data I/O promlink 3.4 vs 6.1 oddity

[Jay West]

I've come across an oddity I can't explain.

I read a prom on the data I/O 29B via promlink version 3.4 and have it write 
the data to a file. The file size is 256 which makes sense for a MMI 6301 I 
think.

I then switch to promlink v6.1, read the same chip, write to data file, and 
the resulting file is 629 or somesuch.

Doing a load file to ram and verifying the device against ram tests 
correctly, in both cases.

I would normally think that perhaps I set the I/O format differently for 
each version of the software, but I didn't. It's (10) binary on each one.

Can anyone offer an alternate explanation that I might look at?
