Here is the machine code that is running on this machine at start:
mem[0]=0x23; // load register a with following
mem[1]=0x00;
mem[2]=0xa8; // out put a to r0
mem[3]=0x17; // increment a
mem[4]=0xa9; // out put a to r1
mem[5]=0x17; // increment a
mem[6]=0xaa; // out put a to r2
mem[7]=0x17; // increment a
mem[8]=0xab; // out put a to r3
mem[9]=0x17; // increment a
mem[10]=0xac; // out put a to r4
mem[11]=0x17; // increment a
mem[12]=0xad; // out put a to r5
mem[13]=0x17; // increment a
mem[14]=0xae; // out put a to r6
mem[15]=0x17; // increment a
mem[16]=0xaf; // out put a to r7
mem[17]=0x17; // increment a
mem[18]=0x04; // jump to first page with following
mem[19]=0x02;
Note that this is 8048 machine code. Also,
I don't have many commands programmed yet. This is it!
You can certainly fool around with the above commands. You really
do have 64K mem locations to program from the front panel. When this code runs, you can see the program counter start at 0. When you toggle run, it loads up location 1, so the program counter never really has a state of 1. Likewise, when you get to 18 (12 Hex), you never see 19, because of the jump to location 2 on the first page.
