I have some diskettes that have data and programs from an old HP150.
Is there anything other than an HP150 disk drive that can read the data from them?
I have a few computers ranging from Windows XP to whatever dos version from 1993 and neither of them will read the DISKS.Are the diskettes write protected?They appear not to be write-protected.Read this:

http://fixunix.com/hewlett-packard/102279-old-hp150-read-diskettes-problem.htmlThat's close but not quite the problem. My problem is that my PC, even in DOS mode doesn't recoginze the diskette at all. When I try the command "dir", it beeps and prints nonsensical characters.

I think the disks may have a FAT-12 file system or a FAT-16. Do I need a special driver to view the data on my Windows XP?This is the error message I get:

"The volume does not contain a recognized file system.
Please make sure that all required file system drivers are loaded and that the v
olume is not corrupted."It looks like DOS used on that computer was not real MS-DOS, and this may be your problem...

The HP-150, a "compact, powerful and innovative" computer made by Hewlett-Packard in 1983 and based on the Intel 8088, was one of the world's earliest commercialized touch screen computers. The machine was not IBM PC compatible, although it was MS-DOS compatible. Customized MS-DOS VERSIONS 2.01, 2.11 and 3.20 were available.
