On a recent holiday to Bangkok, I visited the science museum and planetarium that is there. While eating lunch I was very surprised to see some very recognisable vintage computer equipment in almost open-air storage (sadly they are all slowly rotting away slowly). I managed to get some photos, I wish I had time to get more, but I was in a no-public area! I've identified some of the equipment, but I really appreciate the rest of the equipment being identified, for the sake of my classroom wall! I suspect that some of the smaller machines may day back to the 1940's (or maybe earlier).
Can you help in identifying any of these?
Any clues on this lot? Especially the big devices underneath? The keyboards might belong to a Raytheon PTS-100 of which there seems to be several (another photo)

Raytheon PTS-100, there are several of these or similar machines

This one has really got my curiosity. Any clues? I suspect it might be wartime or earlier.

This is my wall display, I'm linking the hardware I've photographed to information found on the internet about those devices and with better photos.
