800XL and 65XE (which I have already done), just missing the 'help' function key on the side. The pins were in a different order again, so that's now at least four different pinouts for these 8-bit Atari keyboards, the 400, 65/130XE, and at least two different one for the 600/800XL.
Another keyboard conversion done and off to it's new owner for whatever project they have in mind, and my Atari 400 gets it's keyboard back, now fully tested.
If you want to order a kit to convert an Atari 400, you can buy one below. The kit include the USB keyboard controller, mounting pillars and a USB cable. You just need to supply the Atari 400.
