This is difficult, since AT&T no longer supports the machine. The only remaining possibility appears to be ``A Small Computer Repair Company'' (ASCRC). They will diagnose your problem, and repair or replace the part that is broken. They will try their hardest to repair the item first. You need to send the computer (or just the component in question) to them. They will repair/replace it and ship it back. Their turn-around time is usually 48-72 hours. They repair AT&T's 6300, 6300+, 7300, 3B1 and UNIX PC computers. For more information and/or to arrange servicing, contact:
A Small Computer Repair Company 5762 Dichondra Place Newark, CA 94560 (510) 430-9226 or (510) 793-6980
