I recently purchased an AT&T 6312 motherboard and am trying to
install it in a Xerox 6070 (AT&T 6310/Olivette(sp?) ) computer.
Other than the fact that that certain cpu related chips are -12s
and that the 1 meg of memory is not socketed, the boards look
identical.
I bought the board as is, so I do not know if it works or not.
Symptoms follow:
1) no video - screen has raster. Computer equipped with color monitor,
indigenous video board and a Display Enhancement board (DEB)
2) LEDs on mother board indicate error 6B.
3) computer does not boot (of course).
Questions:
1) Are the bus board and the indigenous video board the same for the
6310 and the 6312 computers ?
2) Should I be able to exchange just motherboards for a 6310 to 6312
upgrade?
2) What does error "6B" on the LEDs mean ?
3) Any constructive suggestions ?
Any help would be greatly appreciated.
Thanks.
