I recently got hold of the better part (if not all) of 75 or so volumes of CP/M files from "SIG/M, A USERS GROUP IN NEW JERSEY". Does anyone know if this has been archived somewhere already, or eventually have more info about this user-group?

Currently I am in the process of reading all of these disks at the moment, it's spread about in a collection of about 200 disks from various sources. Most of the UG files are on 8" double-density disks, so while there's 75 volumes, up to 4 volumes often share one disk (i.e. most of the disks in the collection is other stuff).
 
I had a look around, and I did find some of the same files of the disk I was looking at. However, it seems like the files I have are divided into other volume numbers than the one used there. For instance, the file I was looking at is in Vol 5 on that web archive, while it's in Vol 59 on the disks I have.
 
The SIGM archives used to be found here:

/cpmarchives/cpm/mirrors/oak.oakland.edu/pub/sigm​


I have a copy, here is an index of all 310 volumes:

I will go through and check when I have read everything..

There may be some differences, for instance it doesn't seem like the list you sent contain any commentary by someone calling themselves Zoso. A few of the disks I have has these.
 
Maybe what you have is 92 volumes of the CPMUG archive
I have a copy of these too

Attached is an index of these disks

A yes, that matches. It would also explain the discrepancy between these volume numbers and the SIG/M volume numbers.

After going through everything, I got vol 18 to 75 inclusive, except for vol 39 which seems to be missing from that box. I imagine there's two boxes with vol 1-17 and vol 76-92 that the owner of these disks either did not find or did not get.

I recall being sent a pile of the SIG/M disks for retrieval and telling the customer that they were already on the web. This was quite a few years ago; I'm a bit surprised that the question is still being asked. I think that the Walnut Creek CD collection even had them.
 
Those files were from a Tandberg CP/M Computer, which I had no cpmtools Definition.
This one worked.

Code: 
# cpmtools
# TAN1  Tandberg Computer  256 bytes/sector - DSHD 8" - 256 x 26
diskdef tan1
  seclen 256
  tracks 154
  sectrk 26
  blocksize 2048
  maxdir 256
  skew 1
  offset 13312
#  boottrk 4
  boottrk 0
  os 2.2
end

# libdsk
[tan1]
description = TAN1  Tandberg Computer  256 bytes/sector - DSHD 8" - 256 x 26
#sides = extsurface
sides = alt
cylinders = 154
heads = 2
secsize = 256
sectors = 26
secbase = 1
datarate = ED

# Flashfloppy/GOTEK
[tan1]
cyls = 154

secs = 26
interleave = 1

To be honest, I think web search-engines being smarter and smarter, to a point where actual relevant sites for ancient references such as SIG/M is being filtered out or miss-interpreted, has a lot to be blamed for here.
 
My bookmarks have these two links:
Found at the first above link is http://cpmarchives.classiccmp.org/cpm/Software/UserGroups/SIGM/_README.TXT which contains this:

This is *HUMONGOUS* CP/M's restored version of the SIG/M archives.

Founded in May 1975, the Amateur Computer Group of New Jersey (ACGNJ) is
dedicated to the amateur computer hobby. For many years its Special Interest
Group/Microprocessors (SIG/M) maintained a library of CP/M software
released on a series of disks.

The SIG/M software collection is still available today from several sources.
However, most of them are incomplete, and/or exhibit signs of accretion or
corruption (e.g., the Walnut Creek CD contains a SIG/M collection which
lacks several volumes, has additional files added to each volume, and whose
files no longer match the supplied CRC values).

This is the *HUMONGOUS* CP/M Archives' attempt to restore the SIG/M
collection to as nearly original condition as possible. In brief, the goal
is to precisely match the file lists and CRC values supplied in each
volume's -CATALOG listing.

This goal has, I believe, been almost entirely achieved, and is presented
here, in several formats: in expanded directories, and packaged as .ARK,
.LBR and IBM-3740 format .DSK images.

_SUPPORT

The _support subdirectory contains a number of files, most importantly
buildvol, the BASH shell script used to build this collection. You may use
this script to rebuild the collection yourself, if you're so inclined (read
the comments in that file for further information). But the most up-to-date
version can be obtained from Github at:

github.com

GitHub - CPMArchives/SIGM: Rebuild of the SIG/M Software archives for CP/M

Rebuild of the SIG/M Software archives for CP/M. Contribute to CPMArchives/SIGM development by creating an account on GitHub.
github.com github.com

If you wish to rebuild the entire collection in one fell swoop, copy
_support/ to a writeable directory, download the ISO files (see notes in
buildvol), then just run _support/buildall.

Also included is -CATALOG.ALL which is a rebuilt-from-scratch version of the
individual -CATALOG listings offering a complete list of SIG/M contents.

I would like to propose a better definition:

Code: 
# TANDSDD  Tandberg Data  256 bytes/sector - DSDD 8" - 256 x 26 MFM at 500Kbps
#
# NOTE: Track 0 Head 0 is SSSD 128 x 26 FM at 250Kbps, and the entire Track 0 remains unused
#       First half of Track 1 Head 0 is first system track data
#       First half of Track 1 Head 1 is second system track data
#
diskdef tandsdd
  seclen 256
  tracks 154
  sectrk 26
  blocksize 2048
  maxdir 256
  skew 1
  offset 9984
  boottrk 2
  os 2.2
end

This works with non-truncated images, and actually reflects where on the disk the boot tracks are located.
