OK, the cabinet was only half filled: the HDD housing took up the bottom 1/4 vertically and had the fixed and removable Discs, drive motor, cooling fans and Controller Board for the HDD’s.
The Power Distribution and Voltage Control Box was at the rear in between along with more fans. It was no bigger than a shoebox. So plenty of space.
Then the next 1/4 was MT except for a few Flat Data Cables that were probably 100 wires each going up to the actual CPU and more cooling fans.
And then were the Peripheral Control Circuit Panels with slide locks and there were 1 each for the (4) CRT’s, (2) Printers, (1) for the Dual 8” Floppy Drives and (1) for the HDD. Those Circuit Boards were probably 18” x 24” x 1/2” thick each.
There was probably 150’ of assorted Ribbon Cables going between all the Components.
So there was plenty of Cooling Fans and Airspace in the Cabinet.
The remaining MT space was for Hardware upgrades to run up to a Maximum of 4 Stores with the same count of CRT’s, Printers as Store #1 except that it would barely run the 1 Store.
Plus there would have been Modems or Multiplexers for the other 3 Stores.
The last I knew that Monster was replaced by a DG Server that was 2’ x 2’ x 3’ with a 52,000,000TB (just kidding about size) Mirrored HDD and Multiplexers and the Store Count was 8 or 9 plus the Warehouse. And there were 2 remote Master Terminals at Owner Homes to look over everything remotely at anytime.
interesting
