Yes the Dallas chip is on the SCSI card. I tried an external battery hack as well as a replacement / equivalent -Dallas 12887, the message : real time clock not initialized is the same in both cases, and I am unable to manually reset or enter information. I am unable to access the hard drive, and therefore unable to boot. On the first quarter of 2018 Ian Eure, encountered an RTC issue TECHTOOL list :DS1287 repair Tony i recall you had also mentioned and shared a post on an RTC issue…I can’t seem to find it any more. None of these posts may have captured my issue in entirety. With regards to the NVRAM issue: I wanted to enquire whether the NVRAM U36 and U26 EPROM are up to date? I have version 1 in both cases and so I shared Information on the same in my previous post. I would also inquire if the is a relation to the problem I am facing. As always I appreciate any support. -- Regards, Kevit Desai Tel: Mobile: +254 722 517067 _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
