kulaspg #1 Posted November 9, 2003 I have an Atari 800 and 800XL for sale on ebay. Auction number 3057970880 and was wondering what is the difference between the 2 units. Quote Share this post Link to post Share on other sites
Bryan #2 Posted November 9, 2003 800 - Came with 8K-48K (expandable) 800XL - Came with 64K 800 - BASIC on Cartridge 800XL - BASIC is built-in 800 - Two cartridge slots 800XL - Second cartridge slot was dropped, and the Parallel Bus was added 800 - 4 Joystick ports 800XL - 2 Joystick ports There are a few other differences. The XL has a newer OS with a built-in Self-Test mode and a HELP key was added to the keyboard. They are both compatible with the same software (with a few exceptions). -Bry 1 Quote Share this post Link to post Share on other sites
Mindfield #3 Posted November 9, 2003 A few other important or esoteric differences. 800: CTIA ANTIC chip (graphic modes 0 through 11, 128 colour pallette) 800XL: GTIA ANTIC chip (addition of graphic modes 12 through 15 ("GTIA modes"), 256 colour pallette) 800: "Memo Pad" comes up when booted without BASIC cartridge. 800XL: BASIC is built in, thus no memo pad. 800: Early models had a removable top cover to reveal 4 expansion slots (slot 1 reserved for OS, 2-4 were designed for other expansion, such as RAM/RAMdisks, modems and 80 column cards) Later models had no expansion. 800XL: The only expansion was through the rear PBI (Paralell Bus Interface) Quote Share this post Link to post Share on other sites
Nukey Shay #4 Posted November 9, 2003 Only early models of the 800 used CTIA...this was later changed (and existing 800 owners could have their computer modded). Quote Share this post Link to post Share on other sites

Bryan #6 Posted November 9, 2003 Nukey and Joe are right. 800: CTIA ANTIC chip (graphic modes 0 through 11, 128 colour pallette) 800XL: GTIA ANTIC chip (addition of graphic modes 12 through 15 ("GTIA modes"), 256 colour pallette) Most 800's shipped with GTIA too. There were not a lot of CTIA machines made. Apparently the story is that CTIA's are actually GTIA's with the extra modes disabled because they were having problems and needed to ship the first run of machines. Later, the problem was fixed and true GTIA's went into production. 800: Early models had a removable top cover to reveal 4 expansion slots (slot 1 reserved for OS, 2-4 were designed for other expansion, such as RAM/RAMdisks, modems and 80 column cards) Later models had no expansion. They all had the expansion slots. Atari just screwed the top closed (no flip tabs) after they had been shipping only 48K units for a while (they also stopped putting the RAM cartridges in cases and put just the PCB's in the slots). -Bry Quote Share this post Link to post Share on other sites
+boxpressed #7 Posted July 21, 2011 Thought I'd resurrect an old thread. I want to get an 8-bit and have narrowed down the choices to the original 800, 800XL, and 130XE. I'll use the computer to play games almost exclusively (no programming), and right now I'm expecting to play cartridge games. I'll probably want a multicart at some point. I like the original 800 for the retro look, but will I be able to play any cartridge game on the original 800? And do games look better on the 800XL because of the GTIA chip? Thanks in advance!

Some early games do not work on the xl or xe. And many later games won't work unless you have 64k or more ram, which means you need an xl or xe. It depends on which games you want more.

It depends on which games you want more. If I am not wrong, earlier 800 games have been patched to run on XL and XE (but you cannot play 4 player games), but many newer games don't work on 800.

Bryan #10 Posted July 21, 2011 Yeah, the XL/XE is the way to go. All the stuff (of value) that had problems on the XL has been patched. The 800 can't run anything that requires 64K. Quote Share this post Link to post Share on other sites
