Ideally, from this point of view, any interface where the input (control) device is: a touchscreen, a tablet (by the way, IBM tablets emulate a mouse), and a light pen/gun can be considered. The gun is already available on the SPECCY (see Spectrofon #20), if only someone would connect an active mouse - it would be great. Unfortunately, there is none of this on the ...

Compromise.

The desire to humanize drawing in some way led me to try to implement a light pen. In general, this is feasible with 2 transistors (about 10 components total), with adjustable sensitivity. The signal - 2 bits - was fed through the Kempston Joystick (1 bit from a button located on ... 

 ...s gained wide popularity in the school educational sphere, as dozens of schools were equipped with them relatively quickly. I even got to see classrooms with "Magic" computers that were equipped with light pens!

My interest was not in the fact that they were being taken out, no,...

It was built on transistors and also had an excellent cathode-ray monitor, a sound reproduction device, and even a light pen that could be used to draw on the screen. Most importantly, it did not have a batch processing system; a person would insert a tape with a program and immediately receive results. Students were allow...
