Hello,

I have a HP8720A that is in revision 1.02 and I would like to upgrade it in revision 2.00 or 2.01 in order to get the multimarkers readout.

I'm looking for someone that would have a copy of the content the EPROM from a unit in revision 2.00 or 2.01. Or I'm looking for someone that would have a HP8720A in a revision upper that 2.00 and who could be able to copy its EPROM for me.

EPROM are on sockets and over the fact to help me, it would be interesting to get a backup firmware shared with the community.

Thanks for any help.

Best regards

Fabien, F4CTZ.

  Hi Sebastien,
  As revision 2.00 import a lot of functionalities from HP8720B on HP8720A, do you know if CPU board from HP8720B or EPROM from 8720B could be compatible with a 8720A hardware ?
  Do you already try such a swap of CPU board ?
