I expected to deliver the first serie of assembled device two months ago, but thinking about future options for the device, I realized that some small adjustments were required. 
The decision to update the design and delay (again) the release was not easy to take, but I can't deliver a product knowing it will need some changes, especially for a fully assembled device. 
I will send a technical note to all owners of kits shipped before april 2012 to let them know how to update their device.

As I don't given news for a while, here is what was done:

SmartportVHD:
- updated design to be ready for 5.25 floppy drive remapping and emulation (work in progress)
- updated design to support the SmartportRTC module
- added internal connectors for future modules
- compatibility test with DuoDisk passed on the Apple IIe, failed on the Apple IIgs (the IIgs disable all smartport residents if a Duodisk is detected)

SmartportRTC module:
- real time clock for any Apple II compatible with the SmartportVHD
- SmartportRTC driver replacing the original Prodos 8 clock driver
- files are time stamped transparently
- date and time is available for all applications based on Prodos 8 date and time

SmartportVHD Manager:
- allow easy management of virtual devices directly from the Apple II
- select the disk images to be presented to the Apple II and how they are accessed
- support for the SmartportRTC to adjust date and time
- support for the SmartportRTC driver to replace Prodos 8 clock driver
- developped using Plasma from David Schmenk 


Another factor of the delay, is the time required to achieve a fully assembled device.
I expected to get unmolded parts directly usables with small tooling overhead...and I heavilly underestimated the task, as you can see here after...

Total assembly time:
	- 7 hours 10 minutes...

...plus 15 minutes to package the thing ready to ship.

I wanted a cheap solution, and a nice product...I think I reached both goals but as I can't offer so much of my time, I have to increase the price of the product up to 75 euros for the assembled device.
I think it's still a very good price for such a product, especially considering the time spent, but I could anderstand the disapointment of requesters.
I know that some requesters are only concerned by features, not design, so I will check for an enclosure from the market to provide a cheaper solution.
