Got a used Arduino MO PRO can not seem to get it working

Using the Web editor and have all installs correct. The board and port are selected/available correctly. What follows is the message I get:

The Zero has a similar issue reported. Read this post:

Regrettably, I do not have any MO experience, but looks similar to the Zero issue.

Oh, and welcome to the forum!


Thank you,
I really have no idea what this unit has been through. I pulled it off an old prototype someone was done with at work. I have no idea where to find the people who worked with it originally. I just hope it's not broken in some way. I wouldn't be in any trouble I just wouldn't be able to learn from it anymore. There are two of them and both have the same issue. I have tried to use the non web version of arduino coding too.

Take an old battery transistor AM radio, tune it down in the 550-600KHz range with no station. Place the radio antenna near the Arduino, power up the Arduino, press reset. You should "hear" the Arduino processing. If dead, the AM radio will not receive the "hash" RF created by the digital circuits.

Thank you again, I'll have to find one somewhere. Might go by a pawn shop. Any ideas where I could get one from somewhere else?

The first option got it to work. Thank you again very much. I still plan to get that radio though, as I think that trick might help me later with some other old bits of circuitry and PCBs I have found with GPUs and microcontrollers on them.

It is a neat trick. Old transistor radios can often be found at yard sales, on eBay, or parents/family attics, basements, closets! You can even build one using a ferrite rod antenna and a few transistors. Even Amazon & WalMart have A.M. radio kits, although I think they are a weebit too expensive:

In the "old" days of the early '70's, You could get to know the "music" produced by your microcomputer as it would go through the various stages of boot-up to DOS; each I/O card had a ROM and unique sound as did the disk controller.

I just looked on eBay and found several "untested" units under $10, etc.
Unfortunately, there is an insane belief that old == rare == antique and that a $10 old transistor radio is worth hundreds of dollars; it is not. Beware of scams.

In addition to the A.M. radio kit, you could just build your own from a few scrap components:

The key feature is a ferrite inductor and variable capacitor so you can achieve a high Q resonant circuit and the ability to tune-out interference from home electronics and lighting: fluorescent lights being a really ugly noise maker.
