Paper Tape

I saw this on e-bay:

http://cgi.ebay.com/Paper-Tape-Reader-f ... dZViewItem

It looks like a cool idea. I always liked paper tape, an would think such an interface would be a lot of fun for the Replica or the Kim.

Does anyone know how to actually punch tape without an old reader/punch? I no longer have an ASR-33. :D

Quite expensive. Have a look at http://www.swtpc.com/mholley/OAE80_Reader/OAE_80A_Manual.pdf so you can build one yourself.

That's great! I may give it a try.

Using paper tape would be absolutely awesome in my opinion, particularly in a "modern" product, but I imagine the costs involved would be prohibitive for simply messing around, sadly...

I'd love to get into that and a switch-based (a la Altair/IMSAI) system, but they're never within a reasonable range...

I've personally never used paper tape but I've seen them once or twice. Simple technology but finding the mechanical parts or making them is another story. The one on ebay is way overpriced in my opinion.

Here's the problem, the dumb switches of any quality are $2-$5 each! Now, take the Altair and multiply that by 24..ish and it really adds up. Still, I think I need to revisit a front panel for the replica 1. I think I might be able to make something that works with both the replica 1 and Micro-KIM. After the VCF midwest this weekend I'll look at it. I have a "few" other things in the mix :roll: that I'll hopefully be announcing.

A front panel for the Replica or the Kim would be great. I used one back in middle school (along with paper tape) on a PDP-8 clone.

Its time consuming, but there is something fun about toggling in a program and stepping through the program to debug.

If you could somehow make a front panel that would work on both kits, that would be simply amazing. I know it's crazy, but I always wanted a computer with the switches just to try and program in that many. Short of punch cards and paper tape, that has to be the most hardcore way to program a system. Again, it's always been the cost that has kept me away, but if anyone can figure a way, it's probably you.

Ok, I'll look into it next month.

Maybe an optical paper tape reader would be easiest to make...
you could make one that doesn't need to be punched that way, so you could maybe modify a little adding machine to print it for you.
Might be a way to go about it.
