KY11-LB Programmer's Console

The KY11-LB Programmer's Console was an option for the PDP-11/04 and the PDP-11/34 which provided the functionality of a conventional 'lights and switches' front panel.

It consisted of a front panel, an M7859 quad card which plugged into any available UNIBUS SPC slot in the backplane holding the CPU, and a 20-conductor flat cable which connected the two.

The front panel had an octal keypad, a 6-digit LED display which showed address and data information, and the following function keys:

• CLR - Clear
• LAD - Load Address
• DIS AD - Display Address
• LSR - Load Switch Register
• EXAM -Examine
• DEP - Deposit
• CNTRL - Control - Used to enable the following keys:
• INIT - Initialize
• HALT/SS - Halt/Single-Step (the latter without 'Control')
• CONT - Continue
• START
• BOOT

In addition, several other functions were actuated by use of the 'Control' and various numeric keys.
