Difference between Amiga and Atari 520?

[stopthegop]

it didnt have much expansion though. that was really the problem with most st series computers. you could add tons of stuff to almost any amiga but the st's were all kludges.

That was somewhat true with the low end STs, but not so with its cousin, the TT030.  The concept there was a computer so loaded with hardware features already built-in that you wouldn't need to expand it.  Vintage late 1988, Mine has:

68030/MMU @ 32Mhz
6882 FPU @ 32Mhz
64bit memory (32 address,32 data) -- 28MB!
Aftermarket memory expansion possible to 152MB!  In 1988!
External ROM port
Internal 512K ROM OS.  You can ALWAYS boot to a gui
Independent keyboard processor
3x asynchronous RS232 serial ports
1 DMA rs422 port
VGA Graphics built in
VME slot for expansion
external DMA "ASCSI" port
external floppy port
external standard printer port
Game cartridge port
2 mouse/joystick ports
rj11 keyboard port

Granted, the TT was expensive.  But you can't tell me that it wasn't state-of-the-art for its time and, imho, for many, many years after.

I forgot..

DSP processor
MIDI in and Out
16 bit Stereo w/ high quality RCA jacks

You're right, 1988 was a mistake, I meant 1989.  But we're both off by a year because it was in fact released in 1989. This I know for a fact because 1989 was the year I graduated High School and I used my Dad's new TT030 for both semesters of my first year of college, starting around Aug, 1989.   The memory expansion I mentioned was available around that time as well, no more than a year after the TT was released.  It was a 128M expansion and I remember it being hugely expensive.  Believe it or not, there was actually one on ebay just a few weeks ago..  I mean the 128M RAM cage.  Sold for around $200.  As for the ROM port, that was a mistake on my part mentioning the same thing twice.  For sure though, the TT030 was released in the 1980s, and it was most definately a better machine than any crapintosh of the day (sorry, I'm just really allergic to mac/os in general -- the software, that is), light years ahead of anything from microsoft, and in my estimation, about equal with Amiga at that moment in time.  But again, the TT cost around 3 grand when it came out, 4 grand if you wanted memory.  So I guess it all came down to price?  I suppose thats why the PC "won": price.  God knows it wasn't the product.

Windows users think that just having two programs loaded in memory constitutes multitasking.  I've always said that unless you've used an Amiga, you've probably never seen, much less experienced, true pre-emtive multitasking.  That still holds true today.  Just recently I formatted 10 SFS disk partitions on three separate scsi drives on my A4000...at the same time.  Try that on a PC!
