Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+
+/*
+ * DEC LK201 and LK401 keyboard driver for Linux (primary for DECstations
+ * and VAXstations, but can also be used on any standard RS232 with an
+ * adaptor).
+ *
+ * DISCLAIMER: This works for _me_. If you break anything by using the
+ * information given below, I will _not_ be liable!
+ *
+ * RJ10 pinout: To DE9: Or DB25:
+ * 1 - RxD <----> Pin 3 (TxD) <-> Pin 2 (TxD)
+ * 2 - GND <----> Pin 5 (GND) <-> Pin 7 (GND)
+ * 4 - TxD <----> Pin 2 (RxD) <-> Pin 3 (RxD)
+ * 3 - +12V (from HDD drive connector), DON'T connect to DE9 or DB25!!!
+ *
+ * Pin numbers for DE9 and DB25 are noted on the plug (quite small:). For
+ * RJ10, it's like this:
+ *
+ * __=__ Hold the plug in front of you, cable downwards,
+ * /___/| nose is hidden behind the plug. Now, pin 1 is at
+ * |1234|| the left side, pin 4 at the right and 2 and 3 are
+ * |IIII|| in between, of course:)
+ * | ||
+ * |____|/
+ * || So the adaptor consists of three connected cables
+ * || for data transmission (RxD and TxD) and signal ground.
+ * Additionally, you have to get +12V from somewhere.
+ * Most easily, you'll get that from a floppy or HDD power connector.
+ * It's the yellow cable there (black is ground and red is +5V).
+ *
+ * The keyboard and all the commands it understands are documented in
+ * "VCB02 Video Subsystem - Technical Manual", EK-104AA-TM-001. This
+ * document is LK201 specific, but LK401 is mostly compatible. It comes
+ * up in LK201 mode and doesn't report any of the additional keys it
+ * has. These need to be switched on with the LK_CMD_ENABLE_LK401
+ * command. You'll find this document (scanned .pdf file) on MANX,
+ * a search engine specific to DEC documentation. Try
+ * http://www.vt100.net/manx/details?pn=EK-104AA-TM-001;id=21;cp=1
