Hi Arno, I've got some X.25 equipment which needs a good home. I have two Satelcom switches, two Dec DEMSB routers and two 4-wire NTUs ("baseband modems?") plus a few cables and manuals. The switches power up and can be configured from a console terminal but have problems retaining their configuration over a power off. This is probably due to a problem with the internal PCB mounted batteries which I have had to replace previously. One of them has a push-on connector from the power supply replaced by a soldered connection where the connector had overheated. The NTUs also power up and appear to work. I haven't tried the DEMSBs. Normally the NTUs are clocked from the telephone exchange end but it is possible to change the links in one to get it to generate a clock internally so that the two can talk to each other over a 4 wire crossover cable. At least, I can get all the LEDS to illuminate. I don't know enough about X.25 etc to get any further than that. Let me know if you are interested. However, I am located in Dublin, Ireland so I am not sure how it would be possible to get the stuff to you if you do want it. Regards, Peter Coghlan.
