Wang VS 75E

Purchase

This was an ebay purchase made on the 12 May 2023 and was picked up from Luton on the 19 May 2003. The items had been stored in the top floor offices, possibly an accountants office, below was a manufacturing business both of which have long gone.

There was; a Wang 75E, 12 terminals, 3 printers, manuals, software and some cables. Additional were some cassette type hard disks but no hard drives and no tape backup drives.

I want to just plug the thing in and see if it works but I am not sure, with old electronics over 35 years old. What do you think? Is there a process I should go through before the power up? Your help would be appreciated.

With the terminals I could just plug one in to see if it works as I have 12 of them. I have seen with other similar projects people are checking capacitors and possibly recapping. Is this required?

I have tested one of the terminals which has tripped the RCD and I am now going through some diagnostics.

Looks like I am going to have to recap some of the terminal monitors. One monitor down!! I have opened the monitor case up and found the protection capacitor split in two which explaines the bang and all the smoke.

Another monitor down!! Opened the monitor case and found the same protection capacitor blown. Anyone know why? I assume it's age and storage. The monitor houses several circuit boards and this capacitor is on the power board. Do I change all the capacitors or just the blown one or just the power board?

The capacitor is 275~ 0.1 Wima MP3. I can replace this and retry!!
