No wonder - just a plain 27512 or so. No, this DN4500 just made this morning it's final exit, to be reborn as coke can...

What I meant, of course, that some HP425e owner should try to extract the PROM in such a way (you must switch the PROM temporarily into Domain mode, of course), and perhaps send it to you...
I'd assume that the PROM starts at 0 (beacuse of the reset/nmi and trap vectors).
