As a microprocessor, the 8085 was supplanted in price and performance by
the Zilog Z80 quite a few years ago.  In any event, for what you're doing,
you may want to consider a microcomputer such as one of the 8051 family,
which have RAM, I/O, and ROM (if you want) onboard.  Get the MCS-51
family manuals from your local Intel sales office.
