Well, not HP but a continuous memory with a 128 program fully merged. It's on the way in mint condition but

NO MANUAL.

I have searched and searched and cannot find an Internet copy. Does anyone have one or can any one spare their copy while I scan it for posterity and post the results.

It will save hacking my way through it, although that would be fun.

Nice to have a programmable with the blue florescent display ticking away as a program runs.

Geoff,

Nice find! I'm sorry that I can't help you out with a manual, but if you do find one can you please scan it for my website. I'm sure that there are other people that would like to have access to this.

Hi Katie!

Well our little on (Sealyham terrier) has had us on pins and needles for the last 8 weeks. Thank gosh for pet insurance, MRIs, CAT scans, spinal tap, ultrasound, adrenalectomy, anti seizure mess and now she appears back to normal :-)

----------------------------

I went directly to your site and found that it was missing :-(

So if I get one, plus there were some application books also, my plan is to scan them and post them and of course I will send them to you for your site.

At the moment, it looks in the archives like Hecube has one but his email link through the museum site is not listed, nor can I find any recent postings by him. Also someone who created the HPINSPACE web site has a manual but I cannot find an email address for him/her at the blog.

They are so out there but may be made out of unobtainium! Looking forward to hacking my way through it though!

Cheers, Geoff

I'm glad to hear that!

From this example and this example it looks like its programming model is pretty simple. Labels, unconditional branching, a few comparison tests, and at least one-level subroutine calls. I don't think it has indirect access to memories, but maybe, there seems to be an 's' register not used in these two examples.

It should be fun figuring it out!

Yes, found those two and they will be helpful. From previous posts at the museum there appears to be no indirect addressing.

What I like is the limited program steps. Makes you really think about efficient code. It would appear, for my 'suite of aviation related programs' that require 5 storage registers that the other 7 registers can be used for constants. That will make my following programs about the max that I can do:

Waypoint load
Great circle
Intermediate latitude
Altitude correction due to low temperatures
X-wind only
Fuel in tank check

These all fit my 34C with 165 lines of programming including the constants like .00198, 273, 360, 15 using up lines of code. By storing these, some of which are used more then once I should be able to squeeze it down to 128. Might have to drop the waypoint load and manually convert the DMS to decimal and store them.

Will be fun to take to work along with the 34c

That's what I like too about programming old calculators (up to and including the 32sii but excluding the 41c). The challenge of programming in limited space with limited instructions is really enjoyable. I like this too even on modern machines, but there the constraints shift from limited memory and instructions to limited time and/or other real-world constraints. Professionally I often have to program in archaic languages with limited capabilities, that too is fun!

Jeff,
I sold Mike Sebastian at calcinfo.com my 1201c with manual several years ago.
You might see if he still has it. It was a neat machine.

Thanks Bob!

I have been playing with the HealthKit, lots of fun!

HealthKit I've made that typo before too!

Is this one of their calculators that you're referring too? The OC-1401 Maybe?

HeathKit Navigation calculator and all accessories, nice! I have quite a few nav/aviation calcs.

Thanks IPad auto correct and confirmation bias!
