Check out the video.

Note that this is a first, as Woz never tested a 6800 in an Apple 1. He did do some testing with the pin compatible 6501 in his prototype.

Congratulations on making it work!
I wanted to try it too for a long time, but I did not get my Mimeo-1 built yet.
I missed being the first here
Great work Mike! I was always curious if this would ever successfully run 6800 code.
I'll bet Woz himself would be interested in your success. Well done!
It wasn't me. It was a collaboration between Eric Smith writing the 6800 monitor a while back and a friend from down under named Lionel doing the hardware debug. Woz already knows about it.

Absolutely COOL!
I updated Eric's MESS patches from 143 to 146 and posted them along with the ROM source and binaries here: http://asciiexpress.net/files/Apple-1_6800/. I was having problems with MESS 143 on my Mac, hence the update. At the time 146 (6 months ago) was the current release of MESS (now it's 148). I also included a small benchmark (Pi to 1000 digits) that I wrote to compare performance.
I would if possible like to benchmark the real thing to validate MESS performance. A video of the run would be most helpful. Runtime with output is about 2 minutes.
Thanks.
