I would say go ahead with the old computer but don't spend any more money (or at least very little) on it. Try to find some PC100 memory for free, it is too expensive to buy new...about $25 for a 256 Mb stick-the same as for 1 gb of modern memory. Remember that you can get a dual core CPU, 2 gb memory and 64 bit Win 7 refurbished computer for about $125 (even then I would recommend another 2 gb of memory)

Can't give you a real history, but used it when I was a navy electronics tech from 1961-1966. Seems to me it was one of a series that covered to 16 ghz. (Needed that range to work on the ECM equipment)
