Each character is shown with its Unicode equivalent right below and its decimal code at the bottom.
Data was stored in six-bit binary-coded decimal code, with three rows of 32 characters each, or 8-bit EBCDIC.
DEC The punched letter or number is translated into a four bit decimal code.
This allowed the paper tape to be punched in decimal codes which would be converted invisibly into binary and stored in memory while being read.
Although a decimal machine, limited character support was provided by the input/output units converting alphabetical and special characters to a two-digit decimal code.
A tiny assembler program was hand-coded for a new computer (for example the IBM 650) which converted a few instructions into binary or decimal code: A1.
Each character is shown with its Unicode equivalent and its decimal code.
Each sub-system of the model was given a decimal code so that an audit trail could be established for the subsequent detailed analysis.
Data was stored in six-bit binary-coded decimal code, with three rows of 32 characters each, or 8-bit EBCDIC, with the two extra holes located in the top rows.
It's possible, for example, with a traditional PC keyboard to hold down the Alt key and enter the decimal code into the number pad and have that work.
