Turbo Rascal rulez!
Turbo Rascal is a development environment for the Commodore computers but also for others like NES and so on. It is a bit different from other IDE because it is based on a Pascal-like language.

HP 42s the BEST calculator and its FAST MODE
The HP 42S accompanied me throughout my university career, secretly designed for me some function graphs and with its 7KB alphanumeric also managed to make me keep some secret notes.

Memory Madness 2020
In 1985, all my work started with a VIC-20 with 5Kb of RAM, and only 3583 bytes free for the BASIC. With 3 more kilobytes, VIC-20 would be able to unveil its more versatile graphic capabilities, but we have no luck. In 1995 I got a 8 MegaBytes computer with 512MB hard disk as workstation …
