/*
* A low level emulation implementation of the Intergraph InterPro keyboard.
*
* These keyboards have two primary banks of keys. The lower bank consists of
* a total of 67 regular keyboard keyswitches plus a numeric keypad with a
* further 18 keys. The upper bank consists of 57 membrane-style programmable
* function keys in groups of 9, 36 and 12 from left to right.
*
* The following describes the key labels and positions according to the
* standard US English keyboard layout. At least a German keyboard variant is
* known to have existed.
*
* Upper bank keys indicated here with asterisks are printed in white, as are
* all the A*, B* and C* keys; all the others are printed in brown.

* Lower bank keys have up to 3 labels, in shifted and unshifted positions, and

* Alt Mode and Caps Lock keys have locking switches, capturing the key in the
* depressed position, as well as physical leds visible on the keycaps
* themselves. The keyboard also has two physical buttons on its rear face, a
* circular button labelled Boot, and a square one labelled Reset.
*
* The keyboard uses a 1200bps serial protocol to communicate with the host,
* with 1 start bit, 8 data bits, 1 stop bit, and even parity.

*
* The keyboard software relies on a timer interrupt to handle all serial I/O
* and the speaker, while running the main loop which processes commands, and
* scans the upper and lower banks for key status. The lower bank is scanned
* via some unknown external means, possibly the custom Motorola device? This
* method involves clearing and incrementing a counter corresponding to each
* key position, and then reading the selected key state on the T1 input. The
* upper bank is handled via more conventional matrix scan where 6 bits of data
* are read from the bus for each of 15 matrix rows in turn.
*
* The raw count or matrix information is then looked up in various tables (one
* in the on-board rom, and others in the external EPROM), to translate into the
* relevant make/break codes that are then output via the serial interface.
*
* TODO
* - not functional, WIP
* - requires ~500us after start before ready to accept commands
* - keyboard matrix is not yet mapped
* - upper matrix is not mapped
* - arrow keys, keypad and some other keys are not mapped
