DOS-73 Board Memory Exp Board

[R.HERBST]

I have tried to install a DOS-73 Coprocessor
and a 512 KB expansion Board and have experienced
difficulty trying to use both at same time.

Either one will work in slot 3 (slot on right side)
alone, but if I try any other combinations I get either
a Panic Error (with mem exp in slot 2 & DOS in slot 3)
or it just will not recognize the memory card or Dos card.

Any similar experiences??  Suggestions??

I have had our friendly AT&T service people try
3 different System boards (1 meg), same results!!!

Thanks,
