quick help tunerpro chip read function???

[Blazer3664]

Long version........

Trying to familiarize myself with the new equipment.
So I got my AutoProm all hooked up inside where its WARM (freezing out by the way), tunerpro rt going.
Pulled the eprom out of a 7747 I have sitting here, thinking I should start by trying to read a stock chip. Put it in the AutoProm as stated on the quick start.
Tools
>hardware utilities
>moates prom I/O
>supported chip set as "2732A (read only)
>read chip
and I get

"reading device into buffer..."
"ERROR: Memory range and/or address outside selected eprom size"


now if I do the same but chose any of the following
29C256
29F040
27SF512

I get a progress bar and then
"PROM I/O succeeded"

?????Pretty sure thats not right?????

Also pretty sure its my oops, not the equipment.
So what am I doing wrong here?

Short version......
HELP!!

Thans in advance,
Jim
