OMG !!! That looks a whole lot like the one that was plugged into the first Server we had when the Parts Store went to Computer Inventory and POS Invoices.
We were remodeling the office it was in and had it connected to an extension cord.
I tripped over the cord and unplugged it. I tried to plug it back in before things shutdown...
Well I got it plugged back in, and FRIED EVERY CIRCUIT BOARD IN THE MACHINE!!!!!
This was back in the days when the Server was the size of a big steel desk and had like 2 x 2 boards that could be changed out by unlocking 2 levers and it had about 15 boards inside plus a 10MB (Yes one-zero aka Ten) HDD with a MIRROR 10MB removable for Backup of Data. Those HDDs were like 18 inches diameter. We had 2 of those, 1 for Odd Days, 1 for Even Days.
Hard to believe that even ran the 1 Store. We had 1 Master CRT, 3 Slave CRTs for Invoicing, 1 Tractor Feed Invoice Printer that had 8.5 wide Blank Invoice paper and 1 Double Width Report & Stock Order Printer. But it did the job better than Us Handwriting Invoices, looking up prices, extending out the prices, Subtotaling, then calculate the Tax and do a Grandtotal. Then we had a Manual Index Card System for inventory...
My little plug stunt sent us back to the Dark Age for 3 days before the Hardware Service Guys got us up and running again.
The Hardware Guys told Me if I had just waited for it to shut down completely and then plug it back in that it would have been fine.
