The new A1200s come with original factory manuals, cords, mouse as they were packed in the Selectron factory.  The A1200 is packed in original pink plastic.

Actullay what I was looking for was hard drive and memory specs more specifically...

Oh, Selectron France or Asia ?
But why don't you buy a second hand european TV with the A1200 or a Sony Broadcast monitor ? and why do you want to loose all the video quality with an RF or Composite connection ?

You add a hard drive and memory as extra's during the ordering phase through Amigakit.com from what I can see on the webpage.

Basic A1200 came with just 2mb Chip RAM and no hard drive from what I can remember ... might be wrong but it's my age you know lol

So what I am hearing is that aside from changing the power supply and booting to NTSC the A1200 PAL and the A1200 NTSC are functionally the same.


I thought this for a long time, but NO, they are not.

Amigakit is correct about the differences between a PAL A1200 and an NTSC one.  

As I understand it now.... While you can switch to NTSC or PAL in the boot menu, it doesn't change the color encoding, only the display timings.  So when you put your native NTSC Amiga into PAL, you don't get true PAL.  You get PAL-N (PAL resolutions and timings with NTSC color).  And the inverse is also true.  When you soft-switch your native PAL Amiga to NTSC, you get PAL-M (NTSC resolution and timings with PAL color).  

The support of any PAL modes may be considered spotty at best on US TVs -- and which ones of these modes will work on your TV is anyone's guess.  :-(  If you're shopping for a new TV, it's probably best to simply try it and see, as the documentation won't say, and any salespeople you corner will most likely treat you as if you suddenly grew an additional head as you try to explain the question.

Please explain why my 21" Sony Trinitron video monitor (no UHF decoder) displayed Never Twice the Same Colour hue changes when using NTSC screenmodes, and correct PAL colour when using PAL screenmodes, from the composite output of my A1200.

Well, that is a very good question.  Without knowing for sure the details of what signal is being outputted and what the monitor is doing with it, I couldn't really tell you.  Heck, maybe even something in one of the motherboard revs or RF/Composite boxes is different between various A1200s.

This is a topic that confuses me, and honestly, I don't know the answers.  My empirical data consists of one TV that can supposedly accept PAL or NTSC by changing a couple settings in a hidden unlock menu.  When set to PAL, I get erratic lose color losses out of my NTSC A1200's PAL mode.  It worked fine with my friend's native PAL CD32, though.

Take THAT ball of confusion for what it's worth.  The PAL-N/PAL-M explanation was the only thing I've heard that made sense, but it may well be in error.  I don't have the equipment or experience to really say for sure.

ETA: Actually, a lot of the color encoding hassles may be limited to the A1200 RF port only, but I'm not sure.

Colour encoding problems are inherent in the original NTSC standard. The whole point of PAL is that it eliminates those swings of colour (so no hue control but a saturation control instead) but it does require more complex and so more expensive circuitry. The US did not choose NTSC for quality, but for cheapness. Any colour is better than monochrome, yes?

Edit: anyway, back to the OP once again, if you use an RGB monitor (or use RGB input into a suitable TV) then you should not experience any such problems.

It would be nice if Amigakit would actually answer this question since they are on this forum from what I have seen and they actually sell the computer on their site....

Amigakit???

after wwII the us developed a tv system based on b/w signals and had several million tvs in use when color came along. rather than obsolete all those tvs they piggybacked the chroma signal ontop the luma so that both color and b/w tvs could receive the same signals and produce the same (colorless obviously for b/w) programming. sloppy but effective and commercially viable.
from what i understand european countries developed their tv systems later so could choose the somewhat better system (better color and resolution lower screen refresh speed)
sorry i love old tech stuff - tubes and stuff i still have an old tube b/w tv, and no i t ddoesnt work with a pal 1200
Oh yeah?!?
Well your stupid bit is set,
and its read only!
