Re: HP 9144A Cassettes Types?

 

Martin,

 

Refurbishing the capstan isn’t difficult, I use neoprene rings made of ‘precision hose’ a hose type with the hole exactly centered.

And glue those to the capstan wheel, I’ve done several 914X drives this way it always work.

When you have the drive apart it’s also good habit to clean the head and lift mechanism and lubricate where necessary (use as little as possible only where needed!). When using the drive be patient the tape will be spooled all the way to the end before the drive is ready, the drive uses the end of the tape as block 0.

 

-Rik

PS. If you need a test tape I have some spares.

Onderwerp: [VintHPcom] HP 9144A Cassettes Types?

 

yesterday I obtained a HP 9000-320/Extender combo together with a 9144A cassette drive.

Now I would like to test/fix the tape drive and I understood that it takes preformatted cassettes:

Original HP Designations:

  • HP 88140 SC 16.7 MB per "S" cartridge 150 ft
  • HP 88140 LC 67.6 MB per "L" cartridge 600 ft.

These are difficult to find and I would like to know whether someone can confirm that these 3M types would also work (or which will surely not work):
3M Data Cartridges:

  • DC600HC
  • DC615HC
  • DC600XTD
  • DC615XTD

These seem to be preformatted in 3M HCD-75 or modified HCD-134 format which seems to be the proper format. Not sure...

Thank you,
Martin

"sloooow" and "tape drive" are synonymous. The whirring sound of an HP 9825A DC100 drive in rewind is burned into my brain.

Obviously these "HC" tapes seem to have the proper preformat.  I was not sure whether the "XTD" tapes would also work in the 9144 but the HP-Museum's text seems to indicate that these work only in the 9145 drive.
If I don't get any explicit confirmation I will try to get some "HC" tapes hoping that these will work.
As far as I understand the 9144A could work like any other SS/80 disk drive - only very sloooow  (yes, it is a backup medium).
The HP 9144A also seems to write some usage counts on the tape like on some flexible disk drives (the early 3.5" SONY drives 9121/9122 come to mind) to make the unit read-only to warn the user of potential data loss.
Thank you,
Martin

Re: HP 9144A Cassettes Types?

I'm not an expert, but the HP Computer Museum in Australia has this authoritative statement on the HP 9144A Web page, which also has detailed, experience-based instructions for refurbishing the drives' capstan if it's gone gooey (http://www.hpmuseum.net/display_item.php?hw=257):


"The 32-track tapes used in the 9145 cannot be used in the 9144. However, the 16-track tapes for the 9144 can be read by the 9145 (but not written to). These tape drives used pre-formatted tapes that are no longer being made. The Imation part number for old tapes that work is DC600/615HC (for the 9144A) and DC600XTD/615XTD (for the 9145A). Standard QIC tapes DO NOT work in the HP 9144 or 9145 (like the Imation DC600A)."

C1700C belts #VintageHPComputers

David Collins
 

I'm in the process of restoring an HP C1700C Model 20C Optical Disk library and need to get replacement toothed belts as they have perished and fallen apart. 

The HP Part numbers are C1700-60034 (includes 2 belts) and C1700-60035.  There's a few mentions on the web but I haven't found anyone that has them - no surprise.  

I know I can get belts from SDP-SI if I know the number of teeth/pitch/length of the belts.

Does anyone know of a source for belts or might know the specs of the belts used in the C1700C library? 

Thanks in advance
David Collins

Re: HPDir & HPDrive on Linux

Ansgar
 

Nice. Matches with my own experiences. Using a lightweight linux outperforms Windows ME.

Concerning systemd there has been lots of discussion around it, since it breaks with several traditional startup procedures. I am not in that deep, but things with Linux are changing, at least the larger distros have to deal with increasingly complex tasks, and there never had been a standard over the distros before systemd. So once you knew just on your own system how to install your startup configs, you have been lucky. If you were required to do the same for several distros, you had real fun. Some other things also have changed towards services rather than single files, like the system journal. For a lightweight linux, this might of course be overhead, but for the larger and more complex scenarios, this can help creating better architectures.

However, with all of its features, systemd sometimes reminds me of UEFI, where I suspect even a couple of mainboard manufacturers do not understand how it works (I don't either). A comparison which is not completely correct, because systemd is open source and the result of an open discussion, which is not true for UEFI.

Anyway, even with systemd it should not be too hard, as far as I know you have to write a minimum service description file with 6 lines or so, where the call of a startup script is configured rather than scripted. Supposed I like to run /usr/local/bin/myinit.sh during startup, I first create a custom service config file /usr/lib/systemd/system/my.service containing

[Unit]
Description=my service
 
[Service]
ExecStart=/usr/local/bin/myinit.sh
 
[Install]
WantedBy=default.target
 
I set access rights like

sudo chmod 664 /usr/lib/systemd/system/my.service
sudo chmod 744 /usr/local/bin/myinit.sh


The new service description now must be registered and enabled with systemctl, and this should more or less do it (didn't try on Arch, I have to confess :-)):

sudo systemctl daemon-reload
sudo systemctl enable my.service

Jack,

The only difference between a B and a T is the presence of the second RAM card with the mapping state machine, it is easy to tell the difference between the two cards, the card that makes it a T only has two large chips on it, while the B base RAM/ROM card has 11.  I saw a 9825 come up on eBay that is listed as a B but looking at the pictures it does in fact appear to be a T.

Paul.

Since they were kind enough to provide an email address, I've emailed them and asked if they'll tell me their story. If they do, I'll write it up and add it to hp9825.com.
