Xeltek 2000+ Programmer memory issues

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.

Heck I have a pair of SuperProZs, and a SuperPro2 as backups to the

Thanks,
