+ Dolphin / Dauphin
+
+ 2010-04-08 Skeleton driver.
+ 2012-05-20 Fixed keyboard, added notes & speaker [Robbbert]
+ 2013-11-03 Added cassette [Robbbert]
+
+ Minimal Setup:
+ 0000-00FF ROM "MO" (74S471)
+ 0100-01FF ROM "MONI" (74S471)
+ 0200-02FF RAM (2x 2112)
+ 18 pushbuttons for programming (0-F, ADR, NXT).
+ 4-digit LED display.
+
+ Other options:
+ 0400-07FF Expansion RAM (8x 2112)
+ 0800-08FF Pulse for operation of an optional EPROM programmer
+ 0C00-0FFF ROM "MONA" (2708)
+ LEDs connected to all Address and Data Lines
+ LEDs connected to WAIT and FLAG lines.
+ Speaker with a LED wired across it.
+ PAUSE switch.
+ RUN/STOP switch.
+ STEP switch.
+ CLOCK switch.
+
+ Cassette player connected to SENSE and FLAG lines.
+
+ Keyboard encoder: AY-5-2376 (57 keys)
+
+ CRT interface: (512 characters on a separate bus)
+ 2114 video ram (one half holds the lower 4 data bits, other half the upper bits)
+ 74LS175 holds the upper bits for the 74LS472
+ 74LS472 Character Generator
+
+ NOTE: a rom is missing, when the ADR button (- key) is pressed,
+ it causes a freeze in nodebug mode, and a crash in debug mode.
+ To see it, start in debug mode. g 6c. In the emulation, press the
+ minus key. The debugger will stop and you can see an instruction
+ referencing location 0100, which is in the missing rom.
+
+ Keys:
+ 0-9,A-F hexadecimal numbers
+ UP - (NXT) to enter data and advance to the next address
+ MINUS - (ADR) to change the address to what is shown in the data side
+ Special keys:
+ Hold UP, hold 0, release UP, release 0 - execute program at the current address (i.e. 2xx)
+ Hold UP, hold 1, release UP, release 1 - execute program at address 0C00 (rom MONA)
+ Hold UP, hold 2, release UP, release 2 - play a tune with the keys
+ Hold UP, hold 3, release UP, release 3 - decrement the address by 2
+ Hold MINUS, hold any hex key, release MINUS, release other key - execute program
+ at the current address-0x100 (i.e. 1xx).
+
+ If you want to scan through other areas of memory (e.g. the roms), alter the
+ data at address 2F9 (high byte) and 2FA (low byte).
+
+ How to Use:
+ The red digits are the address, and the orange digits are the data.
+ The address range is 200-2FF (the 2 isn't displayed). To select an address,
+ either press the UP key until you get there, or type the address and press
+ minus. The orange digits show the current data at that address. To alter
+ data, just type it in and press UP.
+
+ To play the reflexes game, hold UP, press 1, release UP, release 1.
+ The display will show A--0 (or some random number in the last position).
+ Press any odd-numbered key (B is convenient), and read off the reaction time.
+ After a short delay it will show '--' again, this is the signal to react.
+ It doesn't seem to reset the counters each time around.
+
+ TODO:
+ - Find missing roms
+ - Add optional hardware listed above
+ - Cassette is added, but no idea how to operate it.
+
+ Thanks to Amigan site for various documents.
