Sort of. You will need to put an inverter in the timing track path (I
put it in the cable). Discussion from when I originally worked on this.

I was able to read some tapes but on the todo list is to build a better
reader since many of the tapes had too many errors.

I can dig up the code I wrote if your interested but it will need some work 
since it depended on the special interface board I made for the pdp-8 I have
online. Much of the work I did on the PC.

I can also give you the code the web site uses to display the tape contents.
