Website Update
Message #1 Posted by Gerson W. Barbosa on 8 Feb 2006, 8:30 a.m.

Hi everybody,

My incipient website with a few calculators and a few simple programs has been updated and has moved to:

http://www.geocities.com/gwbarbosa/

Everyone is welcome!

Regards,

Gerson.

Hi, Gerson:

Nice site, but if I may suggest something, if I were on your shoes I wouldn't include the whole serial number for each of your calculators.

Something like "2142A01xxx" would be preferable. The idea is to give useful information (which the "2142A" already conveys) but *not* the whole number, just in case some cretin would claim that it was his "stolen" calculator or so. For items obtained via eBay or some other non-easily traceable source, that might be difficult to disprove, and considering the price these models gather today and /or the fact that they are sought for very keenly, this might be a not-so-unlikely scenario.

Not to be paranoid, but nowadays you never know and, as the old proverb says, "better safe than sorry".

Best regards from V.

Hello Valentin,

Thanks for the very good advice. Three or four of my calculators I have bought brand new myself, others were bought from allegedly first owners, but I am not sure about two or three. I had already wondered about that and you have made up my mind. Thanks again!

Best regards,

Gerson.

Update:

Done that!

There will be another change as I intend to sell the third 15C, the one with the logo almost worn out (I still need to buy some HP-41 accessories). But I will do this when I get another Voyager (a 12C or 16C) because I have now exactly 14 calculators. If I sold one I would have exactly 13 left! Yo no creo en brujas, pero que las hay, las hay. :-)

    You're welcome. By the way, your site seems to be a great success, as it's now impossible to enter because the allotted bandwidth has been exceeded ...
"I still need to buy some HP-41 accessories"
    May I suggest you get:

    1. A 41CX or 41CV + Time + Extended Functions + Extended Memory
    2. Card reader
    3. Advantage ROM
    4. PPC ROM
    5. book: "Solution Book: Games II"
    6. book: "Extend your HP-41C"
    7. book: "Synthetic Programming for the HP-41C"
    8. book: "Tips and Tricks"
    9. CD-R: PPC, CHHU, PPC Technical Notes, Keynotes

    plus manuals, mag cards, holders, etc, and you're all set up except for very, very special needs (mcode, etc).

"Yo no creo en brujas, pero que las hay, las hay. :-)"
    Excellent spanish ! :-) Wish my portuguese were as good ... The original galician (galego) proverb reads: 
          "Eu non creo nas meigas pero haberlas hailas"
    and usually translates to spanish as you quoted. For the benefit of English-speaking readers, this essentially means: 
           "I don't believe in witches but exist they do"
Best regards from V.

Hello again Valentin,

Thanks, but I don't believe so. The transfer limit is 5MB/h, that's about the total size of the fourteen 800x600 pictures. Anyway, the alternative site should be working.

About your suggestions, I have already number 1, a 41CX (you cannot tell by the pictures, I think, but the caption says so) and number 3, incidentally because of your suggetion in your Long Live the Advantage ROM article. Number 2 may arrive in a week or so. For the while, I think number 8 and 9 will do.

Well, I must confess my Spanish is not as good as you may have imagined... It just happens that this proverb is well know here and it is usually quoted in Spanish. I didn't know this was originally a galician proverb. As you know, Spanish and Portuguese look so alike (I don't know of two other major languages so mutually understandable) I never took the time to study it seriously, although I recognize I should.

Best regards,

Gerson.

My list of 'desirable' HP41 accessories is rather different :

  1. HP41CX or extended functions module (I don't find more extended memory or time functions to be essential)
  2. Card Reader (if only for the HP67 compatability functions)
  3. HPIL module (HP82160)
  4. Disk drive (HP9114A or B). IMHO the only reasons to have a tape drive is either because you want to collect all the HPIL peripherals or because you need to be able to read old tapes.
  5. Extended I/O module
  6. HPIL Devlopment module (DevIL ROM). The HPIL module is missing a lot of important functions, you need one or other of these 2 ROMs. Unfortunately, the DevIL ROM has the same XROM numbers as the Advantage ROM, so the latter is of little use to me.
  7. RS232 interface (HP82164)
  8. MLDL RAM box + some ROM to let you load ROM images from disk. With that you don't need a lot of the ROM modules. No, it's not so convenient, but it's probably cheaper and Mcode is interesting anyway
  9. ZenROM (if you can find one).
  10. MoHPC CD-ROM set
  11. Book : Extend your HP41. The best user-level/synthetic reference I've seen
  12. Book : PPC ROM manual. You can learn a lot from reading that.
  13. Book : HP41 M-code for beginners. I dislike the title, it goes way beyond that level.

If you're a hardware hacker like me, you probably also want to add :

  1. Service manuals or schematics for the HP41 and the HPIL peripherals
  2. GPIO interface (HP82165 or HP82166)
  3. Data acquisition unit (HP3421)
  4. HPIB interface (HP82169)
  5. Book : Control the world with HPIL

I actually have the Extend your HP 41 book. If you are interested in it, let me know.

Also, the entire PPC manual was just offered on ebay last week for $50.00 and no one bought it. Here is the auction info: Item number: 5861651593 - closed.

Joe

That PPC ROM manual has been relisted on ebay. Item number 5865423154

In the U.S., one is innocent until proven guilty. Someone can "claim" the serial number, but it would be left up to the plaintiff to prove it in a court of law.

But in other countries, perhaps it is different.

Nobody goes to court for a $300 calculator.

Just another perspective.
