Andy has asked that this thread be closed and further questions handled by E-mail.
Either I missed that part of the post, or he posted that while I was typing my earlier response, so my post bumped this to two pages and people may have missed that. I'll try to answer the latest questions:
cheezeflap: I assume you mean the Winipac IPD software. I don't think it's available yet. Andy said it would be shipping with boards next week, so I would guess it will be available from
www.ultimarc.com shortly thereafter. (It's possible it will only be available with an I-PAC purchase, but I doubt it. (Hope not!).)
Retroborg: I think it's just the internals that are changing and not the mounting dimensions, but I can't say for sure.
