I implemented the very slow flood fill for Spectricon, the paint software.

The paint program we used was called "fged". It could generate C code for animations. People would spend hours generating their animation masterpiece, then bring their friends to play it back for them.

We need a lot more photos of these machines. Maybe even 3D scans.

They should be preserved somehow. Even a modern web browser has enough compute power to emulate a network of them probably.

We can preserve their function, but the physical experience of using them requires the ability to produce a physical approximation. I can say the C64 Maxi is a low-cost and pretty good approximation of both a C64 and a VIC20 computer. I only wish it could also be a C16 and a Plus/4.

I think I remember fged. Wire-frame transformations were popular at that time. There was also IPaint. Spectricon could paint in various graphic modes including 16 colors on the newer Icon computer. The flood fill's hand coded 80186 assembly was still slow due required calls to the Cemcorp graphics API.

> Each Unisys ICON came with its own monitor and a very robust keyboard with a trackball embedded in it. The trackballs were robust indeed. Due to the client/server nature; a classroom of kids logging in at the same time could take several minutes and most of that time would be filled with a classroom of 7 year olds spinning the heck out of the tennis ball sized trackball. One more knowledgeable teacher once told us…

Consider yourself lucky. My public high school in Ontario was supposed to be a "magnet school for the gifted" and instead turned out to be a scam. The computer class teacher was absent for a year, and the substitute teacher insisted that the keyboard and mouse cords should be neatly arranged at the end of each class as if it was a knitting class. The "coursework" consisted of learning how to type out "business memos"…

My secondary school changed headmaster in 1990. The new headmaster declared that "computers were a passing fad" and ended all IT lessons.

Here are lots of photos: https://vintagecomputer.ca/the-burroughs-icon-computer/

It looks like this computer is also known as the Burroughs ICON and the CEMCORP Icon.

Earlier quoted context omitted.

I agree, recreating them physically would be just as important. I'm university I used the HP48 calculator. There's emulators for it, but it's not the same as holding the old calculator in my hands, the tactile feel of the buttons, looking at the reflective dot matrix screen that would flicker under the fluorescent lights.
