DSI model NC-2400. https://vintagecomputer.net/temp/DSI2400_TapeReaderPunch/ I am going to try to bring this to the swap at System Source in November, but if anyone is interested before that contact me through vintagecomputer.net/contact.cfm to make an offer. I am thinking around $500 because it's tested and jumpered for rs232 2400 baud for easy use. Not perfect, but it does read and write tapes. A person has to keep a little tension on the tape as it pulls through the reader as it is now, but that may be because it needs to be re-greased. What's important is that it reads the tapes correctly. Comes with a new spool of tape, manual, gender changer, power cable, test tape. I have tested reading and copying a tape successfully with the unit. I am selling because I have a same-spare and I am clearing out duplicate hardware as time permits. Located in Landenberg, PA. I am willing to meet 1/2 way if it's not too far, or will consider shipping but I much prefer to sell either at an upcoming event or if you're ok with picking up in Landenberg, PA (near the University of Delaware). I accept cash, credit card, paypal, venmo, cashiers check. Hoping someone can use this. Bill
