What address does an 8085 start at and what address do the interrupts go to?
At reset, the 8085 starts at location 0000H. The INTR interrupt goes wherever the interrupt opcode says to go. The TRAP interrupt goes to 0024H. The RST5.5, RST6.5, and RST7.5 interrupts go to 002CH, 0034H, and 003CH respectively. The RST X interrupts goto 0000H plus 10H times X, i.e. 0000H, 0008H, 0010H, ..., 0038H.

How do you change time to 12 hours instead of 24 hours?
I am assuming that you mean "how do you change the time from a 24 hour clock to a twelve hour clock." Just subtract 1200 hours from any time over 1200H. 0000H is midnight. 0100H is 1:00 am etc. up to noon. 1200H is Noon. 1300H is 1:00 pm (ie 1300 - 1200 = 100 = 1:00 pm). 1600H would be 4:00 pm (1600 - 1200 = 400 = 4:00 pm). 2200H is 10:00 pm (2200 - 1200 = 1000 = 10:00 pm).
What is physical starting address and ending address of interrupt vector table of 8086?
The 8086 interrupt table is from 0000h to 03FFh for interrupt 0 through interrupt 255. It is common practice to design systems that use only the lower-numbered interrupts and then use the upper part of the interrupt table for code or data.
