Build your own MyIDE

 

Copyrights:
 MyIDE (home-brew units) is for personal use only and you are not allowed
 to sell them commercially without my license.
 I own all the rights of this IDE-product and resulting software/drivers.

If you can get your hands on 74F04 and 74F32 instead of the LS-types, do buy them. The F-types give 99% compatibility with IDE-drives. With the LS type you need to find a drive that works fine.

New version (3.1) on this page. Now it works on more drives! If you made the version 1 or 2 interface, please change the IDE-connector pins 4,6,8,10,12,14,16,18 to: not connected, add a 4k7 Ohm pull-up resistor to pen38 of the IDE-connector, use a 220 Ohm resistor for a activity-led.

On this page you see the schematics, example and wire-layout (component-side) to build your own MyIDE-interface. The print has 17 connections you have make. 16 wires go inside your Atari XL/XE or onto a empty cartridge. The print out the pictures: Right click on the picture and select print.

Just drop me a line when you need help.

Use Right-Click on the layout, save picture, print it out the way you want it, and start building!

Where to put the components (pin 1 is always bottem left):

  • IDE-connector; Top

  • 74LS245; Left

  • 74LS32 or better: 74F32   ; Middle

  • 74LS04 or better: 74F04   ; Right

  • 4.7k Ohm resistor to connect 17 (IDE-connector pen 38) with 2

  • Optional LED; IDE-connector pen 39 (N.C. in layout) ---<|-- 220 Ohm ---2

Where to connect the 16 wires inside your ATARI XL/XE:
All wires except one are directly connected to the Atari 6502C-CPU. In a XL its ID is CO14806-xx placed in the bottom-middle. In a XE its ID is CO14806C-xx and found in the top-middle. One connection is made to the (only) 74LS138 found on the PCB. In the XL close under the cart-slot and in the XE left-above CO12294.
