EA Car Computer
Described in Electronics Australia magazine during 1982.
Construction and usage: http://messui.the-chronicles.org/comp/eacc.pdf
The only RAM is the 128 bytes that comes inside the CPU.
This computer is mounted in a car, and various sensors (fuel flow, etc)
are connected up. By pressing the appropriate buttons various statistics
may be obtained.
Memory Map
0000-007F internal ram
4000-7FFF ROM
8000-BFFF 6821
C000-FFFF ROM (mirror)
Setting up: You need to enter the number of expected pulses from the fuel
and distance sensors. Paste this: 5 6M123N 7M400N (start, set litres cal to
123 pulses. set km cal to 400 pulses). Then paste this: 1950M0N 1845M0N (set
petrol tank capacity to 50 litres, set current amount of petrol to 45).
Now enter: 28M100N (the journey is 100km). Press 5 to start the journey.
All settings are saved in nvram.
Stats you can see while travelling:
0 - time elapsed
08 - time remaining
1 - fuel used
18 - fuel left
2 - km travelled
28 - km remaining
29 - km that could be travelled with the fuel you have left
3 - speed now
39 - average speed
4 - fuel consumption now (litres per 100km)
49 - fuel average consumption

To Use:
- Press MINUS to enter data input mode
- Press UP or DOWN to cycle through addresses
At the moment Paste cannot be tested, but if it worked, you could
paste this in: -0F0011^22^33^44^55^66^77^88^99^
It seems the only way to exit each mode is to do a Soft Reset.

http://digitarworld.uw.hu/z80.htm
All commands must be entered in uppercase, and since the capslock
doesn't work, you need to hold the shift key down.
There is next to no error checking, for example the T command
is to set the time. Entering T by itself will set the time to
99:99:99, while G will cause a jump to 9999 and so forth. Also
the parameter must be right next to the command, spaces will cause
invalid input. Example M1234 will display a byte of memory at 1234,
while M 1234 will display memory at 9123.

- 1000 to 1FFF - optional roms or ram (expect roms)
- 2000 to 23FF - standard ram

MMD-1
*****
It appears that you enter an 3 digit octal number and then hit a function key.
H - puts the number in the H register
L - puts the number in the L register
S - puts the number into memory pointed to by HL and then increments HL.
G - Loads the program counter with the contents of HL
1) There is a 'working byte' which you can enter using the octal digits
(just press them in order), and which is displayed on the port 2 LEDs
when KEX is running.
2) 'R' is a hardware reset
3) 'H' and 'L' are used to load the address (high and low parts, and it
really is the HL register of the 8080). So to enter a particular address,
you type in the high half (in octal), press H. Then type in the low half
and press L. The address is displayed on the port 0 and port 1 LEDs when
KEX is running.
4) 'S' is 'Step' or 'Store'. It stores the working byte at the current
address (in HL), and then increments the address. It's used to enter
bytes into memory
5) 'G' is 'go'. It loads the 8080 PC with the address in HL, and thus
executes a program at that address.
OK, this is what I would try.
1) Press 'R' to reset the 8080 and start KEX running.
2) Type 004 H 000 L to load the start address of your program. The bytes
should appear on the rightmost 8 LEDs as you enter them and should then
also appear on the left and middle sets of LEDs when you press H and L.
3) Enter the program
076 S 123 S 323 S 000 S 166S
As you type each byte it should appear on the rightmost LEDs. When you
press S, the address on the rest of the LEDs should increment by 1.
4) Re-enter the start address
004 H 000 L
5) Press G to run the program. The left most LEDs should change to
.*.*..** (. = off, * = on), I think. The keys will then do nothing (as
the CPU is halted) until you press R again to re-run KEX.
When is keyboard LINE3 scanned? it isn't - it's a reset button.

Commands:
All commands consist of 3 uppercase letters. If further info is required
then a * prompt is printed on a new line, where you will enter the data.
All numbers are OCTAL (3/6 digits with leading zeros). Since a teletypewriter
is being used, there is no cursor. Do NOT press Enter except after these
commands, otherwise things get confusing.
LOC - set current location pointer (the CLP)
DLP - display CLP
DPS - dump symbolic
LDO - load octal
DPO - dump octal
LBF - load BNPF format
DBF - dump BNPF format
EDT - enter Edit Mode
XQT - initiate program execution
CPY - copy routine
TRN - translate routine
SBP - set breakpoint
CBP - clear breakpoint
PRG - program PROM
Pressing Ctrl-A will escape back to the monitor. You will see 8 dashes.
Commands in the Edit Mode:
When you enter the Edit Mode it displays the CLP followed by a slash.
nnn - enter a new value into this memory location and increment the CLP
` (tic) - decrement CLP
@ - same as XQT
R - return to monitor
*nnnnnn - change CLP to this value
space - display current contents of memory
While in 'space' mode, press a letter to increment CLP, or shift-delete
(underscore character) followed by a new byte for this location.

THE KEYBOARD
- All commands must be in uppercase - lowercase will produce errors.
- There are 5 special keys which do crude editing functions. These are in
the range 0x61 to 0x75. Kana characters occupy the range 0xa0 to 0xff.
Graphics characters are found in 0x00 to 0x1f, and 0x80 to 0x9f.
- Editing characters (hold down shift to get them):
a - shiftlock (toggle). You can then enter any lowercase character.
c - clear screen and home cursor
d - insert
f - vertical tab (cursor up) You can scroll backwards with this,
and you can reuse old input lines.
u - cursor right
- There are switches on the right-hand side which are connected directly
to one of the PIAs. The switches (not emulated):
s2 - ?unknown
s3 - ?unknown but must be high for the keyboard to function
s4 - cassette motor on/off
s5 - ?unknown
- There is also switch s1 which it is not known what it connects to.
- Please note: The Takeda 80-column monitor expects the enter key to be the
line feed key. This is the numpad-enter in our emulation. Strangely, the
standard monitor, and Basic, will also respond to this key.
- The keyboard has a "English" key on the left, and a "Japan" key on the
right. Pressing the appropriate key toggles the input language mode.
Internally, this turns the Kana bit off/on. On our keyboard, the ALT key
toggles between English and Kana.
