Vintage Computer: Punched Paper Tape Reader

I remember many companies was applying for "punch" ladies to come and get a job. The job was to sit and 'punch' holes in such strips, or in paper cards.

I remember one of the population countings back in the 60's was done with the help of cards in wich we should punch holes in the right positions.

Very interesting, I would love to have this profound knowledge. I'm new to this Electronics, Arithmetics and Logic stuff and i find it is people like you who teach the correct and dont over confuse people with misleading answers.

Make more vids! :)

Where is the schematic for this?

Please provide some info on the project as well as how did you punched the tape?

[zeke1312]

Hmmm, I can remember working on both paper tape punch and readers. FYI, the small hole present even on a blank tape is where the sprocket drive pulled the tape through the reader/punch.

Brings back memories - never worked with paper tape but in my high-school computer science class, we entered in BASIC programs using cards.

[chickyoungsabawbag]

Like that

[richardblottable]

i dont know why, but i really want one of these!

[er10b]

what made me smile was that the University in Queensland would use their GE 225 to transfer programs from punched cards to paper tape, for what reason I don't know.

i have some perforated paper used by my father on a PDP8. maybe there is some software on them. do you want to read it...?

[isaacthewarrior2]

how do you make this?

[powerfist]

A light source would strike a light sensitive diode or such.

Each hole would let the light shine through.

No hole, no light.

[migrations]

Awesome



[Ms4dmin]

Have you done experiments to see how fast you can pull the tape through?

[lordpolvo]

what does it do ? looks pointless

[masterxilo]

@lordpolvo It reads data from a Punched Paper Tape?!? This was kind of the first cheap ROM (much like optical discs today) - much cheaper than some switches.

[lordpolvo]

@masterxilo Thanks :) using the optical disc comparison was helpful :) makes more sense now

[TheEPROM9]

@lordpolvo Look into the history of computers and then you shall be enlightened.

My friend and I wanted to revive the aforementioned retro-tech. Looks like we've been beaten to it, although my friend would like to know A LOT about how you made this. I'll tell him about this.

FANUC CNC's and FANUC Robots had controllers with punched tape reels.

[snarfusmaximus]

How and where can I get one of these?

[senorverde09]

This sir, is awesome.

[mrmikerotch]

Where do you get the tape?

[michaelboett173]

cool. :) build ur own tape-drive for an c64 like datasette or something. may be works on userport if u fix the LEDs to a speaker and using one of these first modems...don't know how they are called.... need a real phone and then beeeeb :) cool. :)

[GalaticTG]

Wait does the strip contain the code to initialize the LCD as well as put data on it.

That is a very impressive design.

[jklash2007]

Still use these at work to save programs from our CNC's

[adrifromhh]

@jklash2007

what the fuck? ^^

[brickman409]

@jklash2007

wow and i thought my schools computer lab with apple II's sucked

[smartpartzzkidd]

the hobos EEPROM / data storage system

[KanadaKid1215]

Wow. Was this a kit or did you build it yourself? Seems a lot simpler than others I have seen.

[jtel]

COOL.

[kravorzlair]

How many bytes of data could you fit in one ribbon ?

[iraeus]

That's cool :-)

I once thought of building a similar pocket reader. Do you have a processor on your board?

With a serial interface this would really rock!
