Uzebox minimal design. The goal - to creat reprodusable modular design with minimal set of components. Original project is located at http://uzebox.org
Update 16-Oct-2014 (2): Created simple MIDI expansion board. Never tested, since no MIDI devices owned :). See readme.txt inside midi subdir. Actually project finalized.
Update 16-Oct-2014: Added video extension for AD725, same structure as in other projects (eagle,schematics,toner-transfer). Also untested version removed. Currently version is fully tested and confirmed working.
Update 13-Oct-2014: Added SD Card adapter. eagle - To be opened with Eagle Cad 7.x. schematics - Schematics, top jumpers and placement. Also an example of microSD adapter soldering. toner-transfer - Ready-to-print file for toner transfer. Have fun! For best results: Non-SDHC cards. In case using 2GB cards or bigger, create first partition about 256Mb. This is more, than enough for UzeBOX roms. Most important part partition should be FAT16 with 16K clusters.
Update 04-Oct-2014: This version is fixed somehow and soldered. Appears to be working. Files (in mainboard dir): eagle - To be opened with Eagle Cad 7.x. schematics - Schematics, top jumpers and placement scart - connection via SCART toner-transfer - Ready-to-print file for toner transfer. Have fun!
Update 01-Oct-2014: Current version is NOT tested in a "wild". Placed to share with forum members. Files (not-tested dir): *.brd and *.sch - To be opened with Eagle Cad 7.x schematics.pdf - Schematics board-bottom.pdf - For toner transfer. Must be validated for correct size after/before print. Please check schematics/board layout for jumpers on top.
