You're welcome. I wouldn't mind a copy of the files if anyone could get
me a copy. It would be nice to try this thing out.
I was able to make a working disk and just thought I would write a
summary to get all the details in one message.
1) Versions
The software version must match the ROM version. We have seen 1.00 and
2.00 ROMs. The ROM version is printed on the screen during the initial
self test. If the versions don't match you will get the message 'Disc
and ROM versions do not match'.
The same software seems to work on 1650A vs 1650B (Maybe that is what
determines the ROM version?)
2) Disks
You will have best luck with a Double Density (720kB) disk. If you
don't have any you can cover the hole on an HD disk (Opposite from the
write protect tab) with tape.
Format the disk under DOS or Windows and make sure there is no bad space.
3) LIFUTIL
The HP1650 uses LIF formatted disks. LIFUTIL program lets you read and
write LIF disks under DOS. It is an old program and hasn't been
supported for years. It will work best on older (Pentium) machines.
LIF was also used by some old HP computers and calculators. Most info
about it on the net refers to these systems.
Get it from
ftp://ftp.hpmuseum.org/lif/lifutil/
4) Files
The two important files a
SYSTEM_ - Operating System
and
PVTEST_ - Diagnostics (Needed to run self-test from the I/O menu)
The other files will be example configurations. The ones I have are
TIMEDEMO, STATEDEMO and MIXEDDEMO.
5) Making the Disk
If you can borrow a working disk your best bet is to make a copy on the
analyzer ([I/O] - Disc Operations, Select 'Duplicate Disc' as the
operation).
Otherwise put the files you want on the disk and LIFUTIL on a PC with
DOS or Windows (May need to be in DOS mode).
1. Run LIFUTIL
2. Choose 'LIF Initialize'
3. Change the settings to:
- Disk type: 3 /12" Double Sided
- Sector Size: 1024 bytes
- Interleave: 1
- Directory Size: 144 Files
- Volume Label: A165X
4. Press F5 twice to format the disk
5. When it is done press F8 until you see the menu
6. Choose 'DOS to LIF Copy'
7 Use these settings:
- DOS File Name: File you want to copy, start with SYSTEM_)
- File format conversion: Binary image: No format change, user-def. type
- All other can stay the same
8. With the cursor on the File format conversion line, press F6 to set
the file type.
For system files (SYSTEM_ and PVTEST_)
User-defined LIF file type : C001
Implementation specific field: 534F544F
For config files
User-defined LIF file type : C120
Implementation specific field: 534F544F
For other files (Reverse Assemblers, etc)
Unknown. If you have a disk list it with LIFUTIL. LIFUTIL shows the
type as a signed decimal number. Convert it to hex.
9. Press F5 to start the copy.
10. Repeat 7-9 for any other files you want to copy to the disk.
11. Boot the analyzer with the disk.
12. Make a copy of the disk on the analyzer. This copy may work better
than the one made on your PC due to differences in the drives. Make
another backup copy and put it in a safe place.
6) Error Messages
'ERROR READING SYSTEM FILE' - Wrong file or bad disk
'CANNOT FIND SYSTEM FILE' - Make sure the file SYSTEM_ is on the disk
and has a file type of C001
'ROM and Disc Versions do not match' - Make sure your software version
matches your ROM.
