Thanks, Diego. I already told you in the email, but for the benefit of others, here is what I did:
I used HEXEDIT to change h'4100 contents to h'003. Within a second--I didn't even have to leave HEXEDIT--NONEXISTENT started flashing. I did NOT remove the battery this time--instead, I executed the ENTER-double ON manoeuvre and found myself with a normal display. I did NOT turn off the calculator--I simply executed CLRAM for 11 down to 8, and, voilà, on turning the calc on and off I am able to point myself to RAM chip 3 by changing h'4100 to any of the configurations that do so.
Of course, I lost everything, such as it was, in the 4 pages of HEPAX RAM in chip 3, but considering that I believed I had physically damaged the memory, this is a small inconvenience. I have been able to restore my desired ROMs and other files using ClonixConfig and mass storage routines with HP-IL and PIL-Box.
Thanks for the reply. I am learning a lot and sorting out things on my own.
Les
