• Use an Arduino and an assembler to enable faster, more complex programming.
• Expand control lines without additional ROMs, using 74LS138 decoders.
• Add a stack pointer and stack to support subroutines with 74LS193 counters.
• Bonus: Enable B register output and add a Schmitt trigger to clean up your clock signal.

Parts List

• 2x 74LS138 (Datasheet, Jameco) which are decoders used to expand the control lines. You can reuse one from the step counter if you don't mind reading binary numbers vs. an LED for each step.
• 1x 74LS04 (Datasheet, Jameco) which is an inverter to help expand the control lines.
• 2x 74LS193 (Datasheet, Jameco) which is a 4-bit up/down counter used to create the stack pointer.
• 1x 74LS245 (Datasheet, Jameco) which is a bus transceiver. You may have a spare one if you did my previous build.
• 1x 74LS00 (Datasheet, Jameco) which is a NAND gate to control the stack pointer.
• 8x Green LED, 1x Yellow LED, 4x Blue LEDs, 13x 220 Ohm resistors to display the stack pointer (green), the stack address (yellow), and the additional control lines (blue).

1. Arduino Mega 2560 (Amazon) to create the programmer.
2. Ribbon Jumper Cables (Amazon) to connect the Arduino to the breadboard.
3. TL866 II Plus EEPROM Programmer (Amazon) to program the ROM.

Step 1: Program with an Arduino and Assembler (Image 1, Image 2)

1. This is optional, but I rewired all the DIP switches to have ground on one side, rather than alternating sides like Ben's build. This just makes it easier to route wires.
2. Wire the 8 address lines from the DIP switch, connecting the side opposite to ground (the one going to the chips) to a convenient point on the board. I put them on the far left, next to the address LEDs and above the write button circuit.
3. Wire the 8 data lines from the DIP switch, connecting the side opposite to ground (the one going to the chips) directly below the address lines. Make sure they're separated by the gutter so they're not connected.
4. Wire a line from the write button to your input area. You want to connect the side of the button that's not connected to ground (the one going to the chip).

1. Create arrays for your data and address lines. For example: const char ADDRESS_LINES[] = {39, 41, 43, 45, 47, 49, 51, 53};. Create your write line with #define RAM_WRITE 3.
2. Create functions to enable and disable your address and data lines. You want to enable them before writing. Make sure to disable them afterward so that you can still manually program using DIP switches without disconnecting the Arduino. The code looks like this (just change INPUT to OUTPUT accordingly): for(int n = 0; n < 8; n += 1) { pinMode(ADDRESS_LINES[n], OUTPUT); }
3. Create a function to write to an address. It'll look like void writeData(byte writeAddress, byte writeData) and basically use two loops, one for address and one for data, followed by toggling the write.
4. Create a char array that contains your program and data. You can use #define to create opcodes like #define LDA 0x01.
5. In your main function, loop through the program array and send it through writeData.

1. If you're on Windows, you can use the pre-built binaries. Otherwise, you'll need to install Rust and compile via cargo build.
2. Create a file called 8bit.cpu and define your CPU instructions (source code). For example, LDA would be lda {address} -> 0x01 @ address[7:0]. What's cool is you can also now create the instruction's immediate variant instead of having to call it LDI: lda #{value} -> 0x05 @ value[7:0].
3. You can now write assembly by adding #include "8bit.cpu" to the top of your code. There's a lot of neat features so make sure to read the documentation!
4. Once you've written some assembly, you can generate the machine code using ./customasm yourprogram.s -f hexc -p. This prints out a char array just like our Arduino program used!
5. Copy the char array into your Arduino program and send it to your CPU.

Step 2: Expand the Control Lines (Image)

1. Place the two 74LS138 decoders on the far right side of the breadboard with the ROMs. Connect them to power and ground.
2. You'll likely run out of inverters, so place a 74LS04 on the breadboard above your decoders. Connect it to power and ground.
3. Carefully take your inputs (MI, RI, II, AI, BI, J) and wire them to the outputs of the left 74LS138. Do not wire anything to O0 because that's activated by 000 which won't work for us!
4. Carefully take your outputs (RO, CO, AO, EO) and wire them to the outputs of the right 74LS138. Remember, do not wire anything to O0!
5. Now, the 74LS138 outputs are active low, but the ROM outputs were active high. This means you need to swap the wiring on all your existing 74LS04 inverters for the LEDs and control lines to work. Make sure you track which control lines are supposed to be active high vs. active low!
6. Wire E3 to power and E2 to ground. Connect the E1 on both 138s together, then connect it to the same line as OE on your ROMs. This will ensure that the outputs are disabled when you're in program mode. You can actually take off the 1k pull-up resistors from the previous tutorial at this stage, because the 138s actively drive the lines going to the 74LS04 inverters rather than floating like the ROMs.

1. Connect A0-A2 of the left 74LS138 to the left ROM's A0-A2.
2. Connect A0-A2 of the right 74LS138 to the right ROM's A0-A2.
3. Distribute the rest of the control signals across the two ROMs.

Step 3: Add a Stack (Image 1, Image 2)

1. Place a 74LS00 NAND gate, 74LS245 transceiver, and two 74LS193 counters in a row next to your output register. Wire up power and ground.
2. Wire the the Carry output of the right 193 to the Count Up input of the left 193. Do the same for the Borrow output and Count Down input.
3. Connect the Clear input between the two 193s and with an active high reset line. The B register has one you can use on its 74LS173s.
4. Connect the Load input between the two 193s and to a new active low control line called SI on your 74LS138 decoder.
5. Connect the QA-QD outputs of the lower counter to A8-A5 and the upper counter to A4-A1. Pay special attention because the output are in a weird order (BACD) and you want to make sure the lower A is connected to A8 and the upper A is connected to A4.
6. Connect the A-D inputs of the lower counter to B8-B5 and the upper counter to B4-B1. Again, the inputs are in a weird order and on both sides of the chip so pay special attention.
7. Connect the B1-B8 outputs of the 74LS245 transceiver to the bus.
8. On the 74LS245 transceiver, connect DIR to power (high) and connect OE to a new active low control line called SO on your 74LS138 decoder.
9. Add 8 LEDs and resistors to the lower part of the 74LS245 transceiver (A1-A8) so you can see what's going on with the stack pointer.

1. Take the clock from the 74LS08 AND gate and make it an input into two different NAND gates on the 74LS00.
2. Take the output from one NAND gate and wire it to the Count Up input on the lower 74LS193 counter. Take the other output and wire it to the Count Down input.
3. Wire up a new active high control line called SP from your ROM to the NAND gate going into Count Up.
4. Wire up a new active high control line called SM from your ROM to the NAND gate going into Count Down.

1. Wire up an active high line called SA from the 28C16 ROM to A8 on the Cypress CY7C199 RAM.
2. Add an LED and resistor so you can see when the stack is active.

• Empty vs. Full Stack: In our design, the stack pointer points to the next empty slot in memory, just like on the 6502. This is called an "empty stack" convention. ARM processors use a "full stack" convention where the stack points to the last filled slot.
• Ascending vs. Descending Stack: In our design, the stack pointer increases when you add something and decreases when you remove something. This is an "ascending stack" convention. Most processors use a "descending stack", so we're bucking the trend here.

1. Define all your new control lines, such as #define SI 0x0700 and #define SO 0x0005.
2. Create two new instructions: PSH (1011) and POP (1100).
3. PSH starts the same as any other for the first two steps: MI|CO and RO|II|CE. The next step is to put the contents of the stack pointer into the address register via MI|SO|SA. Recall that SA is the special control line that tells the memory to access the $01XX bank rather than $00XX.
4. We then take the contents of AO and write it into the RAM. We can also increment the stack pointer at this stage. All of this is done via: AO|RI|SP|SA, followed by TR.
5. POP is pretty similar. Start off with MI|CO and RO|II|CE. We then need to take a cycle and decrement the stack pointer with SM. Like with PSH, we then set the address register with MI|SO|SA.
6. We now just need to output the RAM into our A register with RO|AI|SA and then end the instruction with TR.
7. Updating the assembler is easy since neither instruction has operands. For example, push is just psh -> 0x0B.

Step 4: Add Subroutine Instructions (Image)

1. Copy all the #define, global const arrays (don't forget to expand them from 16 to 32), and void initUCode(). Add #include and #include to the top.
2. In your traditional int main (void) C function, after initializing with initUCode(), make two arrays: char ucode_upper[2048] and char ucode_lower[2048].
3. Take your existing loop code that loops through all addresses: for (int address = 0; address < 2048; address++).
4. Modify instruction to be 5-bit with int instruction = (address & 0b00011111000) >> 3;.
5. When writing, just write to the arrays like so: ucode_lower[address] = ucode[flags][instruction][step]; and ucode_upper[address] = ucode[flags][instruction][step] >> 8;.
6. Open a new file with FILE *f = fopen("rom_upper.hex", "wb");, write to it with fwrite(ucode_upper, sizeof(char), sizeof(ucode_upper), f); and close it with fclose(f);. Repeat this with the lower ROM too.
7. Compile your code using gcc (you can use any C compiler), like so: gcc -Wall makerom.c -o makerom.

1. For jsr, the first three steps are the same as psh: MI|CO, RO|II|CE, MI|SO|SA.
2. On the next step, instead of AO we use CO to save the program counter to the stack: CO|RI|SP|SA.
3. We then essentially read the 2nd byte to do a jump and terminate: MI|CO, RO|J.
4. For rts, the first four steps are the same as pop: MI|CO, RO|II|CE, SM, MI|SO|SA.
5. On the next step, instead of AI we use J to load the program counter with the contents in stack: RO|J|SA.
6. We're not done! If we just left this as-is, we'd jump to the 2nd byte of jsr which is not an opcode, but a memory address. All hell would break loose! We need to add a CE step to increment the program counter and then terminate.

Conclusion

1. Interrupts. Interrupts are just special subroutines triggered by an external line. You can make one similar to how Ben did conditional jumps. The only added complexity is the need to load/save the flags register since an interrupt can happen at any time and you don't want to destroy the state. Given this would take more than 8 steps, you'd also need to add another line for the step counter (see below).
2. ROM expansion. At this point, address lines on the ROM are getting tight which limits any expansion possibilities. With the new approach to ROM programming, it's trivial to switch out the 28C16 for the 28C256 that Ben uses in the 6502. These give you 4 additional address lines for flags/interrupts, opcodes, and steps.
3. LCD output. At this point, adding a 16x2 character LCD like Ben uses in the 6502 is very possible.
4. Segment/bank register. It's essentially a 2nd memory address register that lets you access 256-byte segments/banks of RAM using bank switching. This lets you take full advantage of the 32K of RAM in the Cypress chip.
5. Fast increment instructions. Add these to registers by replacing 74LS173s with 74LS193s, allowing you to more quickly increment without going through the ALU. This is used to speed up loops and array operations.

3. What we mean by fairness

• Individual Fairness – Give similar predictions to similar individuals.
• Group Fairness – Treat different groups equally.
• Subgroup Fairness – Subgroup fairness intends to obtain the best properties of the group and individual notions of fairness.

• Allocation harms. These harms can occur when AI systems extend or withhold opportunities, resources, or information. Some of the key applications are in hiring, school admissions, and lending.
• Quality-of-service harms. Quality of service refers to whether a system works as well for one person as it does for another, even if no opportunities, resources, or information are extended or withheld.
