I picked up a "dead" Commtech K7TA-H for free. Popped the CMOS battery out for a bit, popped it back in, added a 1.2Ghz Athlon MP in the Socket A, stick of RAM, olde AGP video card and POST card and hooked up a power button.
It's a-liiiive! Unfortunately Commtech is one of those #%%@##$ companies that eliminates all info about their discontinued products. (The olde "Pi$$ off! Buy our new stuff!" attitude that makes me NOT want to buy from a company.)
I found a link to a PDF of the manual on some bare bones computer site (no updates since 2005) but all that downloads is a 300+ kb file that's completely blank. (How can a .PDF with no text and no pictures be over 300K?)
I also found with the Web Archive an old page from the Commtech site that showed the front panel connector pin assignments. Unfortunately the Archive got none of the FTP downloads. I got the last BIOS (1.5) from a ZD.net site in Germany.
That'll help but still no clue about the USB header or any other jumpers not marked on the board. Seeing how weird the FP connector is laid out, who knows how the USB header is configured.
