Of course, the Vampire V2 works VERY nicely inside an Amiga 1000 and solves a lot of its problems. I use the SD-to-Ethernet solution, so all-in I have 3.1.4 ROM (which I bought and flashed), Ethernet, 68060-class accelerator with 128MB RAM (more than enough) and HDMI RTG output. And of course, a 32GB CF slot for my boot drive.
I actually prefer the HDMI separate from the ECS as you get dual display this way, and that's great for debugging. I have an Indivision ECS V2 and you can print my Denise 180 board to fit it nicely in the Amiga 1000's case. This gives me razor sharp VGA from the native chipset and even sharper HDMI for the RTG. And one huge advantage of the Vampire is that graphics memory is CPU local memory and the V2 has a wickedly fast memory controller.
The one thing it DOESN'T do it mate with the A314 -- right now only the Amiga 500 and soon, the Amiga 600 can support that.
