I have xe130 as soon as I turn the computer it goes right into
the ram memory test the top 2 bars check out ok and the first
ram square is good then 3 bad 1 good 3 bad 1 good 7 bad 1
+1 good 10 bad 1 good 3 bad 1 good 2 bad and then it only
continues the ram test skipping the bad squares I cannot get 
it out of the ram test. has any one run to this problem?
any advise at this time will greatly appreciated.
thank you in advance.

It certainly sounds to me like you've had some RAM chips go bad.  The one
time my 130XE failed a similar pattern appeared.  First, I found I couldn't
run anything except for what I knew were 8K cartridges (Star Raiders). 
Then I tried out the Memory Test, and indeed, a bunch of the squares were
red, with no particular pattern to them.

If you're adventuresome in hardware hacking you could probably go in and
try swapping/replacing RAM chips, but in my case my solution was to have
the machine fixed by a repair specialist.

See the 8-bit vendors/developers list for shops that do repairs, though the
list doesn't necessarily specify whether a place does repairs.  Two off the
top of my head are Computer Software Services and The Electronic Clinic.

Good luck!
