IBM 5150 Round Port Cap

Details

This is a “cap” for the round port which sits above the keyboard and cassette ports on an IBM 5150 (any maybe other contemporary models).

The original is a metal cap (which I have) but I wanted to use that empty port to mount two external switches for use with my PC Sprint Accelerator. One is a 6x6mm tactile momentary switch which is a reset button and the other is a square push button toggle switch to change between normal and turbo mode.
