One level up

Images of frustration

1024x768    Full size		Here you see a full front view of the machine while powered up.
1024x768    Full size		The upper half of the front.
1024x768    Full size		The front panel controls
1024x768    Full size		The vacuum columns with a tape loaded.
1024x768    Full size		The machine's backside
1024x768    Full size		The capstan belt is back in place, and the motor as well.
1024x768    Full size		Where to get such a belt???
1024x768    Full size		The compressor/vacuum pump
1024x768    Full size		This is the read-write head assembly in the upper position.
1024x768    Full size		The head again
1024x768    Full size		A loop chamber zone switch
1024x768    Full size		Column switches... uh oh....
1024x768    Full size		Here you can see the top contact.
1024x768    Full size		The place where the swich has been removed from. Oh, you have to turn your head upside-down....
1024x768    Full size		This is the underside of one of the zone switches. The white greasy stuff is "Dow Corning vacuum grease". Don't know where to buy it. Is needed to correctly reassemble and remount the switches.
1024x768    Full size		Upper side of the removed switch
1024x768    Full size		Interior of the switch after removal of lower membrane (which is not broken). But the upper membrane which is not easily removable (see the glue) is broken.
1024x768    Full size		There's he whole :-(
1024x768    Full size		Some technical background on the loop regulation
1024x768    Full size		That's the way the vacuum switches are built. The diaphragms are *not* easily replaced :-( Any suggestions?
1024x768    Full size		No comment
1024x768    Full size		The whole power-up and power-down sequencing is done via those mercury-wetted contact relays. They sit in sockets like vacuum tubes.
1024x768    Full size		The drive is not from the sixties. Everything is dated 1970.
1024x768    Full size		9101 is the machine number of the second H316 I *think*
1024x768    Full size		The circuit breakers in "chassis C"
1024x768    Full size		I have found the type plate.
1024x768    Full size		No comment
1024x768    Full size		The loop chamber vacuum sensor. It is not really ok as well. But I *hope* that there's no problem with the membrane....
1024x768    Full size		The TAD package connector - but there's no TAD package :-(
1024x768    Full size		The write head drivers are *not* missing.
1024x768    Full size		What do I configure here?
1024x768    Full size		One of the sense amplifier boards still in the machine
1024x768    Full size		No comment
