- 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.
