If you're thinking of dithering it just to print it out, the printer drivers
for 1.3 have an option to do Floyd Steingberg dithering.

I forget what restrictions/limitations it has on it, though.  That information
is given in the manual for the "Amiga Enhancer" upgrade to 1.3.

Ok.  HEY COMMODORE!!!  HOW ABOUT A "A2640", 50MHz, 68040 board, that can hold
up to 8Mb of RAM, (that you can get with 0K installed), and with a
daughterboard expansion bus, that you can put, say, 3 boards on, for up to
256Mb of RAM!!!

What are you staring at me like that for, Dave???  I don't expect it TOMORROW!!!

Next week would be nice, though!  :-):-):-):-):-):-):-)

Seriously, I hope that Commodore is at least looking into making a 68040 board,
and down the line, a 68040 system (with 32-bit graphics/sound chips, etc.)


Also, here's an idea for some hardware company.  How about a DMA Hard Disk
controller/Memory expansion card that connects to the A2630's daughtercard
connection?  Make it so that it can do either 16-bit or 32-bit DMA, depending
on whether it's talking to the Zorro II bus or the A2630 daughterboard.

Not being a hardware expert, I have no idea how difficult this would be, so
don't flame me, but I was wondering, would it be worth it?


OH!!!! You meant suggestions about using Floyd Steinberg dithering!!! OOPS!!!
