Is an Orange Legacy module writable??

I think if you short 2 pads inside together you can write to them

No, the orange modules are not writable. Only the black ones are designed for read and write.  GunRunner John figured out how to make the blue modules writable so I assume the orange ones are the same.  He had a thread on how to do it.  It involved taking the module apart and moving one of the components on the board.  VERY TINY soldering in order to change it. I tried it on blue ones I had and I got it to work.  I also have a black module as well.

The orange module doesn't have the same chips as the blue and black, and thus is not capable of being made into a "black" module.  The blue ones are easily converted to black modules, see Free Black Modules for Legacy for details on how to do the conversion.

The Orange modules can be modified to write them. I would think it would be a good experiment to see if you could use the LSU program to make the module for 1 or more engines.  I don't think you could store the entire roster in one, but it seems a single or a few Engine records would be OK.

I figured with only half the capacity that the LSU would choke on it when it tried to write. I also didn't have any orange modules that I wanted to sacrifice. 

Blue modules are a dime a dozen once you've used them for an update, and I've had no problem with those.

Thanks for the info! Now I don't feel so bad if I just toss it out.

Well, you could give it a try.  If you want to know if you can write them, you can send it to me and I'll test it.

I am curious what the LSU would do when it found a half-sized module.

John,

PM your address and I'll just drop it in the mail to you.

LSU has 2 modes:

1) making a module for O/S updates (cab and base)

2) making Engine Modules (Orange style Modules). 

So clearly the LSU program is designed to work with all module sizes as it can write Blue and Orange module equivalents.

Of course the generally available Black modules are writable, which are the higher capacity modules, to make sure any module creation process can work.

Thanks Jon, I thought it might be unhappy if it saw a "small" writable module.  Sounds like it wouldn't mind at all.  I'll take a "whack" at Jeff's module and see what results I get.

Thanks GRJ

John, Can anything be done with an orange module that will not read?  It came that way with the engine.  

Hopefully that's what John's experiment will tell us!

If it's really just unprogrammed, swapping the internal jumper and then creating an engine module would give you what should have been on it from the factory.  You will have to make sure you enter all the stuff like name and cab # so it all gets programmed.  I'll post back when I do the experiment and let you know what happens.

Geez John with all that money you can't spring for an orange module.  G

How do you think I got all that money?

GGG,

   Well I know where John got some of that money, from installing ERR in one of my Tin Plate Engines and Tender, can't wait for Christmas to test her out.  John makes his money the old fashion way, he earns it with his exceptional work.

No joy on the orange module.  I moved the jumper, but it's not recognized when I attempt to write a single or multi-engine module.  Apparently they need them to be a full dual-chip module to recognize that it's writable.
