Otrona / Hospital

I was not able to get access to any of my notes to more completely answer Eric's question. Short answer: NO. Otrona did not have two different obscure numbers of tracks for their disk sides. On the limited number of Otronas that I encountered. What I encountered was very straight-forward

RE: H7861 PSU issues

I rather cut the story short, I did repair the damage and had the PSU working again very briefly, but something else failed somewhere and it just does not work correctly. Regards Rob > -Original Message- > From: cctalk [mailto:cctalk-boun...@classiccmp.org] On Behalf Of Noel > Chiappa

RE: H7861 PSU issues

In my case the PSU where I had this still does not work. It is a H7140 from a PDP-11/24. I found the failed 555 after help from a list member, but when I replaced it and powered on there was a big bang (I should have told you that!). I have never been able to repair this PSU and I need someone who

Re: H7861 PSU issues

Thanks! It was very satisfying and not the worst thing to go wrong for a beginner. I was also quite surprised that such a simple component would die, and what I find more confusing is that it died while I was using the machine. Aaron. Noel Chiappa via cctalk wrote: >

Re: H7861 PSU issues

Picked up a few 555s and sockets and now it works! I am very happy. Going from not knowing how switch mode power supplies work, to watching some YouTube videos, and then finally being able to debug the problem and fix it was a lot of fun. I wonder what will die next. Thanks, Aaron. Rob
