Since we cannot get rid of it, and it's not really being used for anything else, any chance the 256KB WCS could be used for some of the kickstart? Seems like a few of us are using our A1000's for the Vampire, and an extra 1/4 MB isn't a lot, but it's something :)

Vampire has his own embedded 1MB flash-kickstart and 128MB FastRAM
 
For A1000, GOLD3 will be great as it will bring 4MB of ChipRAM plus AGA to it. This will be the ULTIMATE Amiga :-)

So that flash-kickstart uses no RAM?

That is what I am waiting for especially since I just fried my Aca500 plus. Jens warned me.

Most astonishing "Vampire side effect" might be v4 accelerated A1000. Beside being original, and rushed in some aspects, one of most beautiful Amigas ever.

It uses the fast RAM on the Vampire making ROM access very fast.

Ehh, I'd rather just have the flash memory mapped. A single QSPI flash can easily do 300MB/s. Not exactly "slow".

That's probably a peak a data transfer rate. For a ROM you aren't just transferring data, you are following code that needs random access to different areas of the ROM with low latency. AFAIK The ROM image is held in the serial configuration device (possibly in a compressed form) that is used to configure the FPGA at power on. The ROM image must be copied to RAM before it can be executed to bootstrap the Amiga.
