Hello to all HP-71b enthusiasts,
I have got a defective CMT 64kB front port RAM module; the calculator doesn't recognize it, just behaves as if nothing is plugged in. We opened it and cleaned the contacts, but that didn't help.
Now I hope that there are skilled people who might see a chance to revive it ...
It is for free to a good new home, just for the actual shipping charges.

Hi Michael,

I'll take a look at it. Do you also have the battery?

Meanwhile the module has found a new home at a highly respected celebrity of our community.
