- Apple Macintosh original/512/Plus keyboard
- Emulation by R. Belmont
-
- Port definitions from "IM Underground Volume 1"
- http://bitsavers.org/pdf/apple/mac/IM_Underground_Vol_1_1985.pdf
-
- Key matrix for keyboard:
-
- Cols 0 1 2 3 4 5 6 7 8 Rows
- G B T 5 0 P ; . n/a 0
- H n/a Y 6 8 I K M Enter 1
- F V R 4 - [ ' N Backsp 2
- D C E 3 7 U J / ` 3
- S X W 2 9 O L , Space 4
- A Z Q 1 = ] Ret \ Tab 5
-
- Port 0:
-
- x------- Clock to Mac
- -x------ Caps Lock
- --x----- Row 5 readback (tied to Vcc for keypad)
- ---x---- Row 4 readback
- ----x--- Row 3 readback
- -----x-- Row 2 readback
- ------x- Row 1 readback
- -------x Row 0 readback
-
- Port 1:
-
- x------- Column 8 strobe
- -x------ Column 7 strobe
- --x----- Column 6 strobe
- ---x---- Column 5 strobe
- ----x--- Column 4 strobe
- -----x-- Column 3 strobe
- ------x- Column 2 strobe
- -------x Column 1 strobe
-
- Port 2:
- x--- Command/Apple
- -x-- Shift
- --x- Column 0 strobe
- ---x Data to Mac
-
- The T1 line is "Option".
-
- There is a later M0110 keyboard version which uses a GI PIC1657; we do not have a dump of that version.
