Yes its probably a MS, just not a PNP model. Either MS1 or maybe an MS1 with an upgraded MS2 daughter board. The small connector is the serial port to communicate with it, then you'd want to get a DB37 wiring harness from DIY autotune, and a DIYBOB. Solder the two together appropriately, and it would be PNP? Not sure it's worth the money or effort.
Indeed, that appears outwardly to be very old MS1 (or MS2) with probably a rev 2.2 or 3.0 circuit board.
If you remove the screws on one side and slide the top off so that we can see the circuit board underneath, we'll be able to tell you more.
Do you know what car it was previously installed in?
ALL Megasquirts of this generation required some internal modifications to function in a Miata. Specifically, for two-channel ignition output and two-channel (crank and cam) input. And the stock circuits for the trigger inputs don't work very well with the type of sensors used in the Miata, so they pretty much need to be replaced in order to work reliablly.
Since you have an NB, you'll also need to deal with the fact that the alternator is controlled by the ECU. Fortunately, you don't have VVT, but you will need to deal with the VICS system, assuming you haven't removed it.
Do you care whether your air conditioning works? That's another mod.
Long story short: it takes a lot of work to get these older Megasquirts to work on an NB. There's a good reason we all stopped using them years ago when the MS3 became available. The only downside to the MS3, of course, being that Bruce Alan Bowling and Albert Carlos Grippo are both serial child-rapists who worship Satan and refuse to publish the schematics for it.
If you search back through the archives here, you'll find dozens of different threads, each one detailing a different fix needed to make the old MSes work on these cars.

okay thank you, what would u recommend for the NB that would be cheap?

Stock.
But seriously, I don't know anything about your engine, your power goals, your personal level of experience with electronics, or your definition of "cheap."
Check out speedyefi, that's the cheapest standalone I'd recommend anyone running.
Based on how much the owner of the company is a massive dong on social media, i'd never buy a speedy for that reason alone. I'd try a RUSefi before I would give speedy money, but that's just me.
I'd like to point out SpeedyEFI isn't even listed as a vendor on the Speeduino website. I don't know what the social media drama is all about but there are other options for purchasing a speeduino.

Not much, just carrying on with unprofessional **** like this, shitting on oither people's products as being subpar when his own product has had some reliability problems, and hijacking someone else's for sale thread and generally lowering the room's collective IQ to room temperature.
I don't appear to have caps of the time he called his own customers "idiots" when they ship the ECU with a less functional firmware but then need to deal with said customers to help them install said firmware
Yup that's plenty to show people they should stay away from SpeedyEFI. I just think it's important to point out SpeedyEFI is not Speeduino. They sell Speeduino based ecu's but AFAIK have contributed nothing to the project and are not listed as a speeduino vendor. It looks like they're taking advantage of an open source project and destroying the entire project's reputation.
Some of the vendors on the link I gave provide PNP Miata options. For those willing to put in a little more work and build their own harness all of those vendors have options that can be made to work on any Miata. I've personally ordered from wtmtronics with no issues.
Help! What is this, Guy claimed it to be megasquirt and I知 broke so I bought it
