[Techtoolslist] Rom needed for Data I/O 303A-011A V01 Module

[Matthew Rossiter]

Well I found someone with a V01 module and he confirmed that it only has 
3 eproms so my module is complete.  I'll make a backup of them.  From 
the docs I've read, V01 is the one module that is difficult to upgrade 
because you need to replace the daughter card.  V2-V4 is a simple 
resistor change along with the software.  The versions after that don't 
require any hardware change as far as I know.  I'll be getting a V14 
module fairly soon, which means this one is going on ebay unless someone 
here is interested in it.

Thanks for the help!
