Video & Amiga
Just my two cents worth (and with inflation, you know what that's worth)…
The A3000 would probably be the platform to go with a year from now. At
this time, however, much of what you will be wanting in the hardware line
simply won't physically fit in a 3000. Depending on the date the grant is
to be awarded, you should keep this in mind.
At this time, I would opt for a 2000HD with a GVP accelerator (40 or 50 Mhz
style.) A daughterboard for the GVP accessory is currently available,
while there is none that I know of for the 2500. Your intended uses are
all memory intensive, so the added 32 bit memory will be a big plus in
going this route. Additionally, a removable media device, such as the
Sysquest, will be invaluable to you.
While you do not presently plan on preparing broadcast or instructional
material in house at the present time, planning on the capability of doing
so would be quite a benefit to you. Your students will very likely
surprise you with the quality and creativity of their work, and being able
to produce this work in a quasi-professional manner could be quite a bonus
for them – not to mention the impact it could have with sponsors in the
continuance of your grant or obtaining supplemental grants. Your equipment
list looks like you are almost there in this matter, so consideration
should be given to this matter.
Video toaster is cute, and it does nice effects. However, it would almost
certainly require a genlock (in any case) and a time base corrector to
substitute for the frame-grabber/genlock combination. You might be better
off considering the frame-grabber and genlock as a base line, and add the
Toaster if the grant allocation allows for the added expense. I will leave
it with others to suggest specific devices. (I would think the Impulse
VD-1 frame grabber and the Supergen 2000s would probably suffice for your
needs.)
