As far as I am aware, nobody has done this before

Here we have a music video featuring HP-41CV, HP-15C (LE, 1:0, 00927, obviously :), then TI-59, a bunch of Sharps, a bunch of Casios... Can you identify them all?

Go to Pandovisia/Songs and then look for "Girl From Facebook". The video is posted on a popular site - and here is a direct link for convenience Pandovisia - Girl From Facebook

Now, a challenge for the members of this forum: which calculator's display is at the bottom of the screen from about 3:05, and which function is it executing?

Also, a mini challenge for Sharp fans: which simple command causes Sharp pen plotter CE-150 to draw four squares on its own, one in each colour?

Enjoy

PS Best regards to Hrast Programmer! Maybe we can collaborate on a single one day :)

Probably a 65 or 67 running a user program. No way to tell what the program is, probably just an arbitrary loop for filming.

My guess:

Right after the 15C flashing "running" is a Spice machine (probably a 34c) running some program, possibly an integration or solver equation.


#13

Well done! Spice. It indeed is a 32E, running the rarely seen and implemented inverse normal distribution Q^-1 function, producing a "mysterious" display dance, just right for that scene. Maybe I'll post a picture of the whole calculator crew behind this video one day - I first have to think how to put them all in a single frame...

I'll take the easy one:

TEST

Easy :) I didn't have enough time to write a program to draw a flower or a star or something, so I "cheated" with TEST. How many viewers of that video will know what a pen plotter is, that's another question.

Very Clever!

Atari made a small 4 pen plotter for use with the 8bit (400/800) series. I wonder if the Sharp plotter is the same mechanism.

Some people still use pen plotters quite regularily.

I think a number of companies used the basic plotter mechanics, which I believe were made by Alps, and added their own controller/electronics. The Radio Shack CGP-115 and a Panasonic printer for their HHC's both used the Alps mechanism's.

The CGP-115's usually succumbed to "split drive gear syndrome" - the nylon drive gear on one of the motors (pen drive, I think) would split lengthwise and that was that. Great little gadget though, and extremely easy to control. Using a small program I found in BYTE as starting point, I wrote a translator that let it emulate a Tektronix graphics terminal, which was pretty handy in school.

Great and interesting video, with great collection of calculators! I really enjoyed it ...

I am always open to collaboration :-)

Keep up the good work!
