/*********************************************************************
Asem AM 100 90-key keyboard
This detached keyboard is an upgraded cousin of the TK10 keyboard
found on the AM 64. The BASIC keywords produced with the function
modifier key are very similar, with no spelling errors here.
The PCB is silkscreened “MAK-II KEYBOARD 8039”.
Much like KB200, it has a typewriter-style layout similar
to early IBM PC keyboards, with the function keys in the top row
rather than clustered on the left. Very unusually for an Apple II
clone keyboard, it has an onboard speaker that emits keyclicks
when F9 is toggled on.
Keycodes are sent serially over a 9-wire cable and converted to
parallel by a tiny daughterboard with a LS164 and a LS374.
The macro definition feature appears to work this way:
— Press UDFN and a digit key together to begin a definition.
— Press UCLS to end the definition.
— Press Alt and the digit to invoke the key macro.
— Press Ctrl and UCLR together to clear all macros.
