[Techtoolslist] Xeltek Superpro 2000+ repair

[John Robertson]

Anyone using one of these, or has one in a junk drawer? Mine appears to 
have either a bad 29F040AT-90 or 29F080T-90. Machine gets to Write 
Memory OK! 7FFFF, in memory test then craps out saying Verify Memory 
ERROR! 0 0 0

The device programs up to 2MB with no problems, but it gets bad writes 
on 4MB devices Verifies fine though.

My hope is someone else has the sub-memory board (labelled SPABUF) on a 
used/dead machine or has one or more of these TSOP style chips in their 
junk box they would sell and ship to me.

I am going to get a newer Xeltek (600P) but this old timer (2000+) is 
nice to have as a spare in case something goes wrong with its replacement.

Thanks,

John :-#)#
