Needs to have RTG included just to really annoy people.
And an FPU. Obviously.

As many of you have guessed this is so that Buffee can run in an A1200. I plan to give a limited number of these away free with Buffee purchases once its all confirmed working.

I was looking for a simple chip to 4 x multiply the Amiga 14Mhz clock with .... and found this...

Although this card is only 24 bit address bus ... remember buffee will be able to do 32 bit address space internally and *MUCH* faster. Its not like the upper 8 bits on the A1200 are connected to anything anyways.

Renesas had some fun with that, or they were so serious that they didn't even notice that they started with .... in the datasheet.
Nice find, the only problem is they only have 36 of them in stock and Renesas just had a fire on March 19 in one of their facilities:

Count me in for the test, I'll have a recapped A1200 on standby :D
