k-bits of Peripheral Devices for Orion 1 machines

The k-bits are the engineers address of the device. It is an 8 bit quantity of odd parity.

14.2.1 The k-bits of magnetic tape decks for the installations are:-

Geographical Name	K-bits
MTA	64
MTB	193
MTC	194
MTD	67
MTE	196
MTF	69
MTG	70
MTH	199
MTI*	200

*For Ericssons this is MTK

14.2.2 The k-bits of the control Flexowriter for the installations are:-

Geographical Name	K-bits
FLX (input) FLO (output)	4 8

14.2.3 The k-bits of card readers for the installations are:-

Geographical Name	K-bits
CRA	224

14.2.4 Line printers and card punches are considered together and their k-bits are in the sequence

97, 98, 100, 103

See the appropriate sub-section of 14.1 for these.

14.2.5 The k-bits of character peripheral devices depends on the distribution of these devices on the character control units. See the appropriate sub-section of 14.1 or the following table.

The k-bits are given after the geographical name
