Vampire 500 V2+ differences over V2 version:
1. Rework on internal layers that will probably enable higher clocks.
2. Modification on headers <->DIL to support much better connectors who will ensure stable connection to the Amiga motherboard
3. Tiny improvements on video-out again regarding internal layers
4. I/O expansion header with support for WiFi module(AP, client mode) (WiFi module drivers not developed yet, but in future maybe they will be:))
5. Logo update
Just to mention Vampire 500 V2+ is 100% compatible with Vampire 500 V2 version.
Sorry for bad pictures, I don't have anything better to take pictures as you probably noticed in past few years.
You don't get Amiga 500 with this or WiFi module, only accelerator card.
Accelerator card should be used on Amiga 500 and 500+.I don't have adapter boards who will enable this card to work on Amiga 1000,2000. You will need to design it on your own. I can't help you with that.
It is recommended to get yourself USB blaster, you can order it from lot of places including E-bay for no more than 3USD.

Apollo-core ported to Vampire provides fastest accelerator there is/was for Amiga.
There is no need to write in detail about this because if you are Amiga fan you already know all about it.
