Probably you've already got this somewhere, but if this seems like it might be not otherwise available I will have to try to image it. Let me know.
No harm in imaging it, just to be sure.
Well yes, but I could save myself considerable effort if someone else has already done so!

These are the Atom Econet ROM versions that I'm aware of:
http://mdfs.net/System/ROMs/AcornMOS/Atom/Econet/

So something that was NFS 3.60 for the Atom would be worth archiving.

Thanks for that pointer.

So it's probably 3.50 that you've already got, but because of my careless handwriting 30 years ago I now need to download it and find out!

Even if claims to be 3.50, it's worth checking the binary is identical.

Is the CRC on the bottom 9D85?

That's the CRC of AtomEco148, available here:

It looks like a D but in can also be a 0 or O. I can't see it clearly.

Worth trying to take an image then - it's possible it's a version that's not been seen before.

(Also, maybe the contents don't match even the CRC?)

Ok, a rare econet rom then ? Unfortunately I do not have an eprom programmer that can read 2532 eprom's, perhaps I can send it to Roland , if he wants to do that of course. I don't need it back.

You can check the CRC if the rom is installed in an Atom or System.

Worth doing I think.

:shock:

How? And where did you order a new one? I recently bought one on Ali but that didn't work. I contacted the seller and he send me a new one. And that didn't work either :( My financial loss was €0.91 :lol:
