PIC's are easier to build with than 8085's. No external rom or ram needed.
Some even have built in oscillators but you'll usually want to use a crystal
and a couple of caps for the clock. ( or use a crystal oscillator which is
what I do most of the time ).

Now you'll need to have something to program the PIC with. Plenty of cheap
programmers you can buy or even build.

Now just get a breadboard, your PIC and some LED's. Then learn how to write
the code, assemble or compile it, burn it into the PIC and test it. Start
with blinking an LED. Then move on from there. Only 35 or so instructions if
you want to learn Assembly. Or get one of the cheap commercial or shareware
C compilers. The assemblers are free.

As others have said there are some great beginning PIC books out there.
Mike Predko has one I'd recommend.

Here's a good starting page with lots of PIC stuff on it:

Start with one of the F parts. That's a flash part that you can reprogram
over and over. Like a 16F84A which is the most popular beginners PIC.
