This similarity isn't a coincidence; [available patent documents](https://imgur.com/a/Nq35L) show that the connector was intended for some sort of never-released hard drive add-on, and recent reverse-engineering efforts revealed that the connector is essentially an IDE connector with fewer pins, no DMA signals, and an 8-bit (rather than 16-bit) data bus. \n\nIn addition, the CompactFlash standard has a \"True IDE\" compatibility mode which is (theoretically) guaranteed to support 8-bit data buses. CF cards are also capable of operating at 5V, making it easy to interface with \"retro\" hardware that doesn't use 3.3V components. As a result, this project shows that it is possible to successfully interface CF cards with the Satellaview using a simple physical adapter.\n\n## Why?\n\nSince the Satellaview's internal expansion port was never officially used, no contemporary support for any such expansion hardware is known to exist. This proof of concept is essentially a \"what could have been\" experiment, rather than an actual enhancement for any existing games. Maybe it'll find a purpose in some sort of homebrew project later on?\n\nThe board was designed around a pre-made CF breakout/adapter board mainly for ease of assembly and testing, since I still consider it a \"prototype\". If this actually manages to turn into a serious product somehow, it may eventually be redesigned to feature a CF slot directly on the board instead.\n\nYou can order the board itself [from OSHPark](https://oshpark.com/shared_projects/bJ8kBS1b); a minimum order of 3 boards costs exactly $15.00 USD.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevinacker%2Fsatecard","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdevinacker%2Fsatecard","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdevinacker%2Fsatecard/lists"}
