Yes, It is The Dealer Tape. Label say
Zebra/Pick Operatiing System, Revison 3.3b, 750/1350/1750/3760
Version 53a00124a01-a, Dealer Sysgen Tape Qic 24 Format

The problem I have with booting is that it has Disk errors
and I would guess it is no stable enough to make a bootable
tape if that is even possible.
Do you have any of the manuals on these or OS on how to
Make a tape ?? I would like to try and see if this tape
will even work. I was able to "DD" it with out errors

Another long-distance e-troubleshooting quandary:
Machine: SGI Personal IRIS 4D/20 (WDC 33C93A SCSI, single channel)
All disks pop up as unknown type, for instance the main system disk
comes up under the PROM as
Unknown SCSI type 191 / removable: scsi (0,1)
drive settings:
-ID: 1
-Time monitoring is disabled
-Read-Ahead caching is enabled
-Normal operational mode
-LED active when drive connected to bus
-CHECK CONDITION posted (unit attention response)
-Unlimited 250ms, 128 retries (scsi time monitoring)
-SCSI-2(scsi level)
-SAVE DATA POINTER is issued for disconnection (message mode)
-CHECK CONDITION status not posted(error report at mode select
parameter rounding)
-0 (PER default value)
-Motor start on power up (motor start timing)
-Executed by IDD (scsi bus parity check)
-CHECK CONDITION status not posted (synchronous mode transfer rate)
-Disabled (OPEN 1.2 to 2.67MB/s)
-Power is supplied to the terminating resistor from the IDD and TERMPWR
pin. Power is also supplied to the TERMPWR pin from the IDD. (Pin 26 of
the interface) (scsi terminating power)
new SCSI cable tried, terminator known working, drive visible from a
different machine (Linux PC). The devices pop up at the proper SCSI
IDs, but all are misidentified as Type 191 (I suppose this is a decimal
representation of the hex SCSI identifier numbers.) Is this likely a
dead 33C93A or is there somewhere else to look?
P.S. - we love you, Tony- Don't leave.

That was only the subroutine for dealing with disc reading. It's part of
a larger kludge I use for tape and disc reading.
The point was just to show what low-level scsi commands you need to send to
dump a disc.
Would make more sense to translate that to something that would work with the
generic SCSI driver under Linux.
IIRC the sound paraphenalia was the same or similar to
that used in the TI home computer.

Retrospect 2 ran fine on my Mac IIci back in the day. Ah, here are
the "Minimum Requirements" off of the side panel on the box:
Macintosh Plus, Hard Disk
System 6.0.5 (2 MB RAM) or
System 7 (4 MB RAM)
So a PowerBook 145 should work fine. A PowerBook 100 should also work okay....
You might run into problems with a much later machine or OS and
Retrospect 2, although as someone mentioned, later versions of
Retrospect will probably read your older tapes just fine. I have a
vague memory that when I went to OS 8+ and started using a PCI based
Mac I had to upgrade my version of Retrospect, but I'm not certain
any more whether that upgrade was necessary or just something I
wanted to do--or maybe to get later tape drive support.
Anyway, this came up in my emailed saved search for Retrospect on
Ebay today
<http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=230081470236&ssPageName=…>
which is a sealed version of Retrospect 2.0 with a $5 BIN and $5
shipping.
Again, as someone else mentioned, the tough part is going to be
coming up with a compatible (with your tape) working tape drive.
Also, once you have everything hooked up you'll need to run the
"Repair or Recreate a Storage Set" under the Tools menu. Under
Retrospect 2 that's a "Tools" sidebar icon and the selection is
"Repair/Recreate Catalog".
Presumably you no longer have the "Storage Set" file that Retrospect
created when it made the tape. So the first thing it will need to do
is to scan through the tape and recreate the storage set files for
that tape, I think. After that you'll be able to recover the
contents.
This always seemed like the most clunky aspect of Retrospect to me.
Presumably, if you've had a complete hard drive failure, the catalog
will be gone (absent multiple hard drives or server backup), so why
doesn't it store the catalog file at the end of the tape where it
could scan to the end and pick it up there instead of recreating the
thing from all the contents of the tape? Perhaps tape can't work
that way?
Ah well, anyway, there's a copy of R. 2.0 available and it should
work on any ancient Mac. They all had SCSI ports (except the very
early 128K and 512K and KE but they don't have 2 MB RAM anyway) You
just need to find a tape drive.
Oh, and OS 6.08 and 6.05 are free downloads from Apple, as well as
the version of 7 mentioned earlier, and any of those will work with
R. 2.0. So really, you just need a Mac old enough to run early
OSs, or find one with a later OS already on board or with OS media.

there was at least one Brazilian made unit, with a
detachable keyboard. Ive heard a rumor to the effect
that they were somewhat common in Mexico. Anyone?

Hi
I was surfing on the internet and saw your interest in kaypro co-power 88.
I have a kaypro 10 and the co-power processorboard.
My problem is that I only have a loader for the 256 kb Ramdisk but not the loader for running Msdos2.11
Are you willing to mail me a copy of the software .
Thanks.
Jos
I've had a couple of WTF moments from SS20s. Best one was when I got a
retired SS20 that I cracked open to find one SM71 MBus CPU and one Dual Ross
100 MBus CPU. It had been in reliable production, as a 3 proc box, for a
couple of years with one 70MHz, 1MB cache CPU and 2 100MHz, 256KB cache
CPUs. Solaris reports that it's using all 3. That's some robust
architecture.
