Well these are the new custom chips I would like to see ...
  Mary - Mary is a serial interface chip optimized for MIDI applications.
	She has two 31.25K baud serial ports and a 16 bit timer that
	provides .1 millisecond resolution. She has a 32 bit bus and
	when you read a word you get the two MIDI data bytes and a 
	16 timestamp. She will optionally generate 'double zero' bytes
	when the timer rolls over. (About every 6.5 seconds)

  Paula - She has had here counters reworked so that she can generate
	16 bit samples (8 channels) at 48 Khz. Additionally, the divisor
	channels are replaced with additive synthesis dividers which give
	linear control over the frequency. 

  Agnus - Of course agnus addresses the full 2Meg of CHIP ram.

  Victoria - Victoria is a new chip with 20 floating point registers 
	organized as a 4 X 4 array. Built in trancendental support 
	allows here to do a vector transformation in 21 cycles. Victoria
	has two DMA channels, a source and destination. When started
	she will burst fetch "n" elements (1 - 4) from the source
	DMA pointer, apply the transformation and store "m" elements
	(1 - 4) in the destination DMA address. Further there is a 
	number of "points" register that limits the total number of	
	vectors fetched.

  Denise - Well Denise is of course expanded to 8 bits/pixel and 16M colors.
	Display modes are bumped up to 800 X 600 in color, 1600 X 1200 in
	monochrome. The C1180 is Commodores 19" color RGB multisync monitor.

Fooey, if I wanted a stupid Mac I would have bought one. The only reason I
can see you wanting this is to let you run software that the Mac currently
runs. I envision that the Mac and PC people will port their stuff to the
Amiga because it offers the most bang for the buck and the nicest environment.
That and the 10,000,000 Amigas in the world that C/A will have sold.
