Well, it was a success; You can run the processor without RAM, it requires a lot of register juggling but yes, it does work.

My application just has to monitor serial port data and respond to a certain string, so I really didn't need any temporary storage since the data comes in byte by byte.

I ...

Oh yeah, if I can ever get this sucker into production I will definitely use a PIC, but right now all I've got in my toolchest is the trusty ol' 6502. I'm wiring it up right now, I'll post my results a little bit later tonight.

I'm working on a small, embedded microcontroller and I am trying to minimize the number of chips, so I was wondering if I could just use ROM, i.e. a RAMless machine.

I figure it would work okay as long as I didn't use interrupts or JSR or the stack, what do yall think?

I've gotten 65c02's from them, I don't know if they are refurbs or not. The part # is 43166.

Also, jameco is a great place to get datasheets.

I get mine from www.jameco.com.
