PlayStation Vita Communication Test Boards

Hi Guys,

Just looking for a bit of a pricing discussion and to gauge interest.
Purchased three of these boards that were destined for destruction elsewise for hardware security research and have now shifted project attention elsewhere.

History on these units is as follows:

• Boards used for internal testing, loaded with OK NG software (dolphins) and presumably were sent off to be recycled after internal testing was complete.
• Shipping container ended up in China for recycling (along with other hardware for part extraction and melting).
• Supplier offered these units (3) plus some others (2 to my knowledge) to another private buyer and colleague.
• The rest were destroyed.

I have three units available, but one is potentially spoken for.

They fit into the standard PS Vita and are compatible with other daughterboards. They are in Japanese (obviously) and boot to OK NG with the correct button combo + to recovery menu and will accept retail firmware from a game cartridge or storage media that will install unsuccessfully (due to keys or factory fuse settings, mystery never totally solved).
The "SCEI" chip on the underside of these units is unbranded (no Sony logo, part number, bin number or batch number). They also have a chip revision paint marker. Are marked with original (Renesas) factory details.
They have their individual testing ID's and special board part numbers to identify them as communications test boards.
They will also report a unique 'blank' Vita serial number when queried via USB.

Whilst obviously nice for a niche collector, they have possible unlocked potential for when we know more about working with the system security as a whole.

Any idea what these might be worth to a collector? They are the last of their kind.
