Atari 6502C Sally EXT Ground Plane
Kaczorowski Sep 17,2024
Atari 8-bit computers, including models like the 400, 800, and XE series, were produced in the 1970s and 1980s. While many enthusiasts still use them for gaming and expansions today, newer models face stability issues due to cost-cutting in the design, particularly the lack of a ground plane, which makes them more prone to interference. This interference can affect screen quality, especially on Atari XE models. Specialized sockets have been developed to add a ground plane and address these stabi...

6502 to 8501 adapter
Bartkowicz Aug 20,2024
Commodore Plus4 CPU replacement - for all of you having a bad one and not wanting to butcher C64 for thisIt uses NMOS version of 6502 thus it is able to execute all illegal op-codes as original MOS7501/8501it also features up to 512k of Heyness compatible memory expansion that few software titles use and provides 64k of base ram, even if installed inside Commodore 16 (you need to disable original DRAM chips in order to use it)https://www.youtube.com/watch?v=1e0n6eZzYc4
