Anyone have any thoughts on whether those data signals look right?
Thanks Rob From: Rob Jarratt [mailto:[email protected]] Sent: 27 July 2017 21:18 To: General Discussion: On-Topic and Off-Topic Posts ([email protected]) <[email protected]> Subject: DECstation 220 Impasse Reached Hello Everyone, As I have mentioned before I have made some progress on a DECstation 220, but I have reached an impasse. I get some signals on the data bus which I am not sure about. They look odd, but they could be normal, I just don't know. I took a picture of the scope trace, which is here: https://rjarratt.files.wordpress.com/2017/07/decstation-220-data-signals.jpg . Any advice on whether that looks like a "normal" signal? If anyone is interested, I have posted more details on general progress in this blog posting: https://robs-old-computers.com/2017/07/27/decstation-220/ Thanks Rob
