This is a simulation of the Logix 0-600 computer. This was a toy from the early 1970's, before microcomputers existed.
There are pictures of this computer here.
It is written in Python with TKinter (which is distributed with Python, or at least Windows download is). You can install Python on pretty much any computer, if you don't already have it. Go to Python.org if you need to download it.
Then download and unzip this file. Run the file 0600.py or type "python 0600.py". If you're using Windows you might want to rename it to 0600.pyw so it doesn't open an extra black window.
The toy was battery powered. It had ten light bulbs along the top behind a brown cover. The bases of the light bulbs were all connected to one end of the batteries. The other end of the batteries was connected to a connector that you could plug into from the top (the leftmost top set of three holes). The other terminals of the light bulbs were also connected to connectors you could plug into from the top (the sets of three holes below each light). It had ten sliders along the bottom which were 5-pole switches. It had one push-button at the bottom left.
All of the connectors were in groups of three holes that are electrically connected (they plug into one metal contact.
The holes along the sliders are grouped into 5 blocks of four triples of holes. The top three holes on one side connect to the top three holes on the other side when the sliders are slid in. The bottom three holes on one side connect to the bottom three holes on the other side when the sliders are slid out.
All circuits must start from one of the top left triple of holes and go through the switches and to the lights. (In the real toy, the power supply group was at the top more, but I moved it in this similation to fit in the window better, so it's still one of the sets of holes furthest to the left.)
The two groups of three holes below the power holes are connected to the pushbutton at the bottom. Use the mouse to push the button. It stays pressed only as long as you hold the mouse button down.
To run wires, click on the starting hole, and while holding the mouse button, move to the ending hole and let up. Right-click on wires to delete them. Click on the slider labels or lights to be able to type onto them.
Then, to use your program, click on sliders to move the switches or click on the button on the left to press it.
To get some additional functions, click on the context menu key that is anachronistically duct-taped on the right side above the pushbutton. You can load and save programs, clear everything, turn on a debugging mode, and exit. The real toy did not have these things of course.
