Design your own Homebrew TMS9900 microcomputer in TI-99/4A Computers Posted January 11, 2015 Some time ago I designed and built a TMS9900 system and then Single Board Computer based on the TMS99105. I finally got around to documenting it. I have made the TIMON listings available and circuit diagrams and hope to put up all the other software as soon as I can. I'd be interested in your thoughts. http://www.itech.net.au/tms9900 Alex.
