True! Mike, I forgot to mention that part but you're right, probably your phone call was the most effective move :-)

  If you don't get an answer I can phone him; that worked the last time people were looking for him on VCF.

    Hi Hervé,

    I received my petdisk few weeks ago, but I had to stress a little Mike aka 
    bitfixer.com aka Gubbish from http://www.vintage-computer.com and then he 
    answered at this thread: 
    http://www.vintage-computer.com/vcforum/showthread.php?38209-Use-a-PC-to-emulate-floppy-disk-for-PET/page2 
    telling us he had a lot of problems in the past months, I mean serious 
    problems: he married :-D
    I must to check if I still have his email since I didn't bookmark his 
    address, but try to contact him by vintage-computer.com forum, and if he 
    doesn't answer, write me a line and I will try to find his email address for 
    you.

    Giovi

    Hi, friends

    As Giovi is talking about the Petdisk (from bitfixer.com), I am wondering if 
    someone had (recent ?) news from the author of this interesting hardware or 
    possibly could forward me his "live" mail.

    I'm trying to order one since a big while now without success ... the only 
    answer that I had once was that he had trouble to get some parts ...

    Regards - Hervé

    Hi,


    I have not done this mod but I'm wondering which version of 1541 did you 
    use? Is it possible that the "patched" rom is for a different rom pair? I 
    can't see any reference to which is the correct part# for the ROM that 
    doesn't require changing. Did you use the ROM from the MASHUP site or did 
    you run the patch routine on your existing ROM?


    Steve

    Hi folks!

    my name is Giovi (Giovanni Verrua), italian, C= collector, I live in Brazil
    and I'm new to this list.
    As Ruud Baltissen (that should receive this post, if I'm right...hi Ruud!)
    already discovered, I'm not an hardware expert; dummy should be most the
    correct word :) so I apologize if my further posts will be silly in some
    way. I also apologize if I will do some mistakes posting to this mailing
    list. Don't be shy, correct me whenever is needed!

    My first question to this list is about the 1541 drive modified for the
    IEEE-488 interface (in other words, about connecting a 1541 to a PET), this
    one:
    http://www.zimmers.net/anonftp/pub/cbm/documents/projects/ieee-488/index.html
    also described at this page:
    http://vintagemashups.net/2010/12/commodore-1541-ieee-488-conversion/,where
    I downloaded the patched ROM.

    I'm writing this post because, of course, mine doesn't work :) - I checked
    it twice and I haven't found (yet) the mistake. I will check it again. No
    answer from the 1541 and no reset when the 8032-sk is switched on or off.

    I'm sure that:
    - the 1541 drive is ok
    - the 6522 is ok
    - the socket adapter is ok
    - the EPROM im programmed returns no difference if compared with the patched
    rom image (so I believe it's ok too)
    - the ieee cable an connectors are ok
    - the ieee-488 port of the 8032 is ok since it works fine with the Petdisk
    (from bitfixer.com).


    >>> The question for you: >>> I have a little doubt about the patched ROM:
    >>> it's showing a different behavior respect the original 901229-05 ROM.

    - with the original ROM, as usual, the floppy starts to spin and the red
    light comes on; after few seconds, the light and the spin motor go off in
    the same moment. Normal behavior for this kind of drive.

    - with the patched ROM (with or without the ieee interface) the floppy just
    spins for a while and then stops, while the red light stays on for a longer
    time (and then goes off).

    Anybody of you C=hackers made this adapter in the past, and can tell me at
    least if the patched ROM shows this different behavior?

    cheers,
    Giovi
