AmigaWorld re V Toaster
4 messages in this thread
In a quick scan of the February 89 preview of the Toaster, unless I understand
correctly they've made a decision or two that personally I disagree with,
unless of course I misunderstood what was said or the finished product is
different from what is described.
The article describes a single board in the 2000's video slot that includes a
broadcast quality RS-170A output that can be used with the built in genlock,
the ability to take an incoming NTSC video (composite video?) signal, allow its
manipulation in a number of different ways, but will not, I repeat not, allow
the use of a VCR as the input unless one uses a Time Base Corrector they may
choose someday to sell at an unspecified date or price. This is what I
consider the main problem. I wish to use a vcr, probably S-VHS thru either YC
or composite video outputs as the input to such a board for some work. Sure,
some work will be done using the board simply as a digitizer, with a 450
horizontal resolution line color camera as the input, which I would hope would
provice good results with minimum hassle, but other work would have been tape
based for input. There is also an issue with the way you display graphics
while working on them – Toaster and Amiga graphics cannot be on the same piece
of screen at the same time. I don't know how much of a problem this will create
– after all, you can now do things that currently weren't doable at all on the
Amiga, and this limitation may not be considered a problem.
To sum up what I read and what I think about it, if it comes out as scheduled
for a decent price, if the TBC comes out very quickly and very cheaply allowing
VCR input, and if the software provided plus extra software to do more is as
good as it sounds in the article, this should be a very good product. Note
that according to the article CBM had not yet made any definitive announcement
re the PVA, so that for someone doing semipro work using the Amiga this may
well be the best choice.

Ron, I don't know what AW's deadlines are like and I don't know what you
consider a "definitive announcement" but I received a "Technology Preview"
("Premilinary – Subject to change without notice") in mid-December. It
describes the A2350 PVA in substantial detail.
The PVA sounds at least as real as the Toaster (which is not at all). If this
is news to you I'll be happy to share the details of the spec. sheet. — Art
I assume that like any other mag AW has to finalize a long time ahead of print
date. CBM has 'previewed' the PVA, but it is not an announced product as far
as I know. Yes, I would like to hear details of the preview, but no one knows
that CBM will ever make it an official product. I certainly hope that they do.
Just for the record, Max Toy has stated publically that a preview is just a way
to show off something that they are working on, but may or may not ever be
released.

It may never see the light of day but here is the 2350 PVA spec sheet with some
obvious stuff removed for brevity:
FUNCTION: Genlock. Real time freeze frame. Digitizing of images into Amiga
pictures. Frame buffer.
INPUTS: Two composite video RS-170A via phono jack.
OUTPUTS: Composite video via phone jack. RGB via 23 pin D connector
CARD TYPES: Frame Store Board in 100 pin slot and Video Interface Board in
video slot
GENLOCK: Syncs to exteral source. Overlays Amiga graphics on external video
and displays both on Amiga display or outputs combined video signal as
composite and RGB. <doesn't tell you much, eh? — Art>
FREEZE FRAME: Freezes a single video field in real time. Will store odd, even,
or both fields in full color. The freeze frame memory is accessible by the
Amiga for loading, saving, or modifying the frozen image. This digitized image
can then be transferred to the Amiga's video memory (resolution: 740×485).
DIGITIZER: Works in all Amiga resolutions including HAM. Uses user selected
or computer optimized palette. Software includes dithering algorithm.
— end spec sheet
Notes: This is a micro version of something called the AGILE-2000 developed by
the NY Inst. of Tech. (never marketed). Frame grabber resolution is 740×485.
The hardware is bundled with PVA PAINT to manipulate the images.
