The 1. 40. 1 is considered to be the Model T Ford of the computer industry, because it was mass produced and because of its sales volume. Over 1. 2,0. 00 units were produced and many were leased or resold after they were replaced with newer technology. The 1. 40. 1 was withdrawn on February 8, 1. Historyedit. IBM 1.

IBM 1. 40. 2 Card Read Punch to tape, and transferred output data from tape to the card punch, the IBM 1. Printer, or other peripherals. This allowed the mainframes throughput to not be limited by the speed of a card reader or printer. For more information, see Spooling.

Architectureedit. Console and, below, the Auxiliary Console. Each alphanumeric character in the 1. B,A,8,4,2,1. The B,A bits were called zone bits and the 8,4,2,1 bits were called numeric bits, terms taken from the IBM 8. For digits 1 through 9, the bits B,A were zero, the digit BCD encoded in bits 8,4,2,1. Digit 0 was encoded 8,2. For alphabetic characters the setting of bits was derived from the zone and digit punches of the IBM 8. B,A from 1. 2, B from 1. A from 0 the setting of bits 8,4,2,1 from BCD encoding of the 1 through 9 punches. Thus the letter A, 1. B,A,1. Encodings of punched card characters with two or more digit punches can be found in the Character and op codes table. IBM called the 1. Metro Booming Drum Kits. BCD, even though that term describes only the decimal digit encoding. The 1. 40. 1s alphanumeric collating sequence was compatible with the punched card collating sequence. Associated with each memory location were two other bits, called C for odd parity check and M for word mark. Each memory location then, had the following bits C B A 8 4 2 1 MThe 1. Each character was addressable, addresses ranging from 0 through 1. A very small number of 1. Some operations used specific memory locations those locations were not reserved and could be used for other purposes. Read a card stored the 8. Index registers 1, 2 and 3 were in memory locations 0. Punch a card punched the contents of memory locations 1. Write a line printed the contents of memory locations 2. The 1. 40. 1s instruction format was. A or I or unit address B address modifier. Opcodes were one character. Memory addresses I a branch target, A and B data and unit address were three characters. The opcode modifier was one character. Instruction length was then 1, 2, 4, 5, 7, or 8 characters. Most instructions had to be followed by a word mark a requirement commonly met by the word mark with the opcode of the next instruction. See Character and op codes for a list of operations. A three character memory address in an instruction was an encoding of a five digit memory address. The three low order digits of the five digit address, 0. The zone bits of the high order character specified an increment as follows A 1. B 2. 00. 0, B and A together 3. The zone bits of the low order character specified increments of 4. IBM 1. 40. 6 Storage Unit. For example, the three character address I9. The zone bits of the middle character of a three character memory address could specify one of three index registers, one of many optional features. Operands referenced by the A address and B address were a single memory location, a variable length field, or a variable length record. Variable length fields were addressed at their low order highest addressed position, their length defined by a word mark set at their high order lowest addressed position. When an operation such as addition was performed, the processor began at the low order position of the two fields and worked its way to the high order, just as a person would when adding with pencil and paper. The only limit on the length of such fields was the available memory. Instructions applicable to variable length fields included Add, Subtract, Multiply, Divide, Compare, Move Characters to A or B Word Mark, Move Characters and Edit. One or more adjacent variable length fields could make up a variable length record. A variable length record was addressed at its high order position, its length defined by a group mark character with a word mark or a record mark character in its low order position. The instruction Move Characters Record or Group Mark could be used to assemble a block of records. A variable length record, or block of records, to be written to magnetic tape was addressed at its high order position, its length defined by a group mark character with a word mark immediately following its low order position. A sequence of operations on adjacent fields could be chained, using the addresses left in the address registers by the previous operation. For example, addition of adjacent data fields might be coded as A 7. A 6. 95,8. 45, A 6. With chaining, this could be coded as A 7. A, A omitting data address from the 2nd and 3rd instructions. Booting and sample programeditWhen the LOAD button on the 1. Card Read Punch was pressed, a card was read into memory locations 0. That was always the dyadic Set Word Mark it was the only instruction not requiring a following word mark to set word marks for the two following instructions. Execution of instructions in the card deck continued, loading the program into memory, setting word marks, and then branching to the programs start address. One card programs could be written for various tasks. Commonly available were a one card program to print the deck of cards following it, and another to duplicate a deck to the card punch.
