HP 150 A/B Touchscreen Disks?
I am quite sure that a few of you also have a HP 150 at home.

Recently I performed some maintenance on HP 9133 hard disk units and for this I used a HP 150 and a more recent HP 150 II.
I used disk images created from the TD0 files provided by the HP-Museum in Australia.
These comprise an early revision "A" of the operating system with MS-DOS 2.01 and a revision "E" with MS-DOS 3.2.
While the latter is more useful, it would be interesting to also locate copies of other revisions "B", "C", and, "D". Starting with "B" the MS-DOS Version should be 2.11.

If you still have original system diskettes for your HP 150, could you have a look and see, whether these carry a revision number other than "A.nn.nn" or "E.nn.nn" on their label?
If so, could you make copies with Teledisk or a similar tool?

(The HP-150 system came with 3 disks: "SYSTEM", "APPLICATIONS" "UTILITIES")

Thanks for looking,

PS: The HP calculator program also available in form of a TD0 image file should contain emulation of the 11C, 12C, 15C and, 16C, but the image file available on the web site only has the 12C emulation. So if you happen to have a disk with this software...
