I'm sorry to report that Ken Boak died recently. As posted elsewhere he was active on many forums and interested in many kinds of CPU, both historical and homebrew, and interested in projects from transistor to FPGA based. More at the link.

Here's a search returning his threads here - he did of course also contribute to others.

He'll be missed.

(Thanks to Gordon/drogon for the newsflash.)

I'm sorry to hear this news. The link to his posts show a willingness to share information and be useful to others in the hobby. That's a fine legacy. Michael
