HP41 Custom Module ???
Message #1 Posted by Randy Sloyer on 29 June 2003, 7:47 p.m.

I have an HP41 module that I would love to know what it is. It has no external markings of any kind, the label area on the bottom where the HP label normally resides is a bit smaller and is blank.
When the module is inserted in a CX, the contents will execute upon power up. I see one goose for about a second then the display shows WAIT.. After about 30 seconds to a minute the 41 beeps and shows READY in user mode.
Doing a CAT 2 shows NAVCOM 2. Anybody have any idea what this puppy is ?

Hi,
it seems to turn the HP-41 into a NAVigation COMputer;-)

Via HP-IL? Or ?
Who made it and what else does it need to function?

Hi,
sorry I don't have this module (so far), but I'm sure the 'hardcore module collectors' Matthias, Mike, or Peter Petersson do have it, and could give more info on it;-)
I think it's a stand-alone solution, which seems to be most practical when sea is rough (not many items which can fly through the cabin).

Hi Raymond,
You're right, hard core. Someone offered to buy but no information on what it is. I was hoping for a great story on it's history and use. Oh well.
Thank you for the effort, at least you tried.

I do not know who you ment with 'Mike', if it's me: I do not regard myself as a "hardcore module collector" as too many third-party modules (the rare birds) are still missing in my collection. What I did is a nice tool to analyse the contents of HP-41 modules, alas it runs only on VM/CMS (IBM mainframe). http://ourworld.compuserve.com/homepages/nutem/aro.htm
If you don't mind, you may send me a copy (hp41cx_at_web_dot_de) and I analyse it like all this: http://ourworld.compuserve.com/homepages/nutem/romim.htm
Ciao.....Mike

Ha! Là il est! Le vrai HMC! Salut Emmanuel! Ca va?
Well, yes most functions seem to be the same as in NAV1B, but there are few new ones. Is it possible that someone copied together what he found useful for his/her own purpouses. Or do you have a manual especially for the NAV2A in your hands?

If you don't have an IBM mainframe handy (:-)), then you might want to look at the 'rom41cat' program in my LIF Utilities for Linux distribution. It's written in C, and should be reasonably easy to port to other OSes. It doesn't do quite as much, but it will list the function names, whether they are Focal or Mcode, and the entry points. I find it quite a useful tool for looking at unknown ROM images.

Sorry Mike, I really don't know.
I tried this emulator a couple of years back for a short time and had a few problems with it (some errors in the source prevented compilation, but I finally managed to try it a little. At the time I was in a nostalgic mood for the days past... kinda like when I began collecting HPs. No, I won't begin looking for used IBM mainframes: already out of space! ;-)
I really hope that it can be of help to you.

This reminds me of the famous Chaostron April Fools paper which ended as follows:

Quote:
Our acknowledgments and thanks are due to Mr J.B.Puffadder for his assistance in the detailed design of Chaostron, and to Mr V.A.Vyssotsky for manually simulating the [IBM] 704, simulating STRETCH, simulating Chaostron, to complete run 133 after the budget funds ran out.
