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
