## 6. NCD keyboards

Some keyboards natively produce Set 3 scancodes. When connected to a PC one will by default see translated Set 3 scancodes. This means that the F9 and F10 keys have make codes 60 and 61 and break codes e0 and e1. Thus, these latter codes are ordinary key release codes here, not protocol codes.

The N-nnn type numbers indicate the number nnn of keys the keyboard has.

## 6.1 A Japanese keyboard using e0 as ordinary scancode

Benjamin Carter <`bcarter@ultra5.cs.umr.edu`> reports:

I recently came into possession of a 97-key keyboard with Japanese markings on the keys. (The keys also have the standard qwerty-characters on them, with the exception of some of the meta-keys (there are 3 keys near the Alt keys on either side of the spacebar with only Japanese characters on them so I don't know what they are). In any case, the keyboard sends out scancodes that work for all the main keys (backspace, letters and numbers, enter, shift), but the numeric keypad, Alt keys, and function keys don't work. I have run the board through `showkey -s`, so I know what scancodes this keyboard sends out. However, the F9 and F10 keys send out 60 and 61, respectively, so their key release events send out e0 and e1, confusing the keyboard driver.

(Compare this with the table giving the translated Set 3 scancodes. The reported codes are almost identical.)

## 6.2 The NCD N-123NA keyboard

There are more keyboards that do not use e0 as escape code. For example, Paul Schulz <`pauls@caemrad.com.au`> reports the same for Sun Type 5 Keyboard with PS/2 connector, NCD model N-123NA. The scancodes are very similar to those given above:

## 6.3 The NCD N-123UX keyboard

Don Christensen reports that his NCD N-123UX keyboard returns scancode Set 3.

## 6.4 The NCD N-97 keyboard

David Monro reports: I have a PS/2 keyboard, an NCD N-97, which shipped with some NCD X terminals and also with some Mips workstations IIRC. This keyboard returns Set 3 keycodes even when its told to be in Set 2. In particular, the release codes for F9 and F10 are e0 and e1. The keyboard ID is ab 85.
