[SunRescue] Bad - new NVRAM/TOD??

[Harry Regan]

Steve--

The only machines I've tried this on are IPXes (IPXen? IPices?)...
But I have three to play with so I can demonstrate that the problem
in not unique to a particular machine...

harry, steve...

   were the chips that worked (m48t12-150) used in an ipx
   or ss2? they're the ones I have access to at the
   moment, no ipc's.

   I've actually found an old sun bug report (1055000)
   that mentions the problem specifically on the 4/75
   (ss2) as being a testing bit flipped by the
   manufacturer, and not being reset properly by the
   kick-start routine, and ... no resolution was
   offered...

   I wonder if we used an ipc to initially set the chip,
   whether that would fix the issue?

   Like you, I've tried several commercial sources and
   have gotten the same chips from both - apparently
   sgs/thompson is the buyer/successor to mostek.

   I haven't tried any Dallas Semiconductor chips, mainly
   since the nvram faq said they mostly don't work
   either...

   So I will also try the m48t12-150 - thanks for the
   reply!!
