Having just joined this listserv, I hope I am not abusing proper protocol by
forwarding my own usenet post originally posted to asking for more information about a recently
acquired SP-600.  I figure this forum must be a good source for answers to
my questions, and that not all here read the usenet RRAE I posted to earlier.

Thanks in advance for any help.  And, if you want to reply to my email, I
would be happy to summarize all info received and repost for the group, if
there is interest.
