I think I saw a card read/punch only once on a PDP-6 IIRC,
but it
<br>
might have been a KA10. I don't think I ever saw one on a
PDP-8/11
<br>
or Vaxen.

The more I think about it, there must have been one or two in
the mill or the machine room in MRO, but I just can not picture
them.

As far as I know, there was no punch for the PDP-8 or PDP-11.
However, there were readers.
<br>
<br>
And the PDP-11 reader controller sat on the Unibus, so it would
not be hard to get it working on a VAX either. If that was
officially supported or not I don't know, though.
<br>
<br>
There were a bunch of PDP-11 Unibus peripherals that was never
supported on a VAX. DECtape comes to mind, as well as RK05.

<p>See my previous note.</p>
<p>The punches you mention do exist, as do others (Not particularly
common or popular):<br>
</p>
<ul>
<li>PDP-11: CP11-UP Punch interface for Univac 1710 Card RDR/PUNCH</li>
<li>PDP-8: CP08-(N,P) (CSS) Data Products Speedpunch 120 100 CPM
Punch and controller</li>
</ul>
<p>Card readers were sold and supported on all systems thru VAX.</p>
<p>Someone wrote a DECtape driver for VAX - I think Stan R., though
it wasn't supported. DECtape controllers are odd devices - the
TD10 is reasonably smart, but the others put realtime constraints
on the drivers that could be hard to meet. Anyhow, by the time
the VAX came out, TU58 and Floppies were cheaper and denser media.<br>
</p>
<p>There was also an unsupported DECtape driver for TOPS-20.</p>
