S100 68K issue
Wondering if people have been using the 68K board. I think I have timing issue because pWR* is going HI at the same time the data is being released. You can see this in attached LA capture. I think that is why I am not getting characters from the prop console and probably explains why I have not gotten reliable data from the IDE card either. The dual serial card and memory work just fine. I have tried different clocks as well - this one is at 2MHz so that should not be the issue. Was wondering if someone had seen this and resolved. I will dig through the schematics and the Wilcox book as well. I think once I have this resolved, I can get CP/M 68K going.
Thanks in advance
