1450XL Replica PCB

Description

Following the lackluster sales of the Atari 1200XL 8bit computer, Atari began work on a replacement series of computers. The idea was to include additional features that Atari hoped would spur greater sales and modernize the 8bit line. To that end Atari developed a 14xx series that at each step up included additional features, a base unit with builtin speech and modem capabilities to the high end unit with dual 5 1/4" floppy drives builtin. But computer time sped up and development delays forced cancelation of the 14xx series. Only a few pre-production pcbs and engineering units survived. Cut down versions with cheaper parts were finally released as the 600XL and 800XL.


Only build this board if you are serious about finishing it. There is no case at this time that fits this pcb and it is expensive to purchase parts for. I intend to redesign this version to fit a 1200XL case with more modern parts, no modem or RF out and hopefully additional features.

Tips

This board is a replica of the pre-production Atari 1450XL version. As such it will have the limmitations and incompatiblities inherent in a not quite ready for primetime release. Currently with this version most external PBI devices are working, but not everyone is guaranteed to work. This is Youtube video of the current tested functions of the board.

1400XL Specific Carts

Description

This section is about the current only specific software for the unrealeased 14xxXL line of computers. It consists of a SALT cartridge to test various features of the 1400XL computers and a very basic terminal program that uses the speech chip to provide feedback on the progress of the communication attempt. I have two basic versions of both to fit various styles of cartridge shells, currently a version of AtariGeezer's mod of a split 8K game cartridge and a replica of PixalPast 16K cart design. Currently both come in pcb forms for the AtariMax, AtariBrown and XESuper cartridge shells

Tips

Both files contain BOM, Schematic, ROM files and Gerbers for the various styles of cart shells. They are generic, meaning for instance any style AtariGeezer modded pcb can be used for either the SALT cart or the TELE cart depending on which ROM file you use
