Yes I was asking myself the same question, and your answers continue to help
a lot.
I think I should retrace the path of technology evolution. Start getting it
up with paper tape tests and BCS. That probably means working mostly in
assembly and getting to know the most basic level of the machine. Which is
just about what the doctor prescribed.
Then add the mag tape for which I have the tape and the cards.
I got a 7900 disk though (with cables and power supply, but no interface
cards to go with it!). I'd love to get that one going later on. Then it
would make sense to have the bigger memory to run disk based OS systems. So
7900 interface card and memory are definitely on my hunt list...
By the way I also have a punched card reader which I just restored.
Documation ML600, but the exact same model that HP re-branded I believe. Do
you know which interface cards I need to connect it to the HP-1000? I
suppose one of the 16 bit IO ones with a driver to go with it?
Sorry to keep picking your brain, but that is so much more efficient than
trying to piece it together (usually wrong at first) from an disorganized
pile of documentation!

I'd suggest that the question to answer first is
whether you want to expend
the effort and expense to gather the moderate amount of
additional hardware
necessary to run one of the more advanced disc-based OS
versions that can
use DMS. Note that the design of the memory mapping hardware in the 1000
requires explicit software support (i.e., programming of the DMS hardware)
in order to use more than 32KW of memory. Earlier OSes that did not
support DMS will simply ignore all memory in the machine over 32K, even
when DMS is present.
With the hardware you have, you can run a paper-tape based OS, such as BCS
(the Basic Control System) in 24K. BCS is fairly primitive, but it does
offer an assembler, FORTRAN IV, and ALGOL compilers, and paper-tape BASIC
interpreters were also available (from the user contributed library).
The hardware requirements for running the disc-based RTEs are listed on
these HP Computer Museum pages:

Assuming that you have a working paper tape punch and reader, and the
associated interface cards, then that's a very workable approach.
I got a 7900 disk though (with cables and power
supply, but no
interface cards to go with it!).
The interface is HP product number 13210A. It's a two-card set; the card
numbers are 13210-60004 and 13210-60000. The I/O cable is 13210-60003.
I'd love to get that one going later on. Then it
would make sense to
have the bigger memory to run disk based OS systems.
The 7900A was supported through the final RTE versions. However, you could
run the disc-based DOS-III OS with just the hardware and memory you have
(assuming that you add the 7900 disc I/O interface). With the addition of
a HP 12539 Time-Base Generator card and 8K more of memory, you could also
run RTE-II on a 7900. Neither DMS nor more extensive memory is required
for these OS versions, which are substantial steps up from BCS in terms of
sophistication and ease of use.
By the way I also have a punched card reader which I
just restored.

That's either the HP 2892A or 2893A, depending on whether it has a TTL or
differential interface, respectively.
Do you know which interface cards I need to connect it
to the HP-1000?
The interface is the HP 12924A, which was specific to the 2892A card
reader. The 2893A was supported only on the HP 3000, as far as I know.
I suppose one of the 16 bit IO ones with a driver to
go with it?
The general-purpose TTL interfaces apparently would not work. Drivers for
the card reader were supplied with the various OSes.
Sorry to keep picking your brain, but that is so much
more efficient
than trying to piece it together (usually wrong at first) from an
disorganized pile of documentation!
I'm glad that I can be of help.
