Exam doesn't seem to work

Greetings,

I've built the amazing pidp8i, and it works perfectly except for one thing. When I press the Exam button, the PC and MA registers advance as expected, but the contents of the address being examined are not displayed in the MB. The MB just sits there displaying whatever was there when I stopped the computer.

Since everything else is working, I must be doing something wrong. Help!

Are you using the latest trunk or the binary images produced over a year ago?

If the latter, I believe you're running into a known bug which is fixed in the current version.

We're edging towards a release, but since this is all happening in our spare time, you probably should update in place rather than wait for new binaries. It would be better to have your testing and feedback before release rather than after in any case. :)

Thanks. That fixed it. And thank you for all the work you've put into this project. The incandescent effect is amazing.
