LX.NET Posted August 16, 2015 Share Posted August 16, 2015 (edited) For those of you interested, I did a first attempt at a video showing the Howard/Howdy device in action. Feel free to comment. https://www.youtube.com/watch?v=0lcEOnTPs2w Edited August 16, 2015 by LX.NET 6 Quote Link to comment Share on other sites More sharing options...
StijnDW Posted August 16, 2015 Share Posted August 16, 2015 Interesting video, the debugger software looks to be pretty powerfull. To bad the lcd display has issues. The pixel clock for the "a" part looks to be bad. The other parts also look bad don't know if that would be software related. Maybe another (data?) line also has issues. Question of course is what causes the problem Bad connection in the glued connector (most likely) Lcd gone bad Something on the board gone bad It might be repairable, but I wouldn't feel confident toying around with such a rare piece of equipment.

I did open up the Howdy once and carefully fiddled with the LCD connector. The left third did show correctly then. So it might simply be that bad connection. Once I managed to get a good screen with the actual blue background and yellow numbers for the math demos. My best guess is that the ritual is not as simple as I am doing it now. Still working my way through the Epyx documentation (again). For the Pinky/Mandy you need to load a bootstrap monitor program first. Howard does not need that, but it might need something to do the proper initialization of the hardware. I'll contact Harry Dodgson again and ask him. Already did a while ago, but he might have missed it. I'll gently nudge my questions in his PM box. Edited August 16, 2015 by LX.NET Quote Link to comment Share on other sites More sharing options...
LX.NET Posted August 16, 2015 Author Share Posted August 16, 2015 BTW, I might do another video on the Handebug tooling once I know how to use it a bit better. I do know how to do the Step functionality and read the bus data. Here's something I wrote a while back on the Pinky/Mandy kit: https://atarilynxdeveloper.wordpress.com/2014/05/16/epyx-development-kit-part-2-pinky-and-mandy/ Quote Link to comment Share on other sites More sharing options...
