The NVRAM chips used to be designated Mostek MK48T02 etc. These chips
come in various speeds. The newer SGS-Thomson part numbers are
M48T02-200PC1 for the 200ns
M48T02, M48T08-100PC1 for the 100ns M48T08. 200ns is adequate for any
Sun, but often the faster chips are easier to come by, and there is no
harm in buying them. If you have trouble
tracking down a local SGS-Thomson distributor, Mouser electronics sells
the SGS-Thomson Timekeeper chips (telephone: 800.346.6873,
+1.817.483.5712). You can also order from
Mouser on the web at http://www.mouser.com/. The Mouser stock numbers as
of 1995 are slighly different than the usual part numbers and are as
follows:
