Sendalo is a web/mobile interface to an emscripten build of the excellent
|
||
<a href="https://github.com/datajerk/c2t">c2t</a> tool by
|
||
<a href="https://github.com/datajerk">datajerk</a>.
|
||
</p>
|
||
<p>
|
||
c2t is a really clever program that allows transferring disk images to
|
||
a running Apple II (among other things).
|
||
</p>
|
||
|
||
<h3>Why do I think this is useful?</h3>
|
||
<p><ul>
|
||
<li>The ASCII Express site is fun and a great idea, but it has
|
||
limited selection.</li>
|
||
|
||
<li>ADTPro is fantastic! But you need a running modern PC, and
|
||
some means of bidirectional communication to make it work.
|
||
Ethernet cards are expensive, serial not readily available
|
||
and audio mic input jacks are becoming difficult to find on
|
||
modern laptops. And there is no mobile version.</li>
|
||
|
||
<li>c2t will work with just a simplex link, so all you need is an
|
||
audio cable and there you go! But you still need another
|
||
computer and typing commands in the terminal.</li>
|
||
|
||
<li>Finally, with this frontend you can unleash the power of c2t
|
||
directly on your mobile device, with just an audio cable
|
||
and no PC. Just paste the .dsk image URL from your favorite
|
||
web archive, or upload your own, and the disk will be streamed
|
||
over. Also nice on computers if you don’t want to download
|
||
executables or type commands.</li>
|
||
</ul></p>
|
||
|
||
<p>
|
||
c2t can do a lot more than this, don’t forget to check the official
|
||
project page on GitHub to learn more.
