R38@PSUVM.BITNET (aka Marc Rifkin) (03/26/88)
At a recent MACshowoff, I found that the MAC II has 16 million colors,
and a resolution of 640x480. BUT an unexpanded M2 can only display
16 colors at a time. You have to buy a VIDEO CARD to give you 8 bit
planes for 256 at one time.
I feel that 320x400 with 4096 colors at one time looks at better.
And now the PVA graphics card for the A2000 gives 24 bitplanes (at, I
assume 640x400 or higher in overscan), so then the Amiga can display
ALL YES ALL 16 million colors at once.|_
What's the point? With cards, the MAC II costs 2 times the Amiga.

Ok, as far as rumors wash on my shore, PVA looks like this:
2 boards, one in video slot, one in an expansion slot
Developed by NYIT
Contains: FRAME GRABBER, GENLOCK, FRAME BUFFER (24 bitplanes (16mil colors))
Price about $800|
Looks to me to be in same order as Video toaster by NewTek

The Video-Toaster version that I've seen demo'd (I don't think NewTek has decided just what all will end up in the marketed product), had considerable on board *processing* capabilities, for doing various video effects (wipes, fades, pixelizations, surface mapping, replication, montage like effects, etc). They also said they'd be offering some additional add-ons, including one with the TI graphics processor chip (TMS?????), that would be programmable by the applications s/w. The PVA sounds very good, and I'd like some more info. Who can I contact? Also, can it be put into a "FlickerFixer" mode (i.e., can it be used as a deinterlacer/scan-doubler)? See! I *knew* there weren't enough slots in the 2000!

Such a beast is in the works "reported a >highly placed Amigazoid source" at a BAADGE meeting from a few months ago. >I can't name the source, but he answers to "duck". I have talked to Dale about the graphics libraries, and his ideas for hooks to make them more extensible. I am under the impression that current work loads have moved this work into the not yet scheduled future. Additionally, we need access at a higher level then the previously discussed bliter hooks (i.e. to take advantage of hardware ellipse capabilities). Finally, since we will have hardware RSN I need another solution. We will probably implement a low-level driver for the board and an X-V11 driver. This can tie into Dales X implementation and provide quickly demonstratable applications. Comments? Having a compatible graphics.library for our card is still the long term goal. This would, however, require an aggressive top-down attack. -- Rich miner@dino.ulowell.edu 617/452-5000x2693 UL-CPE Imaging Research Lab
