Can anyone give me a site to get detailed information on 8085 microprocessor???

Question

I cdnt find any useful websites on this topic. can anyone tell me the sites that can give me detailed information on 8085 esp its architecture and instruction set????

Answer 1

here is the data sheet

I used to have a paper back book that dealt with the software, perhaps you can find that somewhere.

Search google for "8085 software" and you may find something.

Answer 2

I think the other guy is correct in that you would program using the 8080 instruction set. But you might consider looking for software that ran on the 8085 for hints as to its capabilities.

For example, the Xerox 860 word processor machine used the 8085 processor. These systems had a WYSIWYG black-text-on-white-screen, full-page display, and used Mac-style graphical menus operated with a touchpad, very advanced for 1979 computers, thanks to Xerox PARC. And while 8085s, like 8080s, were limited to a 64K address space, the Xerox 860 had 128K and could switch between one 64K bank and another one. One held program code, the other held data. A version of BASIC and a nice terminal emulator program were also available.

Also note that the 8085 as used in the 860 ran at 3 MHz, but there was also an 8085-2 that ran at a blazing 5 MHz.

Answer 3

i am sure you know that the 8085 is compatible with the assembly code for the 8080. it think the only difference is that the 8085 uses a charge pump to create the 12V needed to operate the processor core from a 5v supply. using the 8080 manuals for programming should be ok as long as you follow the hardware guide for the 8085. i gave a link for an assembler. i have never used it so i cant say if it is good, but it is free. ps alldatasheets.com is a great source for hardware datasheets. if you are building a motherboard, you will need to visit it at least once. unfortunately their scans are not always of the highest quality.
