#Amiga 2500

Jim,
No, the cards can't go into an A500, it requires the co-processor
slot…which the A500 doesn't have. Now, that doesn't mean that someone
couldn't come out with some form of expansion device that would add a
co-processor slot to the A500….but I suspect it would not be a reasonable
alternative.
For all intent and purposes, the A500 is very limited as to it's
expansion capabilities. It was designed as the 'low end' of the Amiga line,
and as such, isn't a versitile as the A2000 as far as expansion, power
supply, video capabilities and a few other things.

Are they going to "fix" Hi-res mode on A2500? ( Will they get rid of
Flickers?)
Junichi!
Junichi,
There is nothing wrong with hi-res mode…what's wrong is that the
monitor has a phosphor that is too fast for interlaced video. A monitor
change (which is reported to be comming) takes care of that very nicely.
To match NTSC standards (TV video standards), you need interlaced
video. It's the interlace (writing every other line every 60th of a second)
that causes the apparent flicker. Each line is written only once every 30th
of a second…and between writes, it fades. That leaves you with a bright
line above and below a darker line (the line above and below being just
written lines…the darker line having had a chance to start to fade).
When that occurs on a horizontal line between high contrast colors,
you get the perception of flicker. Note that it doesn't occur in solid color
blocks, nor does it occur on the vertical edges…only on horizontal edges.
You can buy long (or medium) persistence monitors right now, but they
are a bit expensive (+$1000 for the most part).
Don
Oh, I see…So, you mean, There is a flicker just because Commodore2002 or
Amiga monitor is cheap. I see. So if I use "real" monitor, I don't have to
warry, is that what you meant? I see… What video monitor do you recomend?
ummmm…I have a NEC analog monitor for my NEC PC9801VX…
I wonder I can hoock it up to AMIGA some how….
-Junichi!
Junichi,
NO, it's not because it's a cheap monitor…it's because it's designed
for fast graphics and thus needs the short persistance phosphor. The flip
side of a long persistence monitor is tha fast moving objects, such as the
mouse…will 'smear' or leave a trail across the screen.
Read the file MONTOR.TXT in DL 11 for more information.
Yes, you should be able to use your NEC monitor with the Amiga.
Don
Don,
I assume by your response that the boardwill fit in a 2000? I have a 2000,
not 500, must have typed the wrong number.
Jim Vogel
Jim,
Yes, the boards designed for the A2500 series will fit into an A2000
since the A2500 series is nothing more than an A2000 with the boards in it.
The 'base' computer is not different than that you have now.
Don
Don, you mean that people that have the A2000 can makeit a A2500 by adding
the board(s), and if course will be more expensive ? or by buying
an A2500 you will save some $$$. Why CBM did not put the '020 stuff
on the motherboard with some hardware that will detect specific
'000 code and put a filter for those deadly instructions…anyway…
from my seat I see that having a A25000 with the '020 boards is
giving you a new big powerful door but you are taking a slot
a precious slot…how the memory chips of the A2500 are they
relly 32 bit mem chip or just some kind of fix from the A2000…
maybe I am talking too much but damn '000 tech is out in order
to compete in a clear meaningful manner…RISC chips are spurring
everywhere…including in the motorola line ( 88000 ) not many
workstation makers will support the '030 except HP to a extend
SUN, APOLLO, Silicon Graphics , Prime they are going for the RISC ( risk
in a sense ) even IBM !
Bottom line…CBM don't lose your chance to knock a lot of people
ou or better to garb a juicer market like the c-64 did…we are
waiting and waiting…but not forever…where is that truly based
'020 Amiga ?!?!?!? needless to say work on a parallel processed Blitter
Amiga based on multiple CPU and ypu will send
a lot of companies to their Doctor ( or broke… ) . Well I think that I
let ALL of my
stress out…after our SUN corrupted a master HD…!!!
Ed,
I can't think of a better use for a slot than to add 2 Meg (or 4 Meg) of
real 32 bit RAM AND a 68020 AND a 68881 AND a 68551 all at once.
If CBM wanted to put the '020 on the motherboard…they would have had
to design a new computer and that would have put the A2000 into a bad
position for future sales. By making their entry into the '020 business
simply a board for the A2000…they have insured the success of both the
board and the A2000.
The '030 machine is a different story…that will be a whole new machine
and rightly so.
Don
I hope that they allow for the expansion (Hardware + Software) of the
32 bit address range. 8 megs is great but all to soon its going to feel like
a 4K trs-80 did in 1977. There are WONDERFULL things happening in the world
of computers! And making everything expandable just makes it happen faster!
I am very glad that AMIGA started off so much further ahead than the
other machines! Sayiing that the MAC II is (or model 80) ahead is
a misteke. The OS for amiga is the begining of a whole new world
for computer fans. Its not tied to big bucks or the old old old world
of 8008 8080 etc. Gosh I sound like a computer nut!
Thanks for letting me sound off.
