How were programs that were written in assembly loaded into memory of 8085 processors? Did the processor come with a bootloader with which you could load information into memory? If so, what did the program look like? In my 8085 simulator I press assemble and and load program and it automatically loads my assembly program into memory. How was this magic done in the original 8085?
How were programs written in 8085 assembly dumped into memory

I actually wrote a full blown application (digital diary) for the 8085 in assembly 35 years ago as my final school project. I had an original IBM XT at the school lab with asm85 assembler. I wrote an entire 6K assembly program in that extremely simple editor and assembled it. The PC was connected to an EPROM programmer via the serial port. I ran a command in DOS that copied the 6K obj file the assembler generated to the EPROM programmer RAM. I installed a 8K EPROM chip to the programmer. The programmer had some keys to operate it so I selected Program at base address 0000h. Obviously my assembly program started at that address so everything worked perfectly. I took the programmed EPROM chip and connected it to a socket on a board I created using ORCAD with a 8156 chip for ports and another chip as an address bus latch. That was a minimum system with another small ram chip and an external 5V power supply. I got a perfect score (100) for the project and it worked until a year ago when I found no use for it anymore and threw it to the garbage bin.
