No I won't. I just had a flashback, sorry. The PWA has to be portable. Carrying an old CRT with a composite input would not be feasible or safe. However, if I were to build in a simple waveform capture into the PWA project (a simpe O-scope), it would be nice to see the details on a larger screen once I got back home with the data.

Jeez, that sorta makes me worried. I was hoping these IC's would be unused. If they are used, I would hope they would be tested. Thanks for the link... BTW the debit still has not posted a full day later...

It's not about how fast a person can read, but how fast the screen updates while scrolling or full-display redraw. A 1MHz 6845 while rendering text will be just on the edge of acceptability...
If I were to use a 6845 again, I would use a dedicated slow 65C02 to control and display the video RAM and a faster CPU to directly access the video Ram... There are guys here that have done this already using Phase 2, I've read some of their posts before, but I'm not ready for it YET.
This would be a whole new project, but I was excited to see the IC for sale, so I scooped some up. It's sorta of dismaying that I could be buying used parts, not only that but I won't be able to test them until I put them in use....
