[comp.sys.amiga] Amiga 520 video adapter

billh@tekig4.TEK.COM (William Hansen) (08/24/87)

My dealer has these new flyers with new amiga products it shows a
little gizmo called the 520 video adapter. It has what looks like a RGB port
on one side and a pair of RCA jacks (why two?) on the other. It is displayed
in a manner to look like a 500 accessory, but I thought the 500 already had
composite output, so what exactly does this do?

a) Composite *color* output (A500 output is nice clean gray-scale monochrome)

b) RF modulator (see pretty colored blobs on TV - actually it's pertty nice...)

If I were to make a guess (and I am :-)) I would bet that the little gizmo
is a composite color + composite audio output. You need something like that
to talk to a VCR directly. Add video/audio in and a selector switch and
you've got all the inputs of a GenLock. (Note that the A500's built in 
composite video is a monochrome (greyscale) output for better clarity on 
mono monitors)

These opinions are my own and no one elses, but you knew that didn't you.

You read the sales flyer and your *still* don't know what it is??  What does
this say about the quality of the sales flyer?!

If I'd believed Commodore sales flyers I'd know that the Amiga can control
"up to 50 overlapping windows"
       ^^
Who needs Jack Trameil (sp?) to spread mis-information when you can just
use Commodore advertising? :-) :-)
In case you don't get it... the Amiga can control as many windows as you
have ram for.  There was a sample program a while back that opened 150
windows at the same time.  One of the principal features of the Amiga is
it's "no limits" design philosphy.
(Sources-> Spring 1987 Commodore-Amiga Buyer's Guide, page 2  and a
 Single sheet A1000 description from an Amiga dealer, about January 1987)


If that A520 costs more than $179, consider the Mimetics ImaGen.  I've seen
the output... it is quite good.  ImaGen gives a RGB pass thru, color
composite video out and _genlock_ input for syncing the Amiga to an external
video source.  It fits all Amigas (A500,A1000,A2000).  ImaGen is missing
audio in jacks... a feature that the Commodore 1300 Genlock does have.

The A520 should go for quite a bit less than $179, though I'm not sure what the
final list price is supposed to be.  From what I've heard, the ImaGen should
be a pretty nice device, however I haven't seen a working unit.

The A520 connects to the RGB port of the A500 and provides several features.
First, it provides composite color to monitors that cannot handle RGI.  Second,
it provides RF out to connect to a TV.  You connect the left and right audio
outputs of the A500 to the A520 via a Y-adaptor.

The A500 has composite monochrome built-in, but not composite color.

There's an Amiga retailer in Los Angeles, name of "S.O.S. Computers" who
frequently runs an ad in the L.A. Times Saturday Sports Section (chock
full-o-computer-ads) which says something to the effect of "[The Amiga]
can run up to FOUR programs at the same time."

Although this text is accompanied by clip art supplied by CBM, I'm
fairly sure the text came out of S.O.S. themselves. I haven't talked
to S.O.S. and have no idea how they came up with the number "FOUR" 
as Amiga's multitasking limit but I wish they'd cut it the hell out.
It's stuff like this that can be imbedded in the brain of a potential
new Amiga owner, and foister the creation of yet another 'urban myth.'

I was in Germany this past week, and in one store I saw this thing hooked up 
to the A500 --- It looked like the C64 modem, and it said "Amiga Video 
Adapter." The Amiga was hooked up to both a monitor and a giant color TV.
So I imagine this "thing" was the (European version of) Amiga 520. The price?
59 DM --- About $35. 

I visited 3 large department stores (Horten, Kaufhof, Karstadt), and all
had Amiga 500s. (Price 1200 DM --- About $660 (And no tax, of course))
Unfortunately, none had A501 expansions, and only two had the Amiga 1081
monitor (800 DM, $440). I brought saveral demos with me (to show my
dad), and while I was showing it to him on the A500 in the store a crowd
gathered around. Even the dealer was impressed (he had never seen the
Juggler!) and asked if he could copy the disks. I gave him all the PD demos
I had with me, and he was real happy... And when I ran good old Boing!,
someone exclaimed "I saw that on the ST!". So I had to show them how
the Amiga differred --- By bringing WB over and running Oing! at the same
time.

Anyway, it seems like PD stuff has a hard time getting over there, so,
when you visit Europe make sure you bring some near PD demos over and
give a few copies to your local dealers and friends. 

But, overall, compared to the last time I was there, I saw a lot more Amiga
stuff (programs, books, mags, etc...). And I think I might've even convinced
my dad to get an Amiga system. 8-)
