I remember running on a 2000 Access system at the junior college I went to
in the mid- to late-70s. We had the option of running assembler on that
box, but it took too long to go back and forth between that and BASIC. So,
we did the next most logical thing: we ran an assembler interpreter under
BASIC. Talk about slow...
We also had a 2114 in that lab. I started using that my senior year in high
school. Paper tape and mark sense cards for input, teletype and paper punch
for output. Very advanced for the day. :-)

John,
The website at http://oscar.taurus.com/~jeff/2100/ does show the HP2100
series as growing into the HP1000 M, E, and F series.
The pictures on that site look like something between what I called an
HP2100, and an E or F-series box. The box I remember as a "2100" had lighted
pushbuttons on the front for manual entry into the A, B, P, and (IIRC) "T"
registers bit-by-bit, and also had a paper tape reader on the front. It
looked more like the picture of a 2100A at the taurus.com site, than like
the picture of a 2114A.
Documented at the taurus.com site is a configuration called TSB or HP2000A.
The site further states that the HP2000A was a timesharing systemand not an
actual computer. TSB means "Time Sharing Basic."
I do not see any references to the hardware being an ancestor of the HP3000,
nor am I aware of any architectural similarities (or lack of similarities)
between early HP3000 and the HP2100 line.
The 2100 series and the HP1000 line have always been 16-bit machines. RTE-A
did a very good job of overcoming addressing limitations of 16-bit
architecture.
RTE has a rich history, and not all of it was written by HP (IIRCA). I
believe the original file system FMGR was writen "outside".
My experience with the HP2100 familiy is this:
To learn a machine language and then an assembler,
1) write a program in machine code to make the register lights change in an
interesting pattern; load it a word at a time through the front panel
register push buttons, and run it.
2) Write a program in machine code so that when you strike any key on the
teletype (which is really two separate devices), the corresponding hammer
strike or carriage control occurs.
3) Same as (2), but bufferred until carriage return key is struck.
4) Write more sophisticated programs in assembler on an HP1000 running RTE-6
(or earlier), cross-assemble that to HP2100 machine code, punch it to tape,
load the tape to the HP2100, and run it.
Somewhere, I think I might even have all my homework and lab assignments
from that class!

Dave:
I worked on an HP2116B in '72 - '73, timesharing box.
Great piece of gear. Are you telling me that this wasn't the predecessor on
the 3000 but of the 1000?

Dear List,
I've seen references to the HP2000 a few times on this list.
I'm familiar with the HP2100 ancestor of the HP1000 (reference other thread,
RTE originally had no file system),
Of course I am familiar with the HP3000, and also HP9807, HP85, HP87, and a
whole bevy of disparate workstations and instrument controllers tagged
"HP9000", but,
What's an HP2000? Where can I get more info on it. How about online docs?
Thanks,
Dave
