It works now.

By the way, is there is rom list that still missing on public domain?

As far as I know, there is HP 10 which is a hybrid CPU chip can not use this rom reader.

And also the famous HP95C. Maybe someone own the HP95C could read out the ROM.

Except these two, are there any more? (The domain is limited in classic ,woodstock, spice)

I don't think you'll find the 95C ROM codes as it was never released.

The ROM for the HP10 is embedded in the large IC so can't be read without destruction of the package. I wrote my own version of the code which is in my HP-10 simulator.

cheers
