I have an old NCR machine that I would like to get up and running. While I have everything intact what I really need is some way of interfacing it. There are numerous amounts of low density DB15 ports that I think have nothing to do with Ethernet since the spot that is labeled Ethernet is covered up with nothing behind the cover. What can I use to find out what is on this thing. The numbers on the data sticker are: class 3470-MSTD model 0202 serial 36-18259367 tracer 36-002591 Any ideas? I would also like to know where I can find a power supply for an Amiga A500. Charles Oblender
