I recently got an Osborne 1a, which needed a lot of cleaning and had probably been stored
in a barn for some time. After getting the drive parts to move freely again and removing a
blown cap on the power supply, the machine will start up and the screen is green, although
it's just showing some random characters. I understand from someone's advice that
some RAM may have gone bad. At this point I'm not sure if I should continue to try to
get this going, or just resign it to someone with better resources for diagnosing the
issues. If anyone has some advice for moving forward with this, I'd be interested to
listen. Some context: this is my first such restoration endeavor. Thanks - Steve

 Hi all,
 My 11/73 restoration has got to the point that I am loading stuff from RT11 backups, and
I have a lot of Saturn-calc and wp data that I would like to see again. My licensed copy

 I downloaded some RX02 images posted by Mark Matlock, but the disks appear to be all

 Does anybody know of a source?

 Nigel,
     I’ve been trying to find a working distribution for PDP-11 Saturn-Calc and Graph for
some years now. I had a licensed copy many years ago for RSX11M but it no longer works. I
do have a working copy of Saturn-Calc and Graph (but not WP) for VMS on my MV3100-80 but
not the VMS distribution.
     I have managed to contact the lead programmer that developed Saturn’s software
through a former president of the company. The programmer believes he has a copy of the
source code for PDP-11 and VAX on a CDROM that is in a storage unit. He has retired
overseas and come back home where the storage unit is a couple times a year and I’m hoping
he can find the CDROM on his next trip back. I can keep you posted on our progress in
trying to recover this software. It helps that the programmer is interested in making the
Saturn products available as it may need to be recompiled or at least relinked to be
compatible with the newest versions of PDP-11 operating systems with Y2K etc.
      We thought we had it recovered a couple years ago when nine RX50 floppies were found
in Australia that were from a distributor that could be used to generate new customer
distributions, but there was no documentation and some info was missing. Also, manuals for
the Saturn products have not been scanned so we are looking for them as well.
      If you had some specific Saturn Calc spreadsheets that you wanted data extracted
from, I might be able to help you with my working VMS version of Calc. Saturn Calc was a
great product that we used a great deal back in the day. The Saturn Graph product
supported VT340s with the mouse and could generate plots a wide variety of HP and other
plotters, printers, etc.
 Best Regards,
 Mark

 This may be a larger conversation than I intend but how would you all
 generally start if you ha backup tapes that you wanted to try and
 read/restore?
 Supposedly they're Amiga qic tapes. I'm a little worried about the
 structural integrity of the tapes. Not knowing what software was used,
 would this be a literal job for something like tar via a Linux system? Then
 see if I can interpret the dump and sort out files afterwards?
 I might see if a local group wants to help play with this effort since I
 think I only have 1 drive in unknown condition.

 THere were certain tape manufacturers and plastic/metal clip marks and wear
 patters that were typical of certain types of drives reading certain types
 of tapes.  Maybe high resolution photos of a few used tapes will reveal
 clues.  A tape ejected 30 times will have certain patterns of wear in
 certain places.  I have lots of different types of tapes, I am happy to
 compare your used tape photos with anything I might have that would be
 similar.
 Not a guaranteed solution, but it might help narrow down candidate systems.

 It is unlikely that the tapes are in tar format, so tar on Linux won't
 help.  The chance that they are in tar format is much higher if they're
 from Amix (Amiga Unix) instead of AmigaOS.
 There is a better possibility that the tapes were created by BRU since
 AmigaOS 2.x (and maybe later) included a version of that.  BRU is now
 Argest Backup, if you need to go down that road.
 It is also possible that the tapes were created with any of the many
 third-party backup applications that existed for AmigaOS.
 In any case, using dd (not tar) on Linux to copy the tapes to disk to
 "interpret" and "sort out files afterwards" is at least a starting
point.
 Other list members are better qualified to comment on the physical
 aspects of doing that without destroying the fragile old tapes.

 Heck, I'd just unspool a bit of the stuff, drop some Kyread on it and
 have a gander with the old microscope.  That can at least tell me how
 many tracks are involved.
 But being a quarter-inch cartridge leaves a lot of ground open.  For
 instance, what if these tapes are Iotaamat-formatted?  A regular QIC
 drive will have nothing to do with them.  There were other manufacturers
 (Cipher 525) comes to mind that do not use standard formatting
 techniques.  On some of the later 8mm Travan carts, the tape is
 will-o'-the-wisp thin.
 FWIW,
 Chuck

 I went to Onyx2/Origin 2000 training in Mountain View in the building that
 is now the Computer History Museum and I met a lot of Gov folks but I also
 met a lot of oil people who used SGIs to crunch data. At the time no one
 could touch them but that too changed
 As for workstations the one I remember being a real competitor was
 Intergraph. They had dual pentium pro boxes with proprietary cards that ran
 NT and Softimage. Microsoft bought Softimage to compete with SGI and SGI
 bought Alias Wavefront

 Wow, I have a dsm11 disk image there too? Weird. And the XT Tool kit

  I remember having to do something like that some years ago. If the ASCII file isn't
too long and you can manage with manual edits, you can load the document into an editor
that supports 'alt' codes. On Windows, I just tried Microsoft Word.
 Hold the alt key down and enter the 2-digit code (on the numeric keypad) for the symbol
you wish... ↑ is 24, and ← is 27. Just did a quick test and both printed fine on my HP
printer, although as I recall the resulting symbols didn't look quite like the arrows
in the original document.

 I remember having a 11/03 system at work back in 1984 that had an
 attached printer with what looked like an ordinary parallel printer
 connector.  However, the signal protocols for the printer interface were
 different than the standard parallel interface everyone was using on
 their PC's.  I think they were close but you needed a printer that
 understood the DEC protocols.  Shouldn't be surprising to anyone from
 that era.
