At first a control console was built and filled with state of the art? chuck outs. Anything that looked technical was added along with rather a lot of light bulbs!
In the early 90’s the TARDIS gained an extension over doubling its size, it was at this point things went a tad more Enterprise than TARDIS!
I built large glass panels and sloped controls, some functioning. Yellow & red alerts were added, self destruct mode & a sound studio where as kids we made radio shows which later became video shows called Totally Tapped, loosely based on Saturday morning shows of the time, an age gone by now when kids had imagination!
Once I discovered cars the TARDIS fell into moth balls, used mainly for storage it sat there unloved for about 9 years
