Hi all,
my HP 54200A left me. It dumps lots of &&&&& on the screen, no beep, no keyboard actions, no obvious hardware damage.
I suppose that the contents of the EPROMs have partially disappeared after 23 yrs. Lots of FFs between binary and text code, quite unusual for expensive EPROMs anyway.
Does anybody own a functional 54200A and is willing to read those EPROMs and mail me the content?
Any help is much appreciated.
Thanks,
Andy
