6802/6808

[paddythegreek]

What is the difference between a 6802 and a 6808 chip, if any. Can a 6802 be substituted for a 6808. Thanks Ken

Lost me at 6802

As I understand it the 6802 should replace a 6808 but not the other way round I believe.

6808 doesn't have the onboard ram that the 6802 has. Best check the data sheets for both and do a pinout compare

Just to hear of those chips being mentioned brings back memorys.
I'm getting old.

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.

Thanks for the replies. I too am old.
Found this link this morning which explains a lot. Might help others.
