Hello,
I have re-captured the schematics, since all I could find on the web were many copies
of the same poor scan. Couldn't read chip numbers, pin numbers, or resistor values.
I did not capture the power supply section. PDF's on my web site tauntek.com,
on the Matrix 1000 firmware page. Let me know if you find any mistakes and I will correct them.
