I got two kxtd1232's for use at work. We are a WW2 battleship memorial and we will use them to reactivate the old analog phones onboard. They are supposed to be ROM zeros and I have the 192 kit but they don't seem to be talking. The first one is Sn: 5ICIG009054 and the chips under the cover say P101A (IC20) and P102A (IC21), the other is:
4D IC001650 with chips P011Q (IC20) and P012Q (IC21). Thanks for any help you can spare. Terry
