As a teenager I got my first 8-bit computer. A lot of my friends had Commodore 64. But a good computer salesman sold me and my dad on the british Amstrad CPC 6128[0]. It had the disk drive and a green monitor. Great computer. Great salesman. They had this newfangled Commodore Amiga but he did not know much about it. It was at the same price but without a monitor so my dad reasoned it would be better as I would then not occupy the living room TV with my computer. I could have jumpstarted my career on 16 bit. I could have been a contender!
The Amstrad had a Z80 CPU and ran Locomotive Basic when powered on. But it came with a disk containing CPM Plus 3.0. That was used for "business-like" things such as copying files using "pip to_me from_you".
That in turn made me the local über-geek in the computer room in my public school. They had 2 expensive danish made and rather rare Intel 80186 (yes - 80 one 86) based RC Piccoline[1] computers. They in turn each had 4 terminals and 1 dot matrix printer (a typical school setup at the time). A fact which never really dawned upon me at the time what "Concurrent" in CCP/M meant. My geek flex was when the vice principal fetched me during a regular class to help him remove a defamatory text file from a 5,25" floppy disk. He was not able to delete the file himself. I identified the "read-only" attribute was set and such wizardry was rarely seen around those parts.
Back in the day when computing was much more heterogeneous and fun. I am sitting here behind my Ryzen monster but still yearn for those days.
Now, kids. Get off my lawn :-)
