Re: Newcomer arriving soon...
And here comes today's progress:
A heatsink is fitted to the FPU (now running at 48MHz) and I also plan to install a heatsink/fan on the CPU.
Also soldered pins to the ATW800/2 USB IN port so I can have my USB ports at the back of the machine.
A nice result...
I had to trim the USB connector though.
Here's what it looks with the VME cradle in. The FPU heatsink sits below the ATW800/2 card and the USB connector doesn't interfere with anything.
And the back of the TT with the AT800/2 and its titanium made backplate.
That's all for today !

Re: Newcomer arriving soon...
Where are the ATW800/2 boards available from out of curiosity?
