if it will be possible to add a math coprocessor to those Amiga 1200 which

I'd appreciate very much any info on this subject, because I intend to

For the average user no, however there should be expansion products
which provide for an 881/882 and/or memory expansion pretty soon.
I believe at least one well-known 3-rd party vendor has already
announced such a product.

It's possible, but it's tough. So it can't get recommended for anyone who
is not *really* *very* experienced with SMD chips. The solder pads for
the SMD version of the FPU are there. If you are one of those few SMD
experts and have the right equipment, then you can add the FPU. For non
experts this is one very sure way to destroy your A1200. Keep off if you
are not educated and equipped!

I saw an AmigaWhirled today where they (albeit hurredly) reviewed the 1200.
They said the math coprocessor was "optional". Some option, eh?
Also, I can't tell from the pictures what the ports are? My main question
is how many video outs there will be? I.e. can I hook up my old 1080 and a
cheap SVGA monitor at the same time (if the 1200's composite output is
color, this would be ideal) so's I can use all the video modes w/o having a
multisync? (I can't afford one!). What's that "port" between the power cable
and the RGB? Is this the rumored built-in RF modulator? If it's completely
separate from the composite that would also be nice. :)
Thanks ...

There are 3 video outs: RGB, Color composite, and RF Modulated.

Physically there are 3 outputs: RGB (23-pin), Color Composite (RCA) and an
RF output (RCA plug). But there is only one source (as in all Amigas).
Which basically means they will all show the same picture. But composite
video and RF output is restricted to the 15kHz modes. Not because of the
Amiga, but because composite video and RF (TV-sets) are 15khz ONLY.

Depends. If your cheap SVGA monitor will sync to 15kHz you can.
But it probably will not. If with 'all video modes' you mean the full
frequency range (15kHz to 31.5kHz), you _WILL_ need a multisync monitor.
(That's what multiscan/multisync's are for, affordable or not ;-)

It IS the RF modulator. Why would you want it separate from the composite
video ? It will need composite video as input to work anyway. An RF modulator
produces input to a TV-set, and thus MUST be 15kHz.
The A1200 has a lot of different resolutions and screen modes. Some are
intended for video use (as in VCR's, cameras, etc.) Those modes run at
appr. 15 kHz (PAL and NTSC) and are available at all 3 outputs. Those
modes require monitors/VCRs/etc. that will sync to 15kHz.
Other modes gives you horisontal syncs between 29kHz and 31,5kHz, and is
only usefull via the RGB port. To be able to use all of them you'd need
a multisync monitor. VGA monitors normally only syncs to one frequency
(or a narrow frequency range), which restricts those monitors to a limited
number of screen modes.
To conclude: Not all modes are usefull to all monitors, but all monitors
are useable at one or more modes.

You have the 23-pin RGB like on any Amiga, an RCA jack for color composite
and an RCA jack for RF out.

Yes, possible. But when you use one of the non-15-kHz modes, it would be
better to switch off the 1080 to not confuse it. (You know, that blue
smoke type of confusion...)
>What's that "port" between the power cable

Without looking, I guess: yes.

Yes, it's separate, nice eh?

Yep. I was one of the people who said that it is possible to
add an FPU to an A1200 motherboard, but it's not a job you can do at
home. If you try this with an ordinary soldering iron, even with a very
fine tip, all you can expect to achieve is to kill your A1200. Soldering
an FPU to the motherboard requires specialised equipment and the training
to know how to use that equipment properly.
Actually, I've been wondering if repair centres will advertise
that they will do this for customers. The ones authorised to do
warrantee repairs for C= might not, but some of the independent ones
might.

as I'd like to buy one and I'd prefer to get one with the co-pro.
Also what are the specs for the 1800 ?? I haven't heard anything
about it yet.
Thanks,

The 1200 does NOT have a math Co-Processor!!!!!!!!!
It has room for it but no math co-processor. To install one, you need
special equipment and special training use that equipment.
What's an 1800? Maybe the reason you haven't heard anything about it is
because there is no such a thing as an 1800.

The 1200 doesn't come with a math co-pro , it does have surface mount pads
on the board where one could be mounted but neither Commodore nor any third
party vendors have said they will updgrade the 1200.
I have the tools and experience to add a 68882 to my 1200 but I'm not
going to .I preffer to wait for some of the third party add ons to appear.
One thing to keep in mind is that If a 68881 or 68882 is added to a 1200 it
will be running of 14.XX MHZ and you would most likely have to provide an
alternate clock source as most people would want a highr speed co-pro.

1) no current configuration includes a math co-processor. One can
be added on a processor slot epansion board, soon to be available
from 3-rd parties.
2) There is no such thing as an A1800 - it's a paper tiger generated
on the net...

There had been a car called 1800 manufactured by BMW 25 years ago. Maybe he's talking about
that? =8-)

Wait for the MicroBotics fast-ram/copro expansion card.. It should be available
next week or so..

and it only costs $149 retail. Why are people in such an
uproar when the 1st peripheral available already has a math chip
on it???? You NEED Fast RAM anyway, for decent performance,

The Microbotics board is called the MBX1200 , it can take up to 8meg
ram in just "1" SIMM socket , I don't know how much it comes with .
I suspect 0k .It doesn't include a clock which I found very surprising ..

Is the RAM 16 bit or 32 bit. It really should be 32 bit for it to be useful.

It isn't marked on the box because C= doesn't supply a math
co-processor for the A1200. While there is a position on the motherboard
for a math co-processor, C= decided not to put it on to save costs. The
most likely way to add a math co-processor will be to buy an expansion
board which has one fitted to it. Adding a math co-processor to the
motherboard isn't going to be easy (there's no socket for it), and
will require specialist equipment and skills.

C= hasn't mentioned an A1800. This machine was speculation
by a journalist working for a British magazine. So far none of the
other magazines seem to know about it, so it's a fair bet the A1800
is just wishful thinking.

Well, George Robbins very recently said there is no such thing as an
1800, that it is "only a paper tiger invented by people on the net".
