[HECnet] Personal DECstation 5000/25

[Ian McLaughlin]

Mark,
I've grabbed the image from you - thanks!   I look forward to seeing the patches also, once you've got slave online.

As with most hardware this age, the clock battery has died.   Unfortunately, this module is soldered to the motherboard.   The original module is a DS1287.   I have a DS12887 spare, but I can't tell if it's compatible without soldering it in.   In most cases the DS12887 is a suitable replacement, but I can't find any discussion of anyone trying in a DECstation.   Any chance anyone here has tried?

I would normally install a socket, but this module lives just underneath the CPU board, and there's not enough clearance to add a socket.   Whatever replacement goes in will have to be soldered.

Ian

This is great!   Do you happen to have the Y2K patches?   From what I have read, 4.4 and 4.5 were issued Y2K patches.

The primary date-related patch is for the 'date' command - the kernel handles dates just find, and yes you can use the 'set time to 31st Dec 23:59' and let it roll over a year to advance the date through to 2013 if you have the patience!

I've uploaded 4.4 to http://www.wickensonline.co.uk/OpenVMS/Ultrix/UltrixRiscAndUwsV4.4SuppUnsuppBootUpgradeMarch1994.iso.gz

I will upload the layered products as/when I get time.

I'm due to give http://slave.hecnet.eu a run up today which contains all my patches - I'll send another email with a link to the Ultrix patches directory. I do have the original disk so will try and find the time to take a scan of the top, but I've been saying that about the whole collection for quite a while now!

However, I haven't been completely sitting on my hands ;)
Last year I wrote a good portion of a java web application which is able to apply semantic web techniques for searching the DECUS archive. This is a great resource for code examples in many of the VMS-supported programming languages. So far I have classified most of the VMS-specific file types using the Java 7 custom mime-type hook and am now able, for example, to search for DCL files within the DECUS archive for a specific lexical call. My plan is to extend this to system library calls for all common calling standard languages. The cataloging side is done I just need to add some umph to the results (hyperlinking everything together).

Regards, Mark.
