Apple Numeric Keypad IIe - with pics
« on: Wed, 23 December 2015, 01:17:52 »
Just wanted to share this old beauty that I picked up recently.  It's the older style, with the nice thick domed doubleshot keycaps and I'm assuming linear ALPS switches.  It also has the older style font, which I really like.  The caps feel a lot like the Signature Plastics spherical ABS doubleshots (like the Round 4 and Round 5 Honeywell group buy keys).  It looks like they only made this older style a few years, as the "newer" ones look like this:  http://shrineofapple.com/blog/2011/05/27/appleiie-numeric-keypad/ .  It's also a pretty low serial number.

I know these aren't that rare and most of you have probably seen them, but I just wanted to have one and share it with y'all.  I grew up with an Apple IIe and it was how I first learned computing and BASIC, but I live in an apartment and move somewhat often, so owning a IIe rig is not in the cards right now.  Unfortunately by the time I can easily own one, they'll probably cost thousands.  So this helps give me a little slice of that nostalgia in a small package.   :)

It could use some retr0brite, but after doing that on a few old AEK's, I think I might actually not do it.  It ends up more like the original color, but a little bit splotchy looking in some areas so I'm on the fence.

I also found some info on the connector and pinouts, if anyone knows how to actually bring this to PS2 or USB let me know.  I already have an ADB to PS2 converter, if that helps.

Apple //e Numeric Keypad cable

(This is from a Csa2 post by Mark Wade.)

To construct a suitable internal cable for a IIe numeric
keypad you need a female Dsub-15 to 11 pin female header.
If the female Dsub-15 is numbered like this:

           Dsub-15 (female)
    ,-------------------------.
    \ 08 07 06 05 04 03 02 01 /
     \ 15 14 13 12 11 10 09  /
      `---------------------'

And the 11 pin header is numbered like this:
 _____________________________________
|                                     |
|  11  10  9  8  7  6  5  4  3  2  1  |
|_____________________________________|

Then:

Dsub-15 | Header
________|_______
   12   |   11
   11   |   10
   10   |   9
    9   |   8
   NC   |   7
    7   |   6
    6   |   5
    5   |   4
    3   |   3
    2   |   2
    1   |   1

The header is as viewed on the motherboard. The Dsub-15 is the
female connector that you would plug the keypad into.

Found it ;D Looks like you can access key matrix directly with those pins.

Code: [Select]
Pin             Name        Description                               
-----------------------------------------------------------------------
1,2,5,3,4,6     Y0-Y5       Y-direction key-matrix connections         
7               n.c.                                                   
9,11,10,8       X4-X7       X-direction key-matrix connections 

See p.188.

Very cool!  I had no idea they made a separate num pad.

I remember us playing Oregon Trail on those machines back in the day.

Ooh, Alps SKCC black! Never seen them before. How do they compare to other linear switches (and other SKCCs if you have them)?
Check my keyboard video reviews:

Thanks to the info in this thread (and a hefty dose of help from patient folks in the QMK Discord) I was able to successfully get a Numeric Keypad IIe working with QMK and connected via USB! The firmware is now in the QMK repo (in /converter/numeric_keypad_iie) and I've also shared some more info (and pics) on a page I published:https://adam.lol/bucket/numeric-keypad-iie/

Hope this helps anyone else trying to use one of these with a modern setup. :)
