I’ve seen some Intel P4040s on eBay going for $40+. Is that too high?

a later one with an FPO (Like X123456) is uaully closer to $25-30 |
What's an FPO? I'm slowly learning my terminology lol 
Edit: How easy would it be to make a simple system (like blinking an LED) with a P4040 on a breadboard?

| The wiring and componentry would be easy, but you would need a way to deliver the code. Do you have a way of programming a compatible ROM? I think that would be the hard/expensive bit. |

I'm new to all of this. The only thing I ever programmed in my life was Python and C++ last year in 10th grade. I'm thinking about buying a 4004/4040 manual.
I forgot there was code involved. I can't just "plug and play" with a 4040?

Might be a good idea to start with something modern, easy, and cheap... Arduino has a LOT of libraries available. Microcontrollers are the way to go if you want blinky lights and low effort.
Otherwise if you want to simulate hardware and get down into the nitty-gritty, look into FPGAs. More expensive than basic microcontrollers, but used industry-wide. Those are pretty much the current standard of hardware design and prototyping. You could make your own CPU from scratch (not as difficult as you'd think, assuming you keep it simple). Well, you can make an FPGA into anything really.
There are also various processor emulators available if you are looking to do machine code. Start with RISC based processors if you want to play around with basic assembly instructions (ARM is a good choice).

Just curious, would an INS4001 ROM work with a P4040?
MCS-40 set (4040) part numbers for ROM are 4308 and 4316. Not sure if MCS-4's 4001 would be compatible with MCS-40.
