Running NEXTSTEP 3.3 PARISC on an HP Apollo 9000 Model 712

5. September 2009, 21:57

A few years ago I bought this nice small PA-RISC machine made by Hewlett Packard in the early nineties on eBay….. It is an HP Apollo 9000 Model 712 and had HP/UX 10.20 preinstalled but I really was interested to see it in action as an alternative to a NeXTSTEP Box…

My HP 712 Box has the following configuration:

  • PA-RISC 7100LC 80 MHz
  • 64 MB RAM
  • 2 × 2 GB Harddisks
  • Video-RAM expansion

here is a very detailed description of its architecture …

Let’s take a look inside:

Here is HP/UX 10.20 in action:

Although I also had the NextStep CD needed for installation and the CD even booted on the machine – it got stuck somewhere – as can be seen here:

After some reading e. g. here , here and here

I realised, that my SCSI CDROM – a Teac RS56 – was not capable of a certain feature, namely to read 512 byte sectors instead of the usual 2048 byte sectors.

If you see the following error message (“request timeout…”) you have the wrong CDROM drive…

I finally found a list of old CDROM models which should be able to do so and recently bought an Apple CDROM 600i off eBay with the hope that it would let me set a “jumper” to enable the 512 byte sector mode.

Well it did not have such a jumper but I nevertheless tried to install NextStep again – and it worked!!!

This is the result:

Now I’ve got a nice Nextstep workstation which runs Nextstep flawlessly and is surprisingly fast while doing so! I know this because a few years back I bought an original Next box from a fellow student which turned out to be the black and white 17 inch model and it was quite slow altough it is supposedly faster than NextStep Cube with its 16,7 Million colours…..

Unofficial Aging Tabs - Firefox Extension

28. July 2009, 23:56

Unofficial Aging Tabs Makes unused tabs fade with age and highlights the selected tab – and more!

This extension is based on Aging Tabs 0.7.1: created by Dao Gottwald

This is useful if you always have a lot of tabs open – you can see at once which of those are not so popular and may decide to close them.

I extended this extension to automatically close the oldest tabs and even bookmark them with a specific tag so that you can get back to them later!

Some screenshots:

Retriever for Marvin 0.3.1

29. July 2002, 11:53

Well here is Marvin’s Retriever. Mhmm. What is there to say. He has been programmed for the Presentation Manager of OS/2 and more or less does what he should.

Marvin’s Retriever is a download helper application similar to Netscape’s Smartdownload but not as powerful yet. He is able to fetch Urls from the clipboard and to pause and resume download jobs. He is also quite informative about the condition of the present download. And that is about it already. This isn’t too much, and the real job is being made by GNU wGet because this program has proven to be quite reliable and because I didn’t want to spend too much time writing this small utility.

Here are some screenshots:

IBM OS/2 Warp 4.0 or higher, eComStation 1.0 or higher
