Does anyone have some good hints on what and how to replace them? I have a CDC 8 inch floppy drive with a missing pressure pad. Tried to put some half a millimeter felt cloth with some double adhesive tape to replace it. But it didn't work very well. If I gently pushed the upper pressure pad arm it started to read at least. But it looks like it is possible to over-do it. I added more padding and then it probably got too thick since it now failed again. I guess that if there is a bit too much pressure the signal might be too high in the input amplifier leading to distortion? What is the best pressure pad material and what are you usually replacing it with? /Mattis

I beg to differ with HP's recommendation (in their doc set) for Devin'ssituation.? HP's description is meant for customer sites to have a copyof usernames/passwords to which they can revert for nasty situationssuch as a corrupted SYSUAF.DAT.? *If* this system has the 'alternate'file, it should have the same problem as the original, of unknownpasswords.? What Devin needs is instructions to break into the system. I happen to know how to do that (used to work in OpenVMS Engineering).Is that something that should be discussed here? Thanks,Dick

Soldering DB connectors

by rsmilward＠frontier.com

Something that's always worked for me: when soldering a male DB connector (DB9, DB25, whatever -- or really any male/pin style connector), plug it into a mating female connector first. That will hold the pins securely in place and prevent them from sagging in the plastic of the body if your soldering iron is too hot or you hold it on too long. -- **Richard

Way off topic: posting to the list using default Samsung Android Mail Client

by cctalk＠ibm51xx.net

I am wondering if anyone else has tried using an Android Phone (a Note 10 in my case) with the default Samsung email client to post to this list? Whenever I post, even though the message is correctly formatted on my device, all the CR/LF are removed from my messages. See below for an example: ------- > Can it still be registered?>Is the Author find able? Do he still have 8" floppies? > *** Will it NOT be lost in the mail with COVID 19 ***A deep googlefu might find the author... just saying...;) ------- However, when I sent it, it looked like this: > Can it still be registered? >Is the Author find able? Do he still have 8" floppies? > *** Will it NOT be lost in the mail with COVID 19 *** A deep googlefu might find the author... just saying...;) Sending from trusty old Outlook 2007 on Win 7 works fine with the list and emailing people back directly from the phone seems to work fine as well. It is only when I am replying to the list that the issue occurs. Any ideas/suggestions? TIA! -Ali

Microvax 3100 VMS 7.3 password reset.

by lyokoboy0＠gmail.com

I picked up a microvax 3100 this past weekend from a office that was shutting down. I was able to start the system up, it boots up to a login prompt for VMS VAX 7.3. I do not have any login info for this machine, is there a procedure i can follow to reset a password to an account? Image of system : https://i.postimg.cc/43bG0nSx/20201111-090018.jpg

Wanted: PDP-8/f or m (with or without cards)

by mosst＠SDF.ORG

Hi All, I'm looking for a PDP-8/f or m. At a minimum I'd like the chassis with PSU, front panel, and backplane as I already have enough spare OMNIBUS boards to build up a basic system, although I'd still be interested in the boards if you have any. Depending on the configuration and condition there's a few things I'd consider trading, namely my PDP-11/34a, AlphaStation DS10, Intel MDS 231, and KIM-1. If the price it right I'd be happy to buy it too. I'm in the UK but would be prepared to ship some of the systems internationally; I can build crates and such.

I was thinking about firing up the old (late 80s?) drive I have in storage and trying to image the carts I have. What should I watch for? Any typical failure mode? - John
