About me

Hello and welcome to my vintage computing blog!

My name is Rudolf Brandstötter, I’m from Austria/Europe and I collect vintage computers. I collected so far more than 700 different machines from all over the world. I also do troubleshooting, repairing and actively use my machines.

With this blog I want to documentate parts of my work.

This is a (partial) list of the systems I have:

      Hello Zsolt:

      On the Vintage Computer Forum website there is a section dedicated to old CP/M computers, including the Osborne. I’m sure someone there has software for the Osborne 1. Try posting your request for information about software at the Vintage Computer Forum CP/M Section.

    Hi, I have two profile hard drives (one 5mb, one 10mb) both working just fine (I have owned them since the mid 80’s). I was wondering if you had any advice on how to keep them in good working order. Are the bearings prone to failure from sitting unused? Is it best to run them occasionally? Any advice is appreciated. I really like your dedication to the Lisa. I am fascinated by that machine. I run my profiles on an enhanced iie. I hope to get my hands on a Lisa someday.

    Your collection is amazing!

    I’m a librarian at Université du Québec à Montréal and I’m working on a little exhibit about the inception of the Macintosh computer. There’s a part of the exhibit where I would like to put a picture of an Altair 8800. Can I use one on your Web site or a print screen from your youtube video? The exhibit is on campus (in the librarian), not on the internet, freely open to the students. faculty staff and other patrons. I would of course cite your site or video.

    I need to have a written permission. For that reason, if you agree with my request, I would prefer you email me rather than reply to the post.

    Hi – just came upon your website, and admired your remarkable collection. A question for you – I happen to have an old Apple Fileware “Twiggy” disk from the original Lisa. It’s in its original box, and is unbent and in apparently good condition. It’s been in a desk drawer for ages… Could you use it? Let me know.

    Thank you for a very nice site! Since you are both Austrian and very clearly a serious collector, can I ask you the following question?
    A few months ago I bought a very nice 6502 system, an es65 rack-mount computer. Apparently made by Ing. Ernst Steiner in Vienna around 1980, but I cannot find any information on the machine… Would you know any more details?

    Kind regards,

    I’m really impressed by your collection !

    I recently bought a PET 2001 and I have no software 😦
    Could you please send me some .wav files to feed my pet ?

    I would be very grateful.

    Kind regards,

    Rudolf Brandstötter, love your vintage computer web site! I own a fully operational Apple Lisa 2 computer (3.5 diskette), (3) Apple ][e computers (one from high school) with hundreds of games and working on restoring a Macintosh Portable laptop. To restore the Apple Lisa had to purchase two computers for parts which includes the 5MB external storage case and mouse.

    What is your e-mail address please?

    Warm regards,
