I have just been offered an altair computer, it's been sitting in the back of a garage, unused for some time. I don't want to just plug it in and power it up right away do I ? Inspect -- what am I looking for? Clean -- best method? It is described as "not having switches or blinking lights", having floppy disks, having been used for somthing to do with ham radio. This is in advance of actually getting the computer,
