you need a modulator or a modification to go to a normal TV. Otherwise its black and white. They make a nice svideo board to do regular TVs. and the flickerfixer!
Anyway what you want for the ultimate Amiga experience is either:
A1200 w/ a hard drive + proper ram expansions + accelerator (maybe) + WHDLoad plus a full install of OS possibly w/ kickstart rom upgrades (to install a newer OS)
A4000 w/ the same. The 4000 is easier to modify since rather than being a wedgeboard, its a desktop. You can get nice accelerators and shit. Even a network card and surf the net all gimped 1995 style.
So one of the above w/ hard drive and ram expansions, and os3.1 or better is good..... you can get away with an older OS but its kinda lame. Then, you can download games for whdload and play them. You generally dont need an accelerator unless you are going to play 3d games. The reason for WHDLoad is for compatibility with the different processors, etc. (And for free games!)
That being said, and with all due respect to Amigans, f*ck the Amiga. What a waste of time and money. If you didn't experience them when they were current, getting one now is just a bad idea. The arcade conversions are gimped compared to other systems of the same era. Getting a working model up to speed in order to easily play games is a pretty hefty investment....and even then you get the whole thing setup, and it takes a big deal of space....for a less than <3 experience.
a solid A4000 will run you 500+$ on a good day, and a solid A1200 maybe about 350....... and youll still need to get a composite or svideo solution after that.
Definitely not worth it because you're in it for the games, and not the Amiga computer experience , I think.
If you want to diddle around with Workbench, and actually try using the thing seriously, then by all means go for it. Hell, PM me even, I know people who can hook you up with nice Amiga systems.
and in the end you could emulate it and be fine. The "real hardware" experience is not that great, and I speak from experience. I've had an A500, 1200, 2000, 2500, 3000 and 4000
I still have a 1200. I think. They really arent worth the time unless you just have to play the exclusives or if you are programming / using workbench.
I think youd be better off spending the $$ on a nice imported Japanese computer, like an MSX. Definitely cooler IMO.
