I have been subscribed to the list for a few years. I rarely make posts. I really enjoy vintage computing but have little knowledge to offer. I recently purchased an Ampex computer/work station at a garage sale. I did not know exactly what I was buying and the seller was also unsure what it was (he got it from someone who was dumping it if I remember correctly). I am trying to understand what it is. There is no keyboard. There was one disk in the drive. When powered on, nothing appears on the screen though there is a humming noise which I'm almost certain is only the fan. The red light does not come on. I've tried inserting the disk and removing it once or twice and thought I heard the *very* faint sound of the drive but it never seems to fully power up or read the disk. The back of the "computer" has various in/outputs that I am not familiar with ("Chan A" "Concen" "SMPTE") The sticker on the back says it contains "multichannel software" version 9.4. I thought that might indicate it is some type of terminal that needs to be used with a mainframe?? I did some research but couldn't figure out what it is. Any information/help is appreciated. You can see pictures of this (including pics of it opened up) at https://imgur.com/a/WfHORyP Secondarily; if this ends up being something I can't make use of - if anyone is interested let me know.
