Had fun tonight using the four channels of my Siglent SDS 1104X-E oscilloscope to monitor multiple pins of the 6502 CPU from my Atari 800XL. Fun to see in action! https://atariprojects.org/2025/01/01/use-a-multichannel-oscilloscope-to-test-multiple-pins-of-an-integrated-circuit-simultaneously-15-30-mins/ #atari8bit #retrocomputing #atariprojects

Fixed an Indus GT floppy disk drive for the Atari 8-bit computers today by replacing the track 0 sensor ($5 part) https://atariprojects.org/2024/12/07/replace-the-track-0-sensor-on-an-indus-gt-floppy-disk-drive-for-the-atari-8-bit-computers-30-60-mins/ #atari8bit #retrocomputing #atariprojects

Did you know that the Sys-Check II device can test the RAM & ROM of an Atari 8-bit computer even if it won't boot (i.e. dead test) https://atariprojects.org/2024/11/16/purchase-the-sys-check-device-for-diagnostic-testing-the-ram-and-rom-of-atari-xl-xe-8-bit-computers-5-10-mins/ #atariprojects #atari8bit #retrocomputing

Here is a relatively simple project that adds S-video output to an Atari 800XL by soldering a single wire to connect the chroma signal to the 5-pin DIN https://atariprojects.org/2024/11/07/connect-the-chroma-signal-to-the-5-din-video-jack-of-an-atari-800xl-for-s-video-output-1-2-hrs/ #atariprojects #atari8bit

I made some videos of the oscilloscope waveforms for each of the 40 pins of a working 6502 Sally CPU on an Atari 800XL. I hope this helps others see what is expected on a working system. https://atariprojects.org/2024/10/19/troubleshoot-the-6502-processor-on-your-atari-8-bit-computer-circuit-board-using-an-oscilloscope-15-30-mins/ #atari #atari8bit #atariprojects

I published several posts this weekend on the Atari Projects website on tools for repairing 8-bit computers. Covered are multimeters & oscilloscopes, desoldering irons & hot air guns, and other useful items https://atariprojects.org/ #atari8bit #retrocomputing #atariprojects

Started some posts on Atari Projects about getting started with fixing 8-bit computers.
