Getting someone else involved is the next logical step. Waiting on approval from management to do so. Got to love corperations!! LOL
I will do my best to answer your questions...
Looks as though it is running SCO Xenix System V Version 2.3.4, 386 OS
As for the hardware, this is running in a Compaq ProLinea 4/33 with a whopping (single) 120 MB Quantam HDD and 8 MB RAM. The only other real hardware this has is a multiport Arnet adapter card connecting to an RS-232 Arnet board for the modems and the printer. Not sure what else I can tell you about the hardware.
You commented that you didn't know anyone still used file system based pipes. This system is at least ten years old, should have been put out to pasture nine years ago in my opinion. For whatever reason, no one ever felt the need to upgrade for whatever reason. Currently we are working on locating spare equipment to hopefully be able to replace this unit. From what I have read in the software documentation, all I have available software wise, is an upgrade. I have not been able to locate the original software package.
I have been able to successfully navigate through the file and directory structures. So far, the only problems I have found is in trying to set up a different user, it comes up with errors trying to open or modify different files.
The system will boot as far as the login prompt. Once the user and password is entered it goes nuts with the previsouly mentioned errors. That made me think it would be worth a shot to create another user and try to log in that way and maybe get around the bad section of the HDD.
Not sure what else I can tell you that may be of use. I do appreciate your time and input on this. Although, I don't expect any miracles, just thought someone out there can save me some aggrevation on this.

E2UNDO(8) System Manager's Manual E2UNDO(8)
NAME
e2undo - Replay an undo log for an ext2/ext3/ext4 filesystem
SYNOPSIS
e2undo [ -f ] [ -h ] [ -n ] [ -o offset ] [ -v ] [ -z undo_file ] undo_log device
DESCRIPTION
e2undo will replay the undo log undo_log for an ext2/ext3/ext4 filesystem found on device. This can be used to undo a failed operation by
an e2fsprogs program.
OPTIONS
-f Normally, e2undo will check the filesystem superblock to make sure the undo log matches with the filesystem on the device. If they
do not match, e2undo will refuse to apply the undo log as a safety mechanism. The -f option disables this safety mechanism.
-h Display a usage message.
-n Dry-run; do not actually write blocks back to the filesystem.
-o offset
Specify the filesystem's offset (in bytes) from the beginning of the device or file.
-v Report which block we're currently replaying.
-z undo_file
Before overwriting a file system block, write the old contents of the block to an undo file. This undo file can be used with
e2undo(8) to restore the old contents of the file system should something go wrong. If the empty string is passed as the undo_file
argument, the undo file will be written to a file named e2undo-device.e2undo in the directory specified via the E2FSPROGS_UNDO_DIR
environment variable.
WARNING: The undo file cannot be used to recover from a power or system crash.

e2undo was written by Aneesh Kumar K.V. (aneesh.kumar@linux.vnet.ibm.com)
