Name that calculator



#2

Hi,

I've been lurking here for quite a while. But now I have an interesting question for you all.

When I was a kid, an acquaintance of my dad's stayed at our house for a few days. He was an engineer and had an HP calculator, the first electronic calculator I had ever seen. He let us play Lunar Lander on it quite a bit. It was vertically oriented with a red LCD display, and had plugin modules (I think). This was somewhere around 1977. I've been wondering what model it was likely to have been. Any ideas?

Well, I think you have to make a decision here:

  • If it was red, it had no plugin modules, but maybe magnetic cards, and you saw an HP-67 (alternatively, an HP-55, 65, 25 or 29 would also be possible).
  • If it was LCD and had plugin modules, it was 1979, and you saw an HP-41C.

Cheers, Victor

perhaps it was a ti and not an hp at all! eg sr-52, ti-58?


#5

My guess that it was a 25 or 25C. I don't know if HP wrote the Lunar Lander program for calculators other than the 25. Anyone knows?


#6

I recall there being a Lunar Lander program for the 33C, but that might not have come from HP.

#7

The HP-67 Standard Pac has a program called "Moon Rocket Lander".

Thanks everybody. After reviewing the pictures, I think the 67 best fits my memory.

So how much do they go for these days?

Take a look here:

I think that this one is somewhat expensive (mint NIB)...

Okay, here's a variation of the question posed by Glen:

Which was the first HP calculator (any kind at all) to have a Star Trek game? As an aside, how truly playable was it?

I have a copy of a Star Trek game written for the HP-25. This program was written by a fellow fan club member around 1975-76. He made a copy available to all the members at the time. Some 10 years later I used the basis of the program to write and modify it for the 41CX. There were 2 versions of the original program, one a 1 player game and the other a 2 player game. When I adapted it and modified it for the 41CX, I combined the 2 games into 1.

The basic premise of the game was, you and your opponent entered your 2 dimensional XY co-ordinate location into memory registers from a 100x100 grid. Then you would enter your guesses on the stack and fire. The closer you were to hitting your opponent the closer the number in the display would be to Zero. When the number in the display equaled Zero you won. 1701 would flash if the Enterprise won and Error would flash if the Enterprise lost.

My changes combined the 1 & 2 player games into one program and I added an optional 3 dimensional XYZ grid, with randomly selected Enterprises A, B, C, D, E, Defiant & Voyager. I also had a randomly selected opponent list; Klingons, Romulans, Gorn, Q, etc.

I had fun writing my version and playing both. I still have fun with it from time to time on the 41CX and the 42S.

Richard:

Mmm... My own candidate would be an HP-65 program from the Users' Library that was written on 8 cards; you switched from one card to another depending on what you wanted to do. To me, this program (wish I knew who wrote it) remains the highest representation of Homo Programmus' ingenuity facing the incredible restrictions imposed by the HP-65 architecture.

I was hoping to find an even earlier program. Someone once told me there was one for the 9100A, but I seriously doubt that.

Comments, anyone?

star trek on the hp-25!

#14

Hey! It sounds great; I wonder if I could ask you to port it to either or both of the 48 or 49 series RPL models!


#15

I will eventually get around to updating the game for other HP calculator, but the version for the 42S is the latest revision. This is the 42S version.

I have the HP33E and in the Application pac" it describes a game called "Moon Landing Simulator"
I think this answers your qn, yes?

Such "simulators" were popular at the time, and the manuals of the HP 67, HP 25, HP 29 and others include versions with minor variations...
