Quick question,
Assuming I were to pick up an accelerator for my C-LAB Falcon, will this essentially sidestep the whole 16-bit wide external data bus that is a problem with the built-in stock 68030 on the Falcon? I've never really understood entirely how the processor direct connection works in this case. Can anyone shed some light here?
External bus when using a CT60

Re: External bus when using a CT60
The 68060 will access the faster TT-RAM on the accelerator board using a full 32bit bus. Any access to ST-RAM on the Falcon board will still be via the 16bit bus. Only the 68060 can access the TT-RAM.

Nicely shown here (thick black lines = data bus):
To skip also the video part, you need a SuperVidel or CTPCI. That way only a few remaining components (sound dma and the blitter) will share the slow 16-bit data bus.

That all makes sense. Thanks!
I've considered leaving my system bone stock, but I can definitely see the utility in something like a CT60.

Re: External bus when using a CT60
The CT60 is an awesome upgrade as it's easy to switch back and forth between the stock 030 and the CT60. The only caveat is that it's close to impossible to source the 68060 nowadays.

If you wait a little bit, Badwolf is close to finalising a 50Mhz 030 Accelerator with full 32bit fastram design. He won't be producing it, he is releasing as open source - so before long you may find it quite easy to obtain one of these which would be a vast improvement for a stock Falcon.

I can't seem to find this project page.
