I’m posting this in the hopes someone might find it useful for anyone who googles looking at how to deal with TELEDISK TDO format archives.

The HP site is really a terrific resource. Those TDO archives are pesky though. I was searching for the HPIB.SYS MS/DOS driver for the HP 82355A ISA card.

Here is the link: [ http://www.hpmuseum.net/display_item.php?hw=879| http://www.hpmuseum.net/display_item.php?hw=879]

and under software: [ http://www.hpmuseum.net/display_item.php?sw=57| http://www.hpmuseum.net/display_item.php?sw=57]

which leads us to HPIBTOOL.TDO

Here is how to use it:I created a very small VirtualBox client that I name “DOS” with 1 CPU held to 10%, 4mb RAM, 10Mb disk of type “Windows 98”. All acceleration turned off.I then installed DOS 6.22 by mounting the *.img files as floppies (it comes as a 3 floppy set).I then created another floppy using the command:$ dd if=/dev/zero of=myfloppy.img bs=1024 count=1440

Mounted this in the DOS client and formatted it:


I then mounted the floppy on my Mac and copies both the HPIBTOOL.TDO file as well as the Teledisk software TELEDISK.EXE obtained from:


mounted this “floppy” in DOS, and then ran TELEDISK.EXE to extract the TDO file into a second floppy, created the same way as the first. This creates an installation floppy for the HPIB driver.

Now only if there were a virtualization tool that allowed us to attach one of the USB<->GPIB converters *as if* they were an 82355A … oh well

In any case this is a general way to extract a TDO archive to a “floppy” .img in the comfort of your laptop while sipping espresso.
