yes it appeared to be more complicated. The HDD is scsi.
I found Adaptec scsi adapter, connected my traget HDD and booted another machine with puppy linux CD. The HDD was found at boot and there what I could see with dmesg :

# dmesg
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0
<Adaptec 2940 SCSI adapter>
aic7870: Single Channel A, SCSI Id=7, 16/253 SCBs

SCSI device sda: write cache: disabled, read cache: enabled, doesn't support DPO or FUA
sda: unknown partition table
sd 0:0:0:0: Attached scsi disk sda

The disk was not listed on desktop for ones available to mount. I guess prelast message "sda: unknown partition table" was the reason. This was on my new linux box.

On the native machine during boot message pops up:

UHC UNIX System V Rel. 4.0 Version 3.6

then many messages about loaded modules

The uname -a returns:
fib1 4.0 3.6 i386 386/AT (fib1 - is user )

/etc/copyright - does not exist

With this original box flopies are formated at 1.44M and also I managed to make tar backups of some data. But my puppy linux could not mount them either.

Any ideas how to move on?

NAME
acorn-fdisk -- partition editor for Acorn/RISC OS machines SYNOPSIS
acorn-fdisk -h | --help | -v | --version acorn-fdisk [-t scheme | --type scheme] -l | --list [device ...] acorn-fdisk [-t scheme | --type scheme] -s | --size partition acorn-fdisk [-t scheme | --type scheme] [device] DESCRIPTION
The acorn-fdisk utility allows one to display or interactively edit partition tables for Acorn/RISC OS machines in various formats. Using the PC/BIOS format, standard IBM PC (i386) partition tables can also be accessed. When no optional device is given, it defaults to /dev/hda or /dev/sda. The options are as follows: -h | --help Display a short usage and exit immediately. -l | --list Display the partition table(s) of all devices. -s | --size Display the size of partition. -t | --type Select the partitioning scheme to use. Valid schemes are: EESOX Eesox SCSI on the Acorn machines. ICSIDEFS ICS IDE. Filecore/Linux Linux on Filecore. This uses the non-ADFS descriptor to point to the start of the disc to be partitioned. The first two sectors contain a partition table to identify the Linux partitions contained within. PC/BIOS PC/BIOS partitioning scheme. This consists of a partition table in the first sector of the disk which contains both CHS and LBA values for the partitions. There can be up to four entries in the primary partition table. One of these can be an extended partition containing up to four extra partitions. PowerTec PowerTec SCSI on the Acorn machines. Filecore/RISCiX RiscIX on Filecore. -v | --version Display the version of acorn-fdisk and exit immediately. If neither -l | --list or -s | --size are given, the partition table of the given device will be edited interactively. EXAMPLES
Display the default device's partition table on a PC: acorn-fdisk --type PC/BIOS -l Display the PC partition table of /dev/sda: acorn-fdisk --type PC/BIOS --list /dev/sda Display the size in blocks of the partition /dev/sda1: acorn-fdisk --type PC/BIOS --size /dev/sda1 Edit the MBR partition table interactively: acorn-fdisk --type PC/BIOS Display the partition table of an MBR backed up to a file: acorn-fdisk -t PC/BIOS -l mbrdump.bin Display the size of the first partition on a device where the MBR would be restored from the backup file mbrdump.bin: acorn-fdisk -t PC/BIOS -s mbrdump.bin1 AUTHORS
