(DIY) SUPER SALT DIAGNOSTIC CARTRIDGE FOR ATARI 800XL

Hello,

This is a tested and working circuit board. This cartridge is tested with Atari 800XL

This is only cartridge part of diagnostic tests. some of diagnostic tests need extra hardware.

You can download some sample EPROM images from this link:

https://archive.org/download/super-salt-roms/SUPER_SALT_ROMS.zip

This cartridge can also be used as generic 8KB/16KB Atari 8-Bit Computer Cartridge.

You can find many different ROM files from internet by searching "Atari 800XL ROMS" or "Atari 800XL tosec"

You should duplicate the ROM file reaching to the size of EPROM capacity with using a "HEX Editor" program. EPROM must be fully filled.

This PCB design is based on Joe 'Kingpin' Grand's Atari cartridge schematics. Many thanks to Joe 'Kingpin' Grand.

COMPONENTS:

27c512 (W27C512) or 27C256 or 27C128 (DIP28)

74LS00 (DIP14) (74LS00 is only required for 16KB ROMs, not needed for 8KB ROMs.)

100nf Ceramic Capacitor

DIP28 WIDE IC SOCKET (optional)

DIP14 IC SOCKET (optional)

You will need a programmer for EPROM

Please choose: Edge connector YES and Bevelling Yes (45°)

In order to protect your electronical devices, always turn off your ATARI before inserting or removing cartridges.

Gerber files can be changed at any time. Before paying for the PCBs, be sure to update your orders!

If your programmer have capability to test IC chips, like 74LS series, then you should not forget to test them before soldering, some chips may have defect. (TL866 Minipro Programmer is able to test some of logic IC)

As you can see I have uploaded many projects and I am still working on new projects. If you have any questions, please look for answers online. Unless I specify explicitly, all my projects are tested and confirmed to work under normal circumstances before being shared. I'm sorry I didn't have enough time to answer all the questions.

Use this PCB at your own risk !

Have fun

Thank you.
