Possible to determine A500 board revision without opening the case?

[Oldsmobile_Mike]

Is there a software tool to determine the board revision of an A500 without opening the case? Or any other possibility?

I think this question has been asked before, and AFAIK no, not with any certainty.  A couple ideas though:  an older model will typically have a red power light (revision 3, 4, or 5), newer model will have a green power light (revision 6 or 8 motherboard).  This is not with 100% certainty, however, since many motherboards and keyboards get swapped around.

Another suggestion would be to check amount of available chip memory - a newer model would be more likely to have 1MB or 2MB.  Again, not 100%.

Am sure others will come along with other tips!

Intact warranty seal. + Saving time when you have to check a large number of machines.

Just what are you getting at here?  How many machines do you have?

Better yet, sprinkle some radioactive Cobalt-60 dust in there and shake it around and then use a Gamma camera to see what it says!

Nah, I'll just get out my hammer.  :hammer:
