It could give a hint whether you have a cpu which can go as high as 1MHz - if not, there may be other issues you could encounter (and the choice might be to have 2 71B on hand as opposed to one.)

The model I have is 1BBB with the single screw in the battery compartment. There is a picture of the insides https://www.facebook.com/photo/?fbid=937...1359683085

As for having two 71's, are you offering one of your "extra's" as the price that an unemployed engineer can afford Also, this 71 has 128K of internal memory in addition to being sped up.

And the HP-IL works with the speed up.
