Let me bring up an old topic : doesn’t antic have to match the dram type?

Are these binary files intact and not missing line feed characters?

It could be. There was a special cable that you used to connect a serial terminal to the sio port on the ATR. No Atari needed to run CPM.

Yeah cleaning up these files is ugly! CRs were completely nuked. You can kind of make things out by replace \t\t with \r\t\t but that makes messes of tables. I have no idea if this table I tried to restore is correct.

I didn't realize they were that unclean. I see the page header command in there but it looks like all the returns and line feeds have been removed. I few quick Unix scripts could clean them up. Is there something you want me to look at first?

Would this have worked if you used a real BASIC cart in the Left slot?

So I noticed this today, perhaps its been talked about: https://atari.com/products/cx78-gamepad I always wanted a pair of the original 78 gamepads but they are expensive and hard to get in the US.

This pic is so sexy I want to get out an 800 from storage and use it as a daily driver. My 1200XL will be sad.

PC version manual is here, I'm not sure if the dip switches would be any different for Atari https://archive.org/details/amdisk-iii-3-inch-disk-drive-users-manual/page/14/mode/2up Or here: https://www.atarimagazines.com/compute/issue46/040_1_REVIEWS_AMDC_3-Inch_Disk_Drives_For_Atari.php " Switches 1 through 4 are density selection switches that allow you to configure the drives for either single or double density on boot-up. The density of the boot drive is determined by the disk installed at boot-up. These switches have no effect if the controller is set for DOS 3.0. Switches 5 and 6 determine which drive will be the boot drive. The factory setting is for drive 1, but any drive up to and including 4 may be selected for this function. Switch 7 is used when more than three drives are connected to the controller, and is particularly useful when there is a 5¼-inch drive attached. When this switch is on, the external drive will be recognized as drive 1. When it is off, the 3-inch drives are 1 and 2, and the external drive is drive 3. Switch 8 sets drives that have been selected as dual density to 256 bytes per sector when off. When switch 8 is on, it sets all drives to be Atari 1050 compatible for use with DOS 3.0. When switch 1 is on, disks with 256 bytes per sector will not be recognized."

Dogpile on the rabbit! The part number description and the crystal both say they are exactly the same. Yet The One needs to be slightly tuned? I’ll but that but the description shouldn’t be the same. Something EE wise is going on here. 🤔

Atari could have handled their finances better and tried to grasp the concept that money was not going to keep being printed on 2600 bills.

no you don't. The format wasn't even decided upon back then and Atari had enough problems getting 5.25 Tandon drives working. Apple dealt with the 3.5" drive at the time. Now Atari should have planned to release one in 85/86 yes.

what keyboard variant is this?

Perhaps this info is valid:

The original 1200/1000 had a bus header and dual intelligent SIO ports. To make it even more confusing, there were two side by side projects going on at the same time.

No love for the 1200XLS.

Bumping an old thread. Was there a final consensus on this ? I'm asking for two reasons: 1) The new 1090 boards that are being made (would it be a benefit to it to have these lines) 2) The 800XL prototypes and working samples DID have +5 on pin 47/48 as do all 600XLs.

That's a beauty! Now for revision 2.1, you want to shift all the components to the right and angle the joystick ports so you can use a standard 1200XL side plastic. 😂 Is it sacrilege to design a "reimaged" 1200XL board with a PBI header

RESET resets the computer. Sometimes people code to catch that "soft reset" and restart their game.

I suggest contacting the site owner and provide any missing content.

said link is provided in the description.

There is always the mirror site....

Freddie was “available” in 1983, every 1400/1450 used them which were all made in the latter half of the year. Some of the very early ones were ceramic.

That doesn't make sense. K doesn't have the proper(?) R/W command for the 2797. L uses a command that both the 2797 and 2793 understand.
