It is also on the 4010. The 4010 and the 4014 have a
card cage into
which you can insert your own cards.
I have a 4010 and didn't see any mention of this in the manual. Do you
know if it took special cards?
At the very least it would be interesting to
add a USB port to the Tektronix this way to give it a higher serial
transfer rate. The number and complexity of the dynamic vectors that
you can draw is currently limited by the baud rate on the port.
On the 4010 you can exceed the draw rate for stored vectors when running
at 9600 baud and you don't sent the unchanged bytes in the coordinates.
I was trying reduce the draw time to make a better demo and found that
long vectors wouldn't line up properly at 9600 when several of the bytes
didn't need to be sent.
