBCDIC characters in Braille. I guess this is something you need to know if you to write software for blind people to read. http://www.oocities.org/mikes_javascript/hex_braille.html

¹ - This ASCII chart contains the special characters used on M/S DOS and windows. The characters from decimal 128 to 255 are often not defined or used differently on other computers. ASCII stands for American StandarD Code Information Interchange.

² - Almost all modern computers execpt IBM Mainframes running the MVS, VM/CMS, DOS/VSE operating systems use ASCII as their native characters set. Among the computers using the ASCII character set are M/S DOS and WINDOWS machines, APPLE, UNIX, LINUX, DEC, HONEYWELL, UNIVAC, UNISYS, Bourough, SUN, SOLARIS, IBM RS/6000, IBM SYSTEM 3

³EBCDIC is used mostly by IBM Mainframes that use the MVS, VM/CMS, and DOS/VSE operating systems. TSO, IMS, CICS, TSO/SPF are products that run on these computers. The RCA SPECTRA computers which evolved into the UNIVAC VS/9 computers also used EBCDIC. EBCDIC stands for Extended Binary Coded Decimal Interchange Code

⁴These control keys are generally used with the ASCII Character set The decimal number is the code generated when the CNTL key is pressed along with another key.

⁵ - BCD is predisor of EBCDIC. It stands for Binary Coded Decimal

⁶ - FIELDDATA - This characters was the orginal character set used on the UNIVAC 1100 computer which runs the EXEC VIII operating systems. These computers evolved into UNISYS computers. They also support ASCII.

⁷ Packed Decimal - explain ⁸Baudette
