Best check the data sheets for both and do a pinout compare

Click to expand... So am I. If it's relevant, the older Williams cpu boards can use either of these processor chips. With a 6802 fitted, then provided the internal ram is enabled (by a jumper change, AIR), one of the 6810 ram chips can be removed.
