Hi,

Just purchased ADP-054 from your ebay shop and a couple of 28F102

I can blank check ok, write and read OK, BUT not erase.
Verify works too.

If I erase I got OK, but then blank check fails and if I read, I got tons of data from it.

Verify fails after using erase, so something is getting cleared out.
If I try to write again, the verify phase fails.

I do get correct ID of 28F102 if checking.

First I hade software 6.13 but now I installed 6.17 and latest USB driver 2.0

hardware is FW 1.30
I am not using external power.

I am using lower right corner PLCC44 soxket, as 27c1024
J1 is at 1-2
J5 U4

Any help or advice is appreciated

You do not need the external power.

Try to slower speed a step and see if it works.
