I beg to differ. Both were based on the 6502 microprocessor. The POKEY sound chip in the 8bit ataris was superior to the C64. It was 4 channel versus the C64s 3 channel.
Futhermore, the 800XL, the 1200XL, the XE series all had a parallel bus port (though never used by Atari), 2 third party manufactuers took advantage of this. IT was able to handle hard drives, parallel printers, and high speed modems. I had a 19.2K modem attached to the PBP, a 10MB hard drive, a printer, and an 80 column video card.
The C64 did not have as many alternate operating systems as the 8bit atari. I ran on Spartados X, which was like an advanced MSDOS for the 8bit atari. The Atari also had third party BASIC carts.
There was tremendous "vaporware" made for the 8bit Atari, some of it was introduced to the market in experimental form, others never made it. Atari even made an advanced version of the XL series called the 1450XLD - only a few made it to the market (they're collector's items.)
After market companies also made DD/DD 5 1/4 high speed floppy drives. And one manufactuer even was able to use 3 1/2 drives. I KNOW - I had one!
The 8bit Atari was so WAY ahead of its time. It lasted far longer in terms of experimental use on the market than the C64 ever did. Now I know at lot of C64 enthusients will point out that the C64 tended to have a more stable operating system and slightly better base graphics. This is true when you take into account the base system (atari DOS vs. C64), but when you factor all the expansion exploits, the Atari won hands down. :angel:
