Read More…This board is inserted between the GTIA chip and its socket in one of the Atari 8-bit home computers. The FPGA on the board listens to the digital communication between the GTIA and the rest of the system and re-generates the video output in a near-digital form. This output signal (we call it 'lumacode') can then be flawlessly upscaled to a pixel-perfect HDMI signal using an RGBtoHDMI device or something with equal capabilities.
The original video output of homecomputers of the 1980th is of pretty low quality. Using a modern TV to display this signal normally does not make this any better. In fact it normally just exaggerates the visible noise. Also there is basically no way to improve the analog signal because of the random nature of the noise.
With my digital-only approach, the monitor picture is absolutely perfect without any noise or ghosting.
The board should work with all variants of the Atari 8-bit machines that have a CTIA/GTIA video chip.
Boards shipped since 29.9.2023 have the firmware version 1.1 that fixes a display issue with the "Atari Control Picture" program. I know of no other program that did not work with the previous version already.
Starting with 22.3.2024 all boards are shipped with firmware version 2.0 that fixes some additional minor incompatibilities with GTIA display modes.
I do not ship to the UK any longer. Please refer to the official vendor list for information on how to obtain my designs in the UK.
