Hi everyone, hope someone has an idea to help.

Ok, I went to a hamfest and bought a 286-10,
fellow said it worked good, brought it home and
it doesn't work.

found that either the motherboard and/or the 
memory chips had been changed, when it is turned
on, get 1 beep followed by 3 beeps, according to
my book, there is a parity error.

I do not have a copy of this board, I didn't get
 book, I think it
is an early 286 or at least it is different from the
board shown in the Sams troubleshooting manual.

The memory chips are km4164b-12

There are 4 rows for 9 chips, d-0 to d-7 and one
blank (I assume this is for parity)

I have a total of 18 chips available, but just 
wanted to get it running with 640k if possible.

The cpu appears to be MB654304U, by the way, 
I have had some discussion about whether the 
battery has to be in unit (It is missing in this one)

I bought this for my son who just started at DeVry,
and I would really like to fix it so he can get on 
the net.

Any help would be appreciated.

thanks
